Description
This command administratively disables an entity. When disabled, an entity does not change, reset, or remove any configuration settings or statistics.
The operational state of the entity is disabled as well as the operational state of any entities contained within. Many objects must be shut down before they can be deleted.
When used with the ethernet>efm-oam command, shutdown enables tunneling on the port (see tunneling), and no shutdown enables Ethernet EFM OAM 802.3ah.
The no form of this command administratively enables an entity.
Default
card – no shutdown
mda – no shutdown
port – shutdown
scada – shutdown
scada>branch – no shutdown
input – no shutdown (for Auxiliary Alarm card and chassis alarm inputs)
alarm – shutdown (for Auxiliary Alarm card)
output – shutdown (for Auxiliary Alarm card)
lag – shutdown
Card Commands
card
Syntax
[no] card slot-number
Context
config
Description
This mandatory command is the first step in activating the IOM software: designating it a slot position in the chassis. On the 7705 SAR, the slot number is always 1. The IOM software must be activated before the adapter cards and ports can be configured. The no form of this command removes the card from the configuration. All associated ports, services, and adapter cards must be shut down.
Default
n/a
Parameters
- slot-number
the slot number of the card in the chassis
card-type
Syntax
card-type card-type
no card-type
Context
config>card
Description
This mandatory command is the second step in activating the IOM software: designating the card type. The card type can be preprovisioned, meaning that the card does not need to be installed in the chassis. On the 7705 SAR, the card type is always iom-sar.
A card must be provisioned (configured) before an adapter card or port can be configured.
A card can only be provisioned in a slot that is vacant, which means that no other card can be provisioned for that particular slot. To reconfigure a slot position, use the no form of this command to remove the current information. Port and adapter card information must be shut down.
A card can only be provisioned in a slot if the card type is allowed in the slot. An error message is generated if an attempt is made to provision a card type that is not allowed.
The no form of this command removes the card from the configuration. This operation requires that the card be administratively shut down. All dependencies to ports on this card must be shut down and removed from the configuration before issuing the no card-type command.
Default
n/a
Parameters
- card-type
the type of card to be configured and installed in the slot
Adapter Card Commands
mda
Syntax
[no] mda mda-slot
Context
config>card
Description
This mandatory command enables access to a card’s MDA CLI context to configure adapter cards.
Default
n/a
Parameters
- mda-slot
the adapter card or module slot number to be configured
ais-propagation
Syntax
ais-propagation {enable | disable}
Context
config>card>mda
Description
This command enables the 7705 SAR to interoperate with SDH networks that use subnetwork connection protection (SNCP). When ais-propagation is enabled, the 7705 SAR can use SDH signaling to make pseudowire switching decisions on Cpipes configured for redundancy.
For more information about 7705 SAR interoperation with SDH SNCP, see the 7705 SAR Services Guide, ‟AIS Fault Propagation”.
Default
n/a
clock-mode
Syntax
clock-mode adaptive
clock-mode {dcr-acr | differential}[timestamp-freq {19440 | 25000 | 77760 | 103680}]
Context
config>card>mda
Description
This command defines the clocking mode and the associated timestamp frequency (if differential or dcr-acr clocking mode is configured).
All clock modes are supported on the following:
16-port T1/E1 ASAP Adapter card
32-port T1/E1 ASAP Adapter card
7705 SAR-A (variant with T1/E1 ports)
7705 SAR-M (variants with T1/E1 ports)
7705 SAR-X
T1/E1 ports on the 4-port T1/E1 and RS-232 Combination module (the clock frequency value configured for dcr-acr clock mode or differential clock mode on one module takes effect on both modules installed in the 7705 SAR-H)
Only differential mode is supported on the following cards:
4-port OC3/STM1 / 1-port OC12/STM4 Adapter card (DS1/E1 channels)
4-port DS3/E3 Adapter card (clear channel DS3/E3 ports and DS1/E1 channels on channelized DS3 ports (E3 ports cannot be channelized)); differential mode on DS1/E1 channels is supported only on the first three ports of the card
Default
adaptive (if no clocking mode is configured)
differential (for 4-port OC3/STM1 / 1-port OC12/STM4 Adapter card and 4-port DS3/E3 Adapter card)
If differential or dcr-acr clocking mode is configured on the 7705 SAR-M, 7705 SAR-A, 7705 SAR-X, or 4-port T1/E1 and RS-232 Combination module, the default timestamp frequency is 103680.
If differential or dcr-acr clocking mode is configured on the 16-port T1/E1 ASAP Adapter card or the 32-port T1/E1 ASAP Adapter card, the default timestamp frequency is 77760.
For the 4-port OC3/STM1 / 1-port OC12/STM4 Adapter card and the 4-port DS3/E3 Adapter card, the default timestamp frequency is 77760.
Parameters
- adaptive
enables adaptive clock recovery
- dcr-acr
enables DCR and ACR on different ports of the same card
- differential
enables differential clock recovery
- timestamp-freq
sets the optional timestamp frequency
- 19440
sets the timestamp frequency to 19440 Hz (19.44 MHz) for Y.1413 compliance
- 25000
sets the timestamp frequency to 25000 Hz (25 MHz) for Ethernet-based systems
- 77760
sets the timestamp frequency to 77760 Hz (77.76 MHz) for interoperation with SONET/SDN-based systems such as TSS-5
- 103680
sets the timestamp frequency to 103680 Hz (103.68 MHz), recommended for any operation over 100 MHz
Note: The 25000 and 103680 options are not supported on the 16-port T1/E1 ASAP Adapter card or the 32-port T1/E1 ASAP Adapter card. The 19440, 25000, and 103680 options are not supported on the 4-port OC3/STM1 / 1-port OC12/STM4 Adapter card or the 4-port DS3/E3 Adapter card.
fabric-stats-enabled
Syntax
[no] fabric-stats-enabled
Context
config>card>mda
Description
This command enables the fabric port statistics counter to count egress traffic toward a specified adapter card. The CSM allows the collection of fabric statistics from only one fabric port at any specific time. To change the port statistics counter to a different adapter card, turn off statistics collection on the assigned adapter card by using no fabric-stats-enabled and then enabling statistics collection on another adapter card.
mda-mode
Syntax
mda-mode mda-mode
no mda-mode
Context
config>card>mda
Description
This command configures the set of software services that are enabled for a specific adapter card.
The cem-atm-ppp and cem-fr-hdlc-ppp parameter values are used to configure the appropriate encapsulation methods that are required to support pseudowire services. These values apply to the following adapter cards:
16-port T1/E1 ASAP Adapter card
32-port T1/E1 ASAP Adapter card
4-port DS3/E3 Adapter card
The card-level encapsulation capabilities must be configured before the encap-type parameter is configured at the port level.
Thex10-1gb-sfp and x1-10gb-sf+ parameter values are used for the 10-port 1GigE/1-port 10GigE X-Adapter card to define whether the card operates in 10-port 1GigE mode or 1-port 10GigE mode.
The p4-oc3 and p1-oc12 parameter values are used for the 4-port OC3/STM1 / 1-port OC12/STM4 Adapter card to define whether the card operates in 4-port OC3/STM1 mode or 1-port OC12/STM4 mode.
The mddb, pcm, and vcb parameter values are used for the Integrated Services card to define which SCADA application is active on the card.
The no form of this command sets the mda-mode back to the card’s default mode. All service and port/channel configurations associated with the adapter card must be removed before the mda-mode can be changed. On the 4-port OC3/STM1 / 1-port OC12/STM4 Adapter card, changing the mode causes the adapter card to reset.
Default
x1-10gb-sf+ (for the 10-port 1GigE/1-port 10GigE X-Adapter card)
cem-atm-ppp (for the T1/E1 ASAP adapter cards and 4-port DS3/E3 Adapter card)
p4-oc3 (for the 4-port OC3/STM1 / 1-port OC12/STM4 Adapter card)
mddb (for the Integrated Services card)
Parameters
- mda-mode
the encapsulation mode for the adapter card to be provisioned
mda-type
Syntax
mda-type mda-type
no mda-type
Context
config>card>mda
Description
This mandatory command provisions a specific adapter card or module type to the device configuration for the slot. The adapter card or module can be preprovisioned, but it must be provisioned before ports can be configured. Ports can be configured after the adapter card or module is properly provisioned.
A maximum of 6 adapter cards can be installed in a 7705 SAR-8 Shelf V2 chassis, and a maximum of 12 adapter cards and 4 XMDA adapter cards can be installed in a 7705 SAR-18 chassis. One module can be installed in a 7705 SAR-M chassis. A maximum of two modules can be installed in a 7705 SAR-H chassis. Only one adapter card or module can be provisioned per MDA or module slot. To modify an MDA or module slot, shut down all port associations.
A medium severity alarm is generated if an adapter card or module is inserted that does not match the adapter card or module type configured for the slot. This alarm is cleared when the correct adapter card or module is inserted or the configuration is modified. A high severity alarm is raised if an administratively enabled adapter card or module is removed from the chassis. This alarm is cleared if either the correct adapter card or module type is inserted or the configuration is modified. A low severity trap is issued if an administratively disabled adapter card or module is removed.
An alarm is raised if partial or complete adapter card or module failure is detected. The alarm is cleared when the error condition ceases.
The no form of this command deletes the adapter card or module from the configuration. The adapter card or module must be administratively shut down before it can be deleted from the configuration. Before an adapter card or module can be shut down, all port associations with this adapter card or module, for example SAPs and IP interfaces, must be shut down first.
Default
n/a
Parameters
- mda-type
the type of adapter card to be provisioned
poe-power-source
Syntax
poe-power-source {internal | external | none}
no poe-power-source
Context
config>card>mda
Description
This command specifies whether the internal system-level PoE power supply or an external PoE power supply is used to power the PoE-capable ports on a 7705 SAR chassis.
When the 7705 SAR-H is configured for the internal power supply, standard 15 W PoE can be enabled only on ports 5 and 6. Port 5 can also support 34 W PoE+, but in that case, port 6 cannot support PoE. When configured for the external PoE power supply, all four PoE-capable ports support a combination of standard 15 W PoE and 34 W PoE+, with a maximum power delivery of 83 W among all PoE-enabled ports. See the 7705 SAR-H Chassis Installation Guide, ‟Ethernet Ports”, for information about supported combinations and restrictions.
The following chassis types only support the internal system-level PoE power supply:
7705 SAR-Hc
7705 SAR-Wx
The no form of this command disables the PoE power supply on the node.
Default
internal
Parameters
- internal
specifies that the internal PoE power source be used for the PoE-capable ports
- external
specifies that an external PoE power source be used for the PoE-capable ports
- none
specifies that no internal or external PoE power source is used

application
Syntax
application {broadcast | teleprotection | vcb | vcb-branch-initiate}
Context
config>card>mda>vcb
Description
This command specifies the operating mode for the VCB application. The mode is set at the card level and applies to all bridges configured on the card.
Default
vcb
Parameters
- broadcast
only one branch on the bridge (fixed as branch 1) has control of the bridge to transmit, and all other branches are in listen-only mode
- teleprotection
each teleprotection relay transmits state information on discrete frequencies so that each relay can both hear what the other relays are transmitting as well as transmit its own information to the other relays
- vcb
one branch talks and all other branches on the bridge can hear
- vcb-branch-initiate
branches on the bridge are only enabled (unmuted) when the attached base station signals its presence by grounding the M-lead on the interface connected to the bridge. Upon receiving the grounded M-lead via T1/E1 ABCD bits or TDM PW signaling, the bridge unmutes the associated branch. When the ground is removed, the branch is muted again.

alarm.d-alarm-num [name]
where:
slot = card slot number for IOM (always 1 on the 7705 SAR)
mda = Ethernet adapter card or Auxiliary Alarm card slot number (for Ethernet modules or ports on platforms with no card slots, the mda slot number is preconfigured)
port = port number for Ethernet ports
d = digital input
a = analog input
alarm-num = alarm port number (1 to 24 for digital on the Auxiliary Alarm card, 1 to 4 for digital on the four chassis alarm inputs, 1 or 2 for analog)
name = optional name assigned to the input
for example: alarm-1/3.d-3
windowOpen3
alarm.d-1
The name option lets users assign a more meaningful name (must be unique) to the alarm input; for example, windowOpen3 might be more meaningful to a user than the identifier alarm-1/3.d-3. Once the name has been configured, it can be used interchangeably with the alarm input identifier; for example, windowOpen3 can be used instead of alarm-1/3.d-3 as an alarm input trigger.

APS Port Commands
port
Syntax
[no] port {aps-id}
Context
config
Description
This command enables access to the context to configure APS on SONET/SDH ports and assigns an APS group ID. Both working and protection circuits must be configured with the same APS group ID on either the same 7705 SAR node (SC-APS) or on two 7705 SAR nodes (MC-APS).
Parameters
- aps
keyword
- id
1 to 8
aps
Syntax
aps
Context
config>port
Description
This command configures APS on SONET/SDH ports. An APS group contains a working and protection circuit with the same APS group ID on either a single 7705 SAR node (SC-APS) or on two 7705 SAR nodes (MC-APS).
The working circuit must be connected to the peer working circuit, and the protection circuit must be connected to the peer protection circuit.
The aps command is only available for APS groups, not for physical ports.
advertise-interval
Syntax
advertise-interval advertise-interval
no advertise-interval
Context
config>port>aps
Description
This command specifies the time interval, in 100s of milliseconds, between ‟I am operational” messages sent by the protection and working circuits to their neighbor in an MC-APS group. The advertise-interval value is valid only for an MC-APS.
Default
10
Parameters
- advertise-interval
the time interval, in 100s of milliseconds, between transmitted operational messages
hold-time
Syntax
hold-time hold-time
no hold-time
Context
config>port>aps
Description
This command specifies how much time can pass without the node receiving an advertise packet from its neighbor before the MC-APS signaling link is considered operationally down. The hold time is in 100s of milliseconds and is usually the advertise-interval value multiplied by 3.
Parameters
- hold-time
specifies, in 100s of milliseconds, how long to wait for an APS advertise packet before the neighbor in an MC-APS group is considered operationally down.
hold-time-aps
Syntax
hold-time-aps {[lsignal-fail sf-time] [lsignal-degrade sd-time]}
no hold-time-aps
Context
config>port>aps
Description
This command configures hold-down timers to debounce signal failure conditions (lais, b2err-sf) and signal degrade conditions (b2err-sd) for 1+1 unidirectional SC-APS switching mode. If the signal fail or signal degrade conditions exceed the configured hold-down time, APS is activated.
Default
no hold-time-aps (values are 0)
Parameters
- sf-time
the signal failure hold-down time in milliseconds, from 1 to 100
- sd-time
the signal degrade hold-down time in milliseconds, from 1 to 100
neighbor
Syntax
neighbor ip-address
no neighbor
Context
config>port>aps
Description
This command specifies the neighbor's IP address in an MC-APS group. When the value of the neighbor IP address is set to 0.0.0.0, or not set, this implies that the APS group is configured as an SC-APS group.
The route to the neighbor must not traverse the MC-APS member (working or protection) circuits. It is recommended that the neighbor IP address configured be on a shared network between the routers that own the working and protection circuits. The node should be connected with a direct interface to ensure optimum failover time.
By default, no neighbor address is configured and both the working and protection circuits should be configured on the same router as an SC-APS group.
Default
0.0.0.0
Parameters
- ip-address
specifies the neighbor's IP address for MC-APS.
protect-circuit
Syntax
protect-circuit port-id
no protect-circuit
Context
config>port>aps
Description
This command configures a physical port that will act as the protection circuit for this APS group.
The protection circuit port must contain only the default configuration and cannot belong to another APS group. The protection circuit port must be of the same type as the working circuit (SONET/SDH) for the APS group; if it is not, the command will return an error.
A protection circuit can only be added if the working circuit already exists. The protection circuit must be removed from the configuration before the working circuit can be removed.
When a port is a protection circuit of an APS group, the configuration options available in the config>port port-id>sonet-sdh context are not allowed for that port unless they are in the following exception list:
clock-source
[no] loopback
[no] report-alarm
section-trace
[no] threshold
When a port is configured as a protection circuit of an APS group, the configurations listed above and all service configurations related to the APS port are operationally inherited by the protection circuit. If the protection circuit cannot inherit the configurations (due to resource limitations), the configuration attempt fails and an error is returned to the user.
The protection circuit must be shut down before it can be removed from the APS group port. The inherited configuration for the circuit and APS operational commands for that circuit are not preserved when the circuit is removed from the APS group.
The no form of this command removes the protection circuit.
Default
n/a
Parameters
- port-id
the physical port that will act as the protection circuit for this APS group in the format slot/mda/port
rdi-alarms
Syntax
[no] rdi-alarms {suppress | circuit}
Context
config>port>aps
Description
This command configures how RDI alarms (line, path, section) are generated on physical circuits of an APS port. The command is only supported in 1+1 unidirectional SC-APS mode. When you configure RDI alarms on a port on the 2-port OC3/STM1 Channelized Adapter card, the second port is automatically configured with a matching RDI alarms setting. As a consequence, both ports will then support only 1+1 unidirectional SC-APS mode.
Default
circuit
Parameters
- suppress
RDI hardware generation on working and protection circuits is suppressed. No alarms are generated upon an Rx failure of that circuit.
- circuit
RDI alarms are hardware-generated independently on each working and protection circuit based on an Rx failure of that circuit, regardless of APS line status
revert-time
Syntax
revert-time minutes
no revert-time
Context
config>port>aps
Description
This command configures how long the 7705 SAR waits before switching back to the working circuit after it has been restored to service.
If the minutes value is changed, it takes effect at the next initiation of the wait-to-restore (WTR) timer.
This command does not modify the length of a WTR timer that has already been started. The WTR timer of a non-revertive switch can be assumed to be infinite.
The no form of this command restores the default (non-revertive) mode – the switch back does not occur unless the protection circuit fails or it is manually switched by the operator.
Parameters
- minutes
the time to wait, in minutes, before reverting to the working circuit after it has been restored to service
switching-mode
Syntax
switching mode {bi-directional | uni-1plus1}
Context
config>port>aps
Description
This command configures the switching mode for the APS port. SC-APS supports both bi-directional and uni-1plus1; MC-APS supports only bi-directional switching mode.
Default
bi-directional
Parameters
- bi-directional
provides protection in both directions
- uni-1plus1
provides protection in one direction
working-circuit
Syntax
working-circuit port-id
no working-circuit
Context
config>port>aps
Description
This command configures a physical port that will act as the working circuit for this APS group.
The working circuit port must contain only the default configuration and cannot be part of another APS group. The working circuit must be created before the protection circuit.
When a port is a working circuit of an APS group, the configuration options available in the config>port port-id>sonet-sdh context are not allowed for that port unless they are in the following exception list:
clock-source
[no] loopback
[no] report-alarm
section-trace
[no] threshold
When a port is configured as a working circuit of an APS group, the configurations listed above and all service configurations related to the APS port are operationally inherited by the working circuit from the APS group ID. If the working circuit cannot inherit that configuration (for example, due to resource limitations), the configuration attempt fails and an error is returned to the user.
The working circuit must be shut down before it can be removed from an APS group. The inherited configuration for the circuit and APS operational commands for that circuit are not preserved when the circuit is removed from the APS group.
All configurations for the APS group under the config>port context and its submenus and all configuration for services that use this APS group ID are preserved as a non-activated configuration since the APS group no longer has any physical circuits assigned.
The no form of this command removes the working circuit. The working circuit can only be removed from the configuration after the protection circuit has been removed.
Parameters
- port-id
the physical port that will act as the working circuit for this APS group in the format slot/mda/port

This command enables access to the context to configure Line Card Redundancy (LCR) parameters on T1/E1 ports or links. When the lcr-id is specified, this command assigns an LCR group ID. Both working and protection adapter cards must be configured with the same LCR group ID and on the same card type. For SC-LCR, both working and protection adapter cards must be on the same 7705 SAR node. For MC-LCR, the working and protection adapter cards must be on different 7705 SAR nodes.
Parameters
- lcr
keyword
- id
the LCR group ID, from 1 to 6
advertise-interval
Syntax
advertise-interval advertise-interval
no advertise-interval
Context
config>lcr
Description
This command specifies the time interval between ‟I am operational” messages sent by the protection and working adapter cards to their neighbors in an MC-LCR group. The advertise-interval value is valid only for MC-LCR.
Default
10
Parameters
- advertise-interval
the time interval, in tenths of a second, between transmitted operational messages
hold-time
Syntax
hold-time hold-time
no hold-time
Context
config>lcr
Description
This command specifies how much time can pass without the node receiving an advertise packet from its neighbor in an MC-LCR group before the neighbor is considered operationally down. The hold time is usually the advertise-interval value multiplied by 3.
Parameters
- hold-time
specifies, in 100s of milliseconds, how long to wait for an LCR advertise packet before the neighbor in an MC-LCR group is considered operationally down
neighbor
Syntax
neighbor ip-address
no neighbor
Context
config>lcr
Description
This command specifies the neighbor IP address in an MC-LCR group. When the value of the neighbor IP address is set to 0.0.0.0, or not set, this implies that the LCR group is configured as an SC-LCR group.
The route to the neighbor must not traverse the MC-LCR member (working or protection) adapter cards. It is recommended that the neighbor be on a shared network between the nodes that are configured with the working and protection cards. The node should be connected with a direct interface to ensure optimum failover time.
By default, no neighbor address is configured and both the working and protection adapter cards should be configured as an SC-LCR group on the same node.
Default
0.0.0.0
Parameters
- ip-address
specifies the neighbor IP address for MC-LCR
protect-mda
Syntax
protect-mda mda-id
no protect-mda
Context
config>lcr
Description
This command configures an adapter card that will act as the protection card for this LCR group.
The protection adapter card must contain only the default configuration and cannot belong to another LCR group. The protection card must be of the same type as the working adapter card for the LCR group; if it is not, the command will return an error.
A protection card can only be added if the working card already exists in the LCR group. The protection card must be removed from the configuration before the working card can be removed.
The protection card must be shut down before it can be removed from the LCR group. The inherited configuration for the protection card and the configured LCR operational commands for that card are not preserved when it is removed from the LCR group.
The no form of this command removes the protection card from the LCR group.
Default
no protect-mda
Parameters
- mda-id
the adapter card that will act as the protection card for this LCR group in the format slot/mda, where slot is the slot number of the IOM and mda is the slot number of the adapter card
revert-time
Syntax
revert-time minutes
no revert-time
Context
config>lcr
Description
This command configures how long the 7705 SAR waits before switching activity back to the working adapter card after it has been restored to service.
If the minutes value is changed, the change takes effect at the next initiation of the wait-to-restore (WTR) timer.
This command does not modify the duration of a WTR timer that has already been started. The WTR timer of a non-revertive switch can be assumed to be infinite.
The no form of this command restores the default (non-revertive) mode. The switch back does not occur unless the protection adapter card fails or activity is manually switched by the operator.
Default
no revert-time
Parameters
- minutes
the time to wait, in minutes, before reverting to the working adapter card after it has been restored to service
working-mda
Syntax
working-mda mda-id
no working-mda
Context
config>lcr
Description
This command configures an adapter card that will act as the working card for this LCR group.
The working card must contain only the default configuration and cannot be part of another LCR group. The working card must be created before the protection card.
The working card must be shut down before it can be removed from an LCR group. The inherited configuration for the card and configured LCR operational commands for that card are not preserved when it is removed from the LCR group.
The no form of this command removes the working card from the LCR group. The working card can only be removed from the configuration after the protection card has been removed.
Default
no working-mda
Parameters
- mda-id
the adapter card that will act as the working card for this LCR group in the format slot/mda, where slot is the slot number of the IOM and mda is the slot number of the adapter card

dwdm
Syntax
dwdm
Context
config>port
Description
This command configures the Dense Wavelength Division Multiplexing (DWDM) parameters.
channel
Syntax
channel channel
Context
config>port>dwdm
Description
This command configures the DWDM ITU channel for a tunable adapter card optical interface. The channel is expressed in a form that is derived from the laser's operational frequency. For example, 193.40 THz corresponds to DWDM ITU channel 34 in the 100 GHz grid and 193.45 THz corresponds to DWDM ITU channel 345 in the 50 GHz grid. The provisioned adapter card must support DWDM tunable optics. For a complete list of supported optics and associated adapter cards, contact your Nokia representative.
The DWDM channel must be set to a non-zero value before the port is set to no shutdown.
The port must be shut down before changing the DWDM channel, and the port must be a physical port to set the DWDM channel.
Parameters
- channel
specifies the channel
Ethernet Commands
ethernet
Syntax
ethernet
Context
config>port
Description
This command enables access to the context to configure Ethernet port attributes on all cards, modules, and chassis that support Ethernet. For the Packet Microwave Adapter card, this command does not apply to ports that support microwave awareness.
access
Syntax
access
Context
config>port>ethernet
Description
This command enables access to the context to configure access mode parameters.
egress
Syntax
egress
Context
config>port>ethernet>access
Description
This command enables access to the context to configure the CIR rate for the aggregate of all the unshaped 4-priority SAPs on the port and to configure the shaper policy.
shaper-policy
Syntax
shaper-policy name
no shaper-policy
Context
config>port>ethernet>access>egress
Description
This command assigns a shaper policy to the specified hybrid port.
For hybrid ports, the shaper policy is independently assigned to access or network egress traffic. When the Ethernet port mode is changed to hybrid mode, the default policy is assigned to access and network traffic. To change an access or network policy, use the commands config>port>ethernet> access>egress>shaper-policy and config>port>ethernet> network>egress>shaper-policy.
For access egress per-customer aggregate shaping, the shaper policy is assigned to a port and SAPs on that port must be bound to a shaper group within the shaper policy bound to that port.
The shaper policy defines shaper parameters such as shaper group, and PIR and CIR rates. The shaper policy is defined in the config>qos>shaper-policy context. See the 7705 SAR Quality of Service Guide, ‟QoS for Hybrid Ports” and ‟Per-Customer Aggregate shapers (Multiservice Site)”, for more information.
The port shaper rate applies to the bulk of access and network traffic. When the configured egress shaper rate is reached, both the access and network traffic scheduling pauses.
For hybrid ports, there can be a single shaper policy on access egress and a single shaper policy on network egress. Therefore, all the SAP traffic and all the network traffic is each bound to its own shaper group in the shaper policy (access and network shaper policy, respectively). In other words, shaped SAPs and the bulk/aggregate of unshaped SAPs are shaped together as per the shaper policy assigned to the access egress. A similar behavior applies to network traffic, where the shaped interfaces and the bulk/aggregate of unshaped interfaces are shaped together as per the shaper policy assigned to the network egress.
The no form of this command reverts to the default.
Default
‟default”
Parameters
- name
specifies an existing shaper policy name
unshaped-sap-cir
Syntax
unshaped-sap-cir cir-rate
no unshaped-sap-cir
Context
config>port>ethernet>access>egress
Description
This command sets the CIR rate for the aggregate of all the unshaped 4-priority SAPs on the port. The default cir-rate is 0 kb/s. When the cir-rate is set to max, the CIR rate adopts the maximum rate of the port, which is set using the egress-rate sub-rate command.
If the cir-rate is higher than the sub-rate, the cir-rate is stored in the configuration database but the sub-rate limit is used.
On a Gen-3-based port, this command can be set for mix-and-match LAG SAP purposes, but is not applied to the Gen-3-based port. See LAG Support on Mixed-Generation Hardware for more information.
The no form of the command sets the unshaped-sap-cir CIR rate to 0 kb/s.
Default
no unshaped-sap-cir
Parameters
- cir-rate
the CIR rate for the aggregate of all the unshaped 4-priority SAPs on the port
autonegotiate
Syntax
autonegotiate [limited]
no autonegotiate
Context
config>port>ethernet
Description
This command enables speed autonegotiation and duplex autonegotiation on Ethernet ports.
The 8-port Gigabit Ethernet Adapter card, 10-port 1GigE/1-port 10GigE X-Adapter card in x10-1gb-sfp mode, and Packet Microwave Adapter card support speed autonegotiation and duplex autonegotiation on all SFP ports. Each port can run in full-duplex mode or in half-duplex mode at 10 or 100 Mb/s.
The 6-port Ethernet 10Gbps Adapter card and the 7705 SAR-X support speed autonegotiation and duplex autonegotiation on all SFP ports; SFP+ ports do not support autonegotiation. Each SFP port can run in full-duplex mode or half-duplex mode at 10 Mb/s or 100 Mb/s, and in full-duplex mode at 1 Gb/s. Each SFP+ port can run in full-duplex mode at 10 Gb/s.
Speed autonegotiation takes place automatically — all ports are configured for speed autonegotiation by default. Speed autonegotiation might need to be disabled (for example, if a port must be forced to a certain speed or to avoid speed negotiation loops between the Ethernet Adapter card and other devices). To turn off speed autonegotiation for a port, the user configures the port speed manually.
When autonegotiation is disabled on a port, the port does not attempt to autonegotiate and will only operate at the speed and duplex settings configured for the port. Also, when autonegotiation is disabled, the tx and rx pauses are enabled automatically (the tx and rx pauses are negotiated with the far end if autonegotiation is enabled).
If the limited keyword option is specified, the port will autonegotiate but will only advertise a specific speed and duplex mode. The speed and duplex mode advertised are the settings configured for the port. One use for limited mode is for multispeed gigabit ports to force gigabit operation while keeping autonegotiation enabled for compliance with IEEE 801.3.
The no form of this command disables autonegotiation on this port.
Autonegotiation must not be disabled on an Ethernet port if the port is connected to an MPR-e radio.
For fiber SFP-based Gigabit Ethernet ports, it is recommended that autonegotiation be enabled. If autonegotiation is disabled and the configured speed does not correctly match the capability of the SFP, then the operational state of the link will remain down. Attempting to configure a speed and duplex mode to 1000 Mb/s, half-duplex, is an invalid combination and will be blocked from CLI.
For RJ45 interfaces, autonegotiation is mandatory for 1000Base-T operation (if disabled, the behavior is undefined).
If autonegotiation is turned off, the reception and transmission of IEEE 802.3x flow control frames is enabled by default and cannot be disabled. For more information, see Flow Control on Ethernet Ports.
Ports belonging to a microwave link must have limited autonegotiation enabled before the link can be added to a LAG.
Default
autonegotiate
cfm-loopback
Syntax
cfm-loopback priority {low | high | dot1p} [match-vlan {vlan-range | none}]
no cfm-loopback
Context
config>port>ethernet
Description
This command enables the port to respond to loopback messages (LBMs) and sets the queuing and scheduling conditions for handling CFM LBM frames. The user selects the desired QoS treatment by enabling the CFM loopback and including the high or low priority with the high or low keyword. The queue parameters and scheduler mappings associated with the high and low keywords are preconfigured and cannot be altered by the user.
The priority dot1p and match-vlan keywords apply only to physical ring ports on the 2-port 10GigE (Ethernet) Adapter card and 2-port 10GigE (Ethernet) module.
The parameters and mappings have the following settings:
for network egress or access egress, where 4-priority scheduling is enabled:
high-priority: either cir = port_speed, which applies to all frames that are scheduled via an expedited in-profile scheduler, or RR for all other (network egress queue) frames that reside in expedited queues and are in an in-profile state
low-priority: either cir = 0, pir = port_speed, which applies to all frames that are scheduled via a best effort out-of-profile scheduler, or RR for all other frames that reside in best-effort queues and are in an out-of-profile state
for the 8-port Gigabit Ethernet Adapter card, the 10-port 1GigE/1-port 10GigE X-Adapter card, and for the v-port on the 2-port 10GigE (Ethernet) Adapter card and 2-port 10GigE (Ethernet) module, for network egress, where 16-priority scheduling is enabled:
high-priority: has higher priority than any user frames
low-priority: has lower priority than any user frames
for the physical ring ports on the 2-port 10GigE (Ethernet) Adapter card or 2-port 10GigE (Ethernet) module, which can only operate as network egress, the priority of the LBR frame is derived from the dot1p setting of the received LBM frame. Based on the assigned ring-type network queue policy, dot1p-to-queue mapping is handled using the same mapping rule that applies to all other user frames.
CFM loopback support on a physical ring port on the 2-port 10GigE (Ethernet) Adapter card or 2-port 10GigE (Ethernet) module differs from other Ethernet ports. For these ports, cfm-loopback is configured using dot1p and an optional list of up to 16 VLANs. The null VLAN is always applied. The CFM loopback message will be processed if it does not contain a VLAN header, or if it contains a VLAN header with a VLAN ID that matches one in the configured match-vlan list.
The no form of the command disables the handling of CFM loopback frames.
Default
no cfm-loopback
Parameters
- low
sets the queue parameters and scheduler mappings, as described above
- high
sets the queue parameters and scheduler mappings, as described above
- dot1p
sets the queue parameters and scheduler mappings on a physical ring port, as described above
- match-vlan
sets the matching VLAN IDs that will allow a CFM loopback on a physical ring port when priority is set to dot1p, as described above
crc-monitor
Syntax
crc-monitor
Context
config>port>ethernet
Description
This command enables the context to configure Ethernet CRC monitoring parameters.
sd-threshold
Syntax
sd-threshold threshold [multiplier multiplier]
no sd-threshold
Context
config>port>ethernet>crc-monitor
Description
This command configures the error rate threshold at which the signal degrade condition is declared on an Ethernet interface. The error rate threshold value is the ratio of errored frames over total frames received, which is calculated as an average over the time set by the sliding window. The value is calculated as M ✕ 10E-N, where M is the optional multiplier used to increase the error ratio, and N is the rate of errored frames allowed (threshold). For example, 3 ✕ 10E-3 sets the error rate threshold at 3 errored frames per 1000 total frames received. If no window-size is configured, a default of 10-s is used. The CRC errors on the interface are sampled once per second.
The multiplier keyword is optional. If the multiplier keyword is omitted, the default value of 1 is used.
The no form of the command disables sd-threshold monitoring.
Default
no sd-threshold
Parameters
- threshold
specifies the threshold value
- multiplier
specifies the multiplier value
sf-threshold
Syntax
sf-threshold threshold [multiplier multiplier]
no sf-threshold
Context
config>port>ethernet>crc-monitor
Description
This command configures the error rate threshold at which the signal fail condition is declared on an Ethernet interface. The error rate threshold value is the ratio of errored frames over total frames received, which is calculated as an average over the time set by the sliding window. The value is calculated as M ✕ 10E-N, where M is the optional multiplier used to increase the error ratio, and N is the rate of errored frames allowed (threshold). For example, 3 ✕ 10E-3 sets the error rate threshold at 3 errored frames per 1000 total frames received. If no window-size is configured, a default of 10-s is used. The CRC errors on the interface are sampled once per second.
The multiplier keyword is optional. If the multiplier keyword is omitted, the default value of 1 is used.
The no form of the command disables sf-threshold monitoring.
Default
no sf-threshold
Parameters
- threshold
specifies the threshold value
- multiplier
specifies the multiplier value
window-size
Syntax
window-size seconds
no window-size
Context
config>port>ethernet>crc-monitor
Description
This command configures the sliding window size over which the Ethernet frames are sampled to detect signal fail or signal degrade conditions. The command is used jointly with the sd-threshold and the sf-threshold commands.
A sliding window (window-size) is used to calculate a statistical average of CRC error statistics collected every second. Each second, the oldest statistics are dropped from the calculation. For example, if the default 10-s sliding window is configured, at the 11th second the oldest second of statistical data is dropped and the 11th second is included. This sliding average is compared against the configured SD and SF thresholds to determine if the error rate over the window exceeds one or both of the thresholds, which will generate an alarm and log event.
The no form of the command disables window-size monitoring.
Default
10
Parameters
- seconds
specifies the size of the sliding window over which the errors are measured
dot1q-etype
Syntax
dot1q-etype 0x0600 to 0xffff
no dot1q-etype
Context
config>port>ethernet
Description
This command specifies the Ethertype expected when the port’s encapsulation type is dot1q.
IEEE 802.1q (also known as VLAN tagging) defines a process to channelize a single Ethernet port or v-port into VLANs. Each VLAN can represent a customer or an application. Up to 4096 VLANs can be configured per port. For more information about VLANs and VLAN tagging, see ‟VLL Services” in the 7705 SAR Services Guide.
The Ethertype specifies the protocol being carried in an Ethernet frame. In 802.1q, the Ethertype is set to the Tag Protocol Identifier (TPID) value of 0x8100, which identifies the frame as an IEE 802.1Q-tagged frame. As well, 2 bytes of Tag Control Information (TCI), followed by 2 bytes containing the frame’s original Ethertype are added to the frame. Together, the TPID and TCI make up the VLAN tag.
For Ethernet ports, when the port encap-type is qinq, the dot1q-etype value sets the Ethertype for the inner VLAN tag. The qinq encapsulation type is not supported by v-ports.
Network ports do not allow dot1q-etype settings.
The no form of this command resets the dot1q-etype value to the default.
Default
0x8100
Parameters
- 0x0600 to 0xffff
specifies the Ethertype to expect
down-when-looped
Syntax
down-when-looped
Context
config>port>ethernet
Description
This command enables the down-when-looped feature on Ethernet ports or v-ports. When the down-when-looped feature is activated, a keepalive loop PDU is transmitted periodically toward the network. The port listens for returning keepalive loop PDUs. A loop is detected if any of the received PDUs have an Ethertype value of 9000 and the source and destination MAC addresses are identical to the MAC address of the port. When a loop is detected, the port is immediately brought down.
Ethernet port-layer line loopbacks and Ethernet port-layer internal loopbacks can be enabled on the same port with the down-when-looped feature. EFM OAM cannot be enabled on the same port with the down-when-looped feature.
keep-alive
Syntax

the minimum wait time before re-enabling the Ethernet port or v-port
use-broadcast-address
Syntax
[no] use-broadcast-address
Context
config>port>ethernet>down-when-looped
Description
This command configures the down-when-looped feature to declare a loop when the destination MAC address matches the broadcast MAC address instead of the MAC address of the Ethernet port or v-port.
duplex
Syntax
duplex {full | half}
Context
config>port>ethernet
Description
This command configures the duplex mode of an Ethernet or Fast Ethernet port when autonegotiation is disabled.
The 10-port 1GigE/1-port 10GigE X-Adapter card must be in x10-1gb-sfp mode to support this command.
SFP slots hosting Ethernet or Fast Ethernet SFPs can be configured to full-duplex or half-duplex mode when autonegotiation is disabled. Duplex autonegotiation is automatically turned off when the user sets the mode with this command. SFP slots hosting optical GigE SFPs only support full-duplex mode; duplex autonegotiation is not supported.
On 10 Gb/s ports, the mode is always full duplex and cannot be changed. This includes the ring Ethernet XFP ports and the v-port on the 2-port 10GigE (Ethernet) Adapter card and 2-port 10GigE (Ethernet) module.
Default
full
efm-oam
Syntax
efm-oam
Context
config>port>ethernet
Description
This command configures EFM-OAM attributes.
accept-remote-loopback
Syntax
[no] accept-remote-loopback
Context
config>port>ethernet>efm-oam
Description
This command enables reactions to loopback control OAMPDUs from peers.
The no form of this command disables reactions to loopback control OAMPDUs.
Default
no accept-remote-loopback
hold-time
Syntax
hold-time time-value
no hold-time
Context
config>port>ethernet>efm-oam
Description
This command sets the amount of time that EFM-OAM will wait before going from a non-operational state to an operational state.
If EFM-OAM goes from an operational state to a non-operational state (other than link-fault), it enters the hold-time period. During this time, EFM-OAM continues to negotiate with the peer if possible, but will not transition to the ‟up” state until the hold time has expired.
If EFM-OAM goes down due to a lower-level fault (for example, the port goes down and EFM-OAM enters the link-fault state), the hold timer is not triggered. When the lower-level fault is cleared, EFM-OAM immediately starts running on the port and transitions to the operational state as soon as possible.
If EFM-OAM goes down because the user administratively disables the protocol, EFM-OAM immediately transitions to the disabled state. When the user re-enables EFM-OAM, the protocol enters the hold time period and EFM-OAM is not operational until the hold time expires.
A hold-time value of 0 indicates that EFM-OAM returns to the operational state without delay.
The hold time affects only the transition from a non-operational state to an operational state; it does not apply to a transition from an operational state to a non-operational state.
Default
no hold-time
Parameters
- time-value
the number of seconds that EFM-OAM will wait before returning to an operational state from a non-operational state
ignore-efm-state
Syntax
[no] ignore-efm-state
Context
config>port>ethernet>efm-oam
Description
This command decouples the EFM OAM protocol from the port state and operational state.
When this command is configured on the port, any failure in the EFM protocol state (discovery, configuration, time-out, loops, and so on) does not affect the port. Only a protocol warning message is raised to indicate issues with the protocol.
When the command is not configured on a port, the port state is affected by any EFM OAM protocol fault or clear condition.
If the port is a member of a microwave link, the ignore-efm-state command must be enabled before the EFM OAM protocol can be activated. This restriction is required because EFM OAM is not compatible with microwave links.
Default
no ignore-efm-state
mode
Syntax
mode {active | passive}
Context
config>port>ethernet>efm-oam
Description
This command configures the mode of OAM operation for this Ethernet port.
Active mode causes the port to initiate the negotiation process and continually send out efm-oam information PDUs. Passive mode waits for the peer to initiate the negotiation process. A passive mode port cannot initiate monitoring activities (such as loopback) with the peer.
Default
active
transmit-interval
Syntax
[no] transmit-interval interval [multiplier multiplier]
Context
config>port>ethernet>efm-oam
Description
This command configures the transmit interval of OAMPDUs.
Default
interval 10, multiplier 5
Parameters
- interval
specifies the transmit interval
- multiplier
specifies the multiplier for the transmit-interval to set the local link down timer
tunneling
Syntax
[no] tunneling
Context
config>port>ethernet>efm-oam
Description
This command enables EFM OAMPDU tunneling. OAMPDU tunneling is required when a loopback is initiated from a router end and must be transported over the existing network infrastructure to the other end. Enabling tunneling will allow the PDUs to be mapped to Epipes so that the OAM frames can be tunneled over MPLS to the far end.
To enable Ethernet EFM OAM 802.3ah on the port, use the efm-oam>no shutdown command.
The no form of the command disables tunneling.
Default
no tunneling
egress-rate
Syntax
egress-rate sub-rate [include-fcs] [allow-eth-bn-rate-changes] [hold-time hold-time]
no egress-rate
Context
config>port>ethernet
Description
This command configures the rate of traffic leaving the network.
With the include-fcs option, the egress rate limit is applied to the traffic rate egressing the port with the 4-byte Ethernet FCS field included. If this option is not configured, the egress rate limit is applied to the traffic rate egressing the port without the 4-byte Ethernet FCS field included, and the actual rate of packets leaving the port is slightly higher than the configured egress rate value.
The include-fcs option is not supported on the 7705 SAR-A Fast Ethernet ports (ports 9 to 12) or 4-port SAR-H Fast Ethernet module. On the 6-port SAR-M Ethernet module, the include-fcs option is always on and cannot be disabled to compensate for the 4-byte FCS.
The allow-eth-bn-rate-changes option enables the Y.1731 ETH-BN client MEP option on the port. In applications such as a point-to-point microwave link, where degradation on the line can result in reduced link bandwidth, the egress rate can be dynamically changed based on the available bandwidth on the link as indicated by the ETH-BN server. When enabled, the received rate overrides the configured sub-rate for the port. For information about ETH-BN, including which Ethernet ports support this functionality, see the 7705 SAR OAM and Diagnostics Guide, ‟ITU-T Y.1731 Ethernet Bandwidth Notification (ETH-BN)”.
The bandwidth indicated by the ETH-BN server includes the FCS; therefore, the include-fcs option must be selected if the allow-eth-bn-rate-changes option is selected or the dynamically changed bandwidth will not match the intended rate.
The hold-time is used to limit the number of bandwidth changes as requested by the ETH-BN server. After a rate change occurs based on a Bandwidth Notification Message (BNM), any BMN received before the hold timer expires will be ignored.
The no form of this command returns the value to the default.
Default
no egress-rate
Parameters
- sub-rate
the egress rate in kb/s
- include-fcs
the egress rate limit is applied to the traffic rate egressing the port with the 4-byte Ethernet FCS field included. This option must be selected if the allow-eth-bn-rate-changes option is selected; otherwise, the dynamically changed bandwidth will not match the intended rate.
- allow-eth-bn-rate-changes
enables the Y.1731 ETH-BN client MEP option on the port. The egress rate will be dynamically changed to the bandwidth indicated in messages received from an ETH-BN server MEP. When enabled, the received rate overrides the configured sub-rate for the port.
- hold-time
configures the hold time for egress rate bandwidth changes based on a received BNM, in seconds
encap-type
Syntax
encap-type {dot1q | null | qinq}
no encap-type
Context
config>port>ethernet
Description
This command configures the encapsulation method used to distinguish customer traffic on an Ethernet access port, network v-port, or different VLANs on a network port.
Before an MPR-e radio can be configured on an MWA port (see radio), the port must have an encapsulation type of dot1q.
The qinq encapsulation type is not supported by v-ports.
The no form of this command restores the default.
See also dot1q-etype and qinq-etype for information about tagging and encapsulation.
Default
null
Parameters
- dot1q
ingress frames carry 802.1Q tags, where each tag signifies a different service
- null
ingress frames will not use any tags to delineate a service. As a result, only one service can be configured on a port with a null encapsulation type.
- qinq
ingress frames carry two stacked tags, where the outer tag is the service provider tag and the inner tag is the customer service tag as defined in 802.1ad
group-encryption
Syntax
[no] group-encryption
Context
config>port>ethernet
Description
This command enables network group encryption (NGE) on the Ethernet port. When NGE is enabled on the port, all received Layer 2 IS-IS and LLDP packets are considered to be NGE packets and must be encrypted using a valid set of keys from any preconfigured key group on the system.
The no form of the command disables NGE on the Ethernet port. NGE cannot be disabled unless all key groups and IP exception filters are removed.
Default
no group-encryption
encryption-keygroup
Syntax
encryption-keygroup keygroup-id direction {inbound | outbound}
no encryption-keygroup direction {inbound | outbound}
Context
config>port>ethernet>group-encryption
Description
This command is used to bind a key group to an Ethernet port for inbound or outbound packet processing. When configured in the outbound direction, packets egressing the router use the active-outbound-sa associated with the configured key group. When configured in the inbound direction, received packets must be encrypted using one of the valid security associations configured for the key group.
The no form of the command removes the key group from the Ethernet port in the specified direction.
Default
no encryption-keygroup direction inbound
no encryption-keygroup direction outbound
Parameters
- keygroup-id
the ID number of the key group being configured
- inbound
binds the key group in the inbound direction
- outbound
binds the key group in the outbound direction
hold-time
Syntax
hold-time {[up hold-time-up] [down hold-time-down] [seconds | centiseconds]}
no hold-time
Context
config>port>ethernet
Description
This command configures port link dampening timers, which reduce the number of link transitions reported to upper layer protocols.
The hold-time value is used to dampen interface transitions.
When an interface transitions from an up state to a down state, interface down transitions are not advertised to upper layers until the hold-time-down interval has expired. When an interface transitions from a down state to an up state, interface up transitions are not advertised until the hold-time-up interval has expired.
If the hold-time-down or hold-time-up value is 0, interface down and interface up transitions are immediately reported to upper layer protocols.
The no form of this command reverts to the default values.
Default
down 0 or up 0 — no port link dampening is enabled; link transitions are immediately reported to upper layer protocols
Parameters
- hold-time-up
the interval, in seconds or centiseconds, before an interface transition from a down state to an up state is reported to upper layer protocols
- hold-time-down
the interval, in seconds or centiseconds, before an interface transition from an up state to a down state is reported to upper layer protocols
- seconds
- defines the time interval in seconds
- centiseconds
- defines the time interval in centiseconds
ingress-rate
Syntax
ingress-rate ingress-rate cbs size [bytes | kilobytes]
no ingress-rate
Context
config>port>ethernet
Description
This command configures a policing action to rate-limit the ingress traffic. Ingress-rate enforcement uses dedicated hardware for rate limiting, however software configuration is required at the port level (ingress-rate limiter) to ensure that the network processor or adapter card or port never receives more traffic than they are optimized for.
The configured ingress rate ensures that the network processor does not receive traffic greater than this configured value on a per-port basis. Once the ingress-rate value is reached, all subsequent frames are dropped. The ingress-rate limiter drops excess traffic without classifying whether the traffic has a higher or lower priority.
Similar to the egress-rate configuration, the ingress-rate configuration survives port mode changes. If a port mode is changed (for example, from access to network mode), the ingress rate and configured CBS still remain when the port comes back up.
The no form of this command returns the value to the default.
Default
no ingress-rate
Parameters
- ingress-rate
the ingress rate in Mb/s
- cbs
specifies the committed burst size that the hard policer can accept while complying with the configured ingress rate. Set the cbs value to at least two times the ingress packet size so that the datapath can make a proper policing and forwarding decision.
Note: CBS is integrated with the ingress-rate command and you must always specify the CBS size every time you configure the ingress rate. If you use the default CBS size, you must explicitly indicate that it is the CBS default.
- size
specifies the committed burst size in bytes or kilobytes. If configured in bytes, the committed burst size must be a multiple of 256 bytes and must include the bytes parameter. If configured in kilobytes, the maximum value is 127 and must include the kilobytes parameter. If configured as default, the value is set to 130816 bytes.
src-pause
Syntax
src-pause
no src-pause
Context
config>port>ethernet>ingress-rate
Description
This command sends a notification to slow down the transmission rate when it exceeds the bandwidth limit.
If incoming traffic exceeds the configured ingress rate, an src-pause frame is sent to the far end to hold transmission (src-pause delay timer). When the src-pause delay timer expires, the far end resumes transmission. The src-pause delay timer varies based on the difference between the incoming traffic rate and the configured ingress rate on the port. If the difference is large, then the far end must wait for a longer period before resuming transmission. The src-pause frame helps to prioritize far-end traffic so that the ingress-rate limiter does not drop high-priority traffic.
The ingress-rate limiter can be configured with or without src-pause; however, src-pause is disabled whenever the ingress-rate limiter is disabled.
The no form of this command disables the src-pause feature.
This command is blocked for the 6-port SAR-M Ethernet module.
Default
no src-pause
lacp-tunnel
Syntax
lacp-tunnel
no lacp-tunnel
Context
config>port>ethernet
Description
This command enables LACP packet tunneling for the Ethernet port. When tunneling is enabled, the port does not process any LACP packets, but tunnels them instead. A port with LACP packet tunneling enabled cannot be added as a member of a Link Aggregation Group (LAG).
The no form of this command disables LACP packet tunneling for the Ethernet port.
Default
no lacp-tunnel
loopback
Syntax
loopback {line | internal} {timer {0 | 30 .. 86400} | persistent} [swap-src-dst-mac]
no loopback
Context
config>port>ethernet
Description
This command configures timed line loopbacks on Ethernet network and access ports, timed line loopbacks on ring Ethernet network ports, untimed line loopbacks on Ethernet access ports, and timed and untimed internal loopbacks on Ethernet ports.
For Ethernet ports, a line loopback loops frames received on the corresponding port back towards the transmit (egress) direction inside the network processor. Line loopbacks are supported on ports configured in network or access mode.
You can swap the source and destination MAC addresses of the received frames using the swap-src-dst-mac keyword. The swap-src-dst-mac keyword is not supported on ring Ethernet ports.
An internal loopback loops the frames that are coming in an egress direction from the fabric towards the framer, back to the fabric. This type of loopback is usually referred to as an equipment loopback. Internal loopbacks are supported on ports configured in access mode.
Loopback timers can be configured for 30 s to 86400 s. All non-zero timed loopbacks are turned off under the following conditions: an adapter card reset, an activity switch, or timer expiry. Line or internal loopbacks can also be configured as a latched loopback by setting the timer to 0 s, or as a persistent loopback with the persistent keyword.
Latched and persistent loopbacks are enabled indefinitely until turned off by the user. Latched loopbacks survive adapter card resets and activity switches, but are lost if there is a system restart. Persistent loopbacks survive adapter card resets and activity switches and can survive a system restart if the admin-save or admin-save-detail command was executed prior to the restart. Latched (untimed) persistent loopbacks can be enabled only on Ethernet access ports.
If a loopback exists on a port, it must be disabled or the timer must expire before another loopback can be configured on the same port. An Ethernet loopback cannot be configured on a port that has EFM-OAM enabled on it; EFM-OAM cannot be enabled on a port that has an Ethernet loopback enabled on it.
Persistent loopbacks are the only Ethernet loopbacks saved to the database by the admin-save and admin-save-detail commands.
The no form of this command disables the specified type of loopback.
Parameters
- line
places the associated Ethernet port or ring Ethernet port into line loopback mode
- internal
places the associated Ethernet access port into internal loopback mode; not supported on ring Ethernet ports
- persistent
places the associated Ethernet access port or ring Ethernet port into persistent loopback mode
- swap-src-dst-mac
swaps source and destination MAC addresses for Ethernet line loopbacks; not supported on ring Ethernet ports
- timer
the timer set for Ethernet loopbacks, in seconds
mac
Syntax
mac ieee-address
no mac
Context
config>port>ethernet
Description
This command assigns a specific MAC address to an Ethernet port, ring Ethernet port, or v-port. When the command is issued while the port is operational, IP will issue an ARP, if appropriate, and BPDUs are sent with the new MAC address.
The no form of this command returns the MAC address to the default value.
Default
a default MAC address is assigned by the system
Parameters
- ieee-address
specifies the 48-bit MAC address in the form aa:bb:cc:dd:ee:ff or aa-bb-cc-dd-ee-ff where aa, bb, cc, dd, ee, and ff are hexadecimal numbers. Allowed values are any non-broadcast, non-multicast MAC, and non-IEEE reserved MAC addresses.
mode
Syntax
mode {access | network | hybrid}
no mode
Context
config>port>ethernet
Description
This command configures an Ethernet port for access, network, or hybrid mode operation, or configures a ring Ethernet port or v-port for network mode. On ring Ethernet ports and the v-port, the mode is always network and cannot be changed.
An access port is used for customer-facing traffic on which services are configured. A Service Access Point (SAP) can only be configured on an access port or channel. Once an Ethernet port has been configured for access mode, multiple services can be configured on it.
A network port participates in the service provider transport or infrastructure network when network mode is selected.
A hybrid Ethernet port allows the combination of network and access modes of operation on a per-VLAN basis and must be configured for either dot1q or qinq encapsulation.
A hybrid port must use dot1q encapsulation to be configured as a network IP interface. Binding a network IP interface to a qinq encapsulation is blocked. In hybrid mode, qinq encapsulation is for access mode use only.
If the hybrid port is configured for dot1q encapsulation, the user configures a SAP inside a service or a network IP interface as follows:
configure a SAP under config>service by providing the SAP ID, which must include the port-id value of the hybrid port and an unused VLAN tag value. The format is port-id:qtag1. A SAP of format port-id:* is also supported.
configure a network IP interface under config>router>if>port by providing the port-name, which consists of the port-id of the hybrid port and an unused VLAN tag value. The format is port-id:qtag1. The user must explicitly enter a valid value for qtag1. The port-id:* value is not supported on a network IP interface. The VLAN tag space on the port (range of 0 to 4094) is shared among VLAN SAPs and VLAN network IP interfaces.
If the hybrid port is configured for qinq encapsulation, the user configures a SAP inside a service as follows:
configure a SAP under config>service by providing the SAP ID, which must include the port-id value of the hybrid port and the outer and inner VLAN tag values. The format is port-id:qtag1.qtag2. A SAP of format port-id: qtag1.* is also supported. The outer VLAN tag value must not have been used to create an IP network interface on this port. In addition, the qtag1.qtag2 value combination must not have been used by another SAP on this port.
The no form of this command restores the default.
Default
access (except as listed below)
network
10-port 1GigE/1-port 10GigE X-Adapter card (in 1-port 10GigE mode, the port operates in network mode only)
2-port 10GigE (Ethernet) Adapter card
2-port 10GigE (Ethernet) module
Parameters
- access
configures the port as service access
- network
configures the port for transport network use
- hybrid
configures the port for hybrid use (transport network and service access per VLAN)
mtu
Syntax
mtu mtu-bytes
no mtu
Context
config>port>ethernet
Description
This command configures the maximum payload MTU size for an Ethernet port or a v-port on an Ethernet Ring adapter card (for ring Ethernet ports, the MTU value is fixed at 9728 bytes).
The port-level MTU parameter indirectly defines the largest physical packet the port can transmit or the far-end Ethernet port can receive. Packets to be transmitted over a given port that are larger than the MTU of the port will be fragmented or discarded, depending on whether the DF bit is set in the packet header.
If the port mode or encapsulation type is changed, the MTU assumes the default values of the new mode or encapsulation type.
The no form of this command restores the default values.

Notes:
- The maximum MTU value is supported only on cards that have buffer chaining enabled.
- On the Packet Microwave Adapter card, MWA ports support 4 bytes less than Ethernet ports. MWA ports therefore support a maximum MTU of 9720 bytes (null) or 9724 bytes (dot1q). MWA ports do not support qinq.
- QinQ is supported only on access ports.
Default
The default MTU value depends on the port type, mode, and encapsulation as listed in Port MTU Default and Maximum Values .
Parameters
- mtu-bytes
sets the maximum allowable size of the MTU, expressed as an integer (see Port MTU Default and Maximum Values )
phy-tx-clock
Syntax
[no] phy-tx-clock {auto-pref-master | auto-pref-slave | slave | master}
Context
config>port>ethernet
Description
This command configures the 1000Base-T physical layer transmit clock. The mode affects the establishment of the master-slave relationship between two ports sharing a link segment during auto-negotiation. The master port uses a local clock to determine the timing of transmitter operations. The slave port recovers the clock from the signal it receives and uses the signal to determine the timing of transmitter operations. For ports that do not support 1000Base-T, the value defaults to N/A and cannot be changed.
The phy-tx-clock configuration is supported on SFP ports whether or not the SFP is inserted. The phy-tx-clock command applies only to copper-based RJ45 synchronous Ethernet ports. The command can be used on an SFP port that supports fiber and copper, but the command has no effect if a fiber SFP is installed.
The proper value must be set to ensure that the synchronous Ethernet clock relay is correctly configured. See the 7705 SAR Basic System Configuration Guide for more information about synchronous Ethernet.
Default
The default value for the MWA 1000Base-T Ethernet ports on the Packet Microwave Adapter card is master. On other adapter cards, the default value is auto-pref-slave for ports that support 1000Base-T Ethernet connections. The default value is n/a for ports that do not support 1000Base-T Ethernet connections.
Parameters
- auto-pref-master
prefers to be master during autonegotiation
- auto-pref-slave
prefers to be slave during autonegotiation
- slave
forces the port to be the slave clocking source
- master
forces the port to be the master clocking source
poe
Syntax
poe [plus]
no poe
Context
config>port>ethernet
Description
The poe command enables an RJ45 or RJ point five port that is Power over Ethernet (PoE) capable to deliver power to a ‟Powered Device” at levels compatible with the IEEE 802.3af standard.
The poe plus command enables an RJ45 or RJ point five port that is PoE+ capable to deliver power to a ‟Powered Device” at levels compatible with the IEEE 802.3at standard.
On the 7705 SAR-H, 7705 SAR-Hc, and 6-port SAR-M Ethernet module, a PoE-capable port can be configured for PoE and PoE+. On the 7705 SAR-Wx, a PoE-capable port only supports PoE+ and can only be enabled using the poe plus command.
On the 7705 SAR-H, before a port can be configured for either PoE or PoE+, the PoE power source option must first be configured as either internal or external using the config>system>poe-power-source command; see the 7705 SAR Basic System Configuration Guide, ‟System Command Reference”, for information.
When the 7705 SAR-H is configured for the internal power source option, PoE capability is allowed on ports 5 and 6 only. Port 5 can be configured for PoE+ but in that case, port 6 cannot support PoE. When the system is configured for the external power source option, a mix of PoE and PoE+ is allowed on ports 5, 6, 7, and 8. PoE+ is supported only on ports 5 and 7. Supported PoE/PoE+ Combinations on the 7705 SAR-H describes the allowed mix of PoE and PoE+ ports on the 7705 SAR-H.

On the 6-port SAR-M Ethernet module, ports 5 and 6 on the module can each support PoE. Port 5 can also support PoE+, but if it is configured for PoE+, then port 6 cannot support PoE power.
On the 7705 SAR-Hc, ports 5 and 6 each support PoE and PoE+. If configured for PoE, both ports can be used for PoE simultaneously. Both ports are also capable of supporting PoE+ but not simultaneously; if one port is configured for PoE+, the other port can only be configured for PoE. Ports 5 and 6 can also operate in non-PoE mode.
On the 7705 SAR-Wx, port 5 (the RJ45 port labeled PoE) supports PoE+. The port can also operate in non-PoE+ mode.
To disable PoE/PoE+ on a port and prevent it from delivering power, use the no form of the command. Performing a shutdown command on the port does not disable PoE/PoE+ on the port.
Default
n/a
Parameters
- plus
enables PoE+ on the 7705 SAR-H, 7705 SAR-Hc, 7705 SAR-Wx, and 6-port SAR-M Ethernet module
ptp-asymmetry
Syntax
ptp-asymmetry ptp-asymmetry
no ptp-asymmetry
Context
config>port>ethernet
Description
This command configures the PTP asymmetry delay delta on an Ethernet port. The command corrects for known asymmetry for time of day/phase recovery of PTP packets on both local and downstream PTP slave clocks as well as on end-to-end transparent clocks.
Parameters
- ptp-asymmetry
the value in nanoseconds that the forward path delay varies from the mean path delay; the value can be a negative number
qinq-etype
Syntax
qinq-etype 0x0600 to 0xffff
no qinq-etype
Context
config>port>ethernet
Description
This command specifies the Ethertype expected when the port’s encapsulation type is qinq. The qinq-etype value sets the Ethertype for the outer VLAN tag when qinq encapsulation is used.
IEEE 802.1ad (also known as VLAN stacking) defines a process to channelize a single Ethernet port or v-port into double-tagged VLANs. Each VLAN can represent a customer or an application. Each tag allows for up to 4096 VLANs to be configured on a port (4096 ✕ 4096 total). For more information about VLANs and VLAN tagging, see ‟VLL Services” in the 7705 SAR Services Guide.
The Ethertype specifies the protocol being carried in an Ethernet frame. In 802.1q, the Ethertype is set to the Tag Protocol Identifier (TPID) value of 0x8100, which identifies the frame as an IEEE 802.1Q-tagged frame. As well, 2 bytes of Tag Control Information (TCI), followed by 2 bytes containing the frame’s original Ethertype are added to the frame for each tag (4 bytes total). Together, the TPID and TCI make up a VLAN tag.
The qinq-etype command is not supported by v-ports.
Network ports do not allow qinq-etype settings.
The no form of this command resets the qinq-etype value to the default.
Default
0x8100
Parameters
- 0x0600 to 0xffff
specifies the Ethertype to expect
report-alarm
Syntax
[no] report-alarm [signal-fail] [remote] [local] [no-frame-lock] [high-ber]
Context

Ring MAC Operations Commands
disable-aging
Syntax
[no] disable-aging
Context
config>card>mda>ring
Description
This command disables MAC address aging across an Ethernet ring.
As is the case for a Layer 2 switch, learned MACs can be aged out if no packets are sourced from the MAC address for a period of time (the aging time). In each ring, there are independent aging timers for local learned MAC and remote learned MAC entries in the FDB. The disable-aging command turns off aging for local and remote learned MAC addresses.
The no form of this command enables aging on the ring.
Default
no disable-aging
disable-learning
Syntax
[no] disable-learning
Context
config>card>mda>ring
Description
This command disables learning of new MAC addresses in the ring FDB.
When disable-learning is enabled, new source MAC addresses will not be entered in the ring FDB. This is true for both local and remote MAC addresses.
When disable-learning is disabled, new source MAC addresses will be learned and entered into the ring FDB.
This parameter is mainly used in conjunction with the discard-unknown-source command.
The no form of this command enables learning of MAC addresses.
Default
no disable-learning
discard-unknown-source
Syntax
[no] discard-unknown-source
Context
config>card>mda>ring
Description
This command specifies that packets with an unknown source MAC address received on a ring port will be dropped if the source MAC is not already in the FDB (that is, the source MAC was not learned before the discard-unknown-source command was enabled or is not a static entry already created for the packet MAC).
When disabled, the packets are flooded to the other ring port or forwarded to the v-port (if the packets are addressed to the v-port).
The no form of this command disables discard-unknown-source.
Default
no discard-unknown-source

the maximum number of learned MAC entries in the FDB for the ring
mac-pinning
Syntax
[no] mac-pinning port port-id
Context
config>card>mda>ring
Description
This command keeps MAC address information that has been learned from a source frame in the FDB until the expiry of the mac-aging timer, which is specified using the remote-age command). If a MAC address is pinned and a frame with an existing source MAC address is received from the other ring port, the FDB entry is not altered—the address that was learned from the first source frame is preserved until the expiry of the aging timer. If the aging timer is disabled, then the MAC address remains pinned until the timer is enabled again.
The no form of this command disables mac-pinning.
Default
no mac-pinning
Parameters
- port-id
specifies the physical ring port
remote-age
Syntax
remote-age aging-timer
no remote-age
Context
config>card>mda>ring
Description
This command specifies the aging time for remotely learned MAC addresses in the FDB.
As is the case for a Layer 2 switch, learned MAC addresses can be aged out if no packets are sourced from the MAC address for a period of time (the aging time). The remote-age timer specifies the aging time for remotely learned MAC addresses.
The no form of this command returns the remote aging timer to the default value (900 s).
Default
no remote-age
Parameters
- aging-timer
the aging time for remote MAC addresses, expressed in seconds
static-mac
Syntax
[no] static-mac mac ieee-address port port-id [create]
Context
config>card>mda>ring
Description
This command creates a local static MAC entry in the FDB for the specified port. The maximum number of static MAC addresses per ring adapter card is 256.
Static MAC definitions on one edge device are not propagated to other edge devices; that is, each edge device has an independent FDB.
Only one static MAC entry (local or remote) can be defined per MAC address per instance.
By default, no static MAC address entries are defined.
The no form of this command deletes the static MAC entry with the specified MAC address associated with the port from the FDB.
Parameters
- ieee-address
specifies the 48-bit MAC address for the static ARP in the form aa:bb:cc:dd:ee:ff or aa-bb-cc-dd-ee-ff where aa, bb, cc, dd, ee and ff are hexadecimal numbers (cannot be all zeros). Allowed values are any non-broadcast, non-multicast MAC, and non-IEEE reserved MAC addresses.
- port-id
specifies the port that is associated with the specified MAC address
- create
this keyword is mandatory when specifying a static MAC address
Serial Commands
serial
Syntax
serial
Context
config>port
Description
This command enables the context to configure RS-232, V.35, X.21, or RS-530 parameters for a port on a channelized 12-port Serial Data Interface card, or to configure RS-232 parameters for an RS-232 port on the 7705 SAR-Hc or on the 4-port T1/E1 and RS-232 Combination module. This context cannot be accessed by any other adapter card, module, or platform.
On the 12-port Serial Data Interface card version 2, if the port has been enabled for an RS-530 interface through the use of an adapter cable, X.21 configuration applies to the RS-530 interface. There is no configuration specifically for RS-530 operation on this card version. For the 12-port Serial Data Interface card, version 3, there is a separate rs530 command to configure RS-530 channel parameters.
A serial port configuration allows some or all of the bandwidth to be dedicated to a port by aggregating a number of DS0s into a single bundle.
Serial data transmission rates below the rate of a single DS0, that is, less than 64 kb/s, are achieved using a proprietary protocol called High Capacity Multiplexing (HCM). These speeds, known as subrate speeds, are supported on RS-232, X.21, and RS-530 ports.

Context
config>port>serial
Description
This command enables the context to configure X.21 parameters for a channel. When one of the ports on a connector has been configured for an X.21 channel, the other ports on the connector can only be configured for X.21.
On a 12-port Serial Data Interface card version 2, if the port has been enabled for an RS-530 interface through the use of an adapter cable, X.21 configuration applies to the RS-530 interface. There is no configuration specifically for RS-530 operation. All X.21 functionality is available on the RS-530 interface, except that only DCE operation is supported for RS-530. However, because X.21 does not support all the control leads available for RS-530, only a subset of the RS-530 control leads are supported.
The no form of this command deletes the X.21 channel.

Syntax
device-gender {dte | dce}
Context
config>port>serial>rs232
config>port>serial>rs530
config>port>serial>v35
config>port>serial>x21
Description
This command configures the gender of the device.
Data and control signals are transmitted and received over wire pairs. The gender of a device indicates which wire in the pair is used to send and receive the signal.
On ports on the 12-port Serial Data Interface card, version 2, the data and control signals are electrically wired as DCE. Regardless of the gender configured, the Tx pin on the port is always an input pin and the Rx pin on the port is always an output pin. Changing a port from DCE to DTE does not change the pin orientation. Therefore, when a port is configured as DTE, a crossover cable is required in order to interconnect with some serial devices. If the port has been enabled for an RS-530 interface through the use of an adapter cable, only DCE operation is supported.
Default
dce
Parameters
- dte
the device is performing the role of the data terminal equipment
- dce
the device is performing the role of the data communications equipment

config>port>serial>v35
config>port>serial>x21
Description
This command puts the specified interface into a loopback mode. The corresponding interface must be in a shutdown state in order for the loopback mode to be enabled.
In the serial context, a bidirectional loopback B or E can be configured. A bidirectional loopback is a circuit loopback that loops traffic from the line back to the line and simultaneously loops traffic from the system back to the system. Bidirectional loopback B takes place on the control card (CSM) side of the adapter card, and is closer to the system. Loopback E takes place on the data device side of the adapter card, and is closer to the line.
This command is not saved in the system configuration between boots.
The no form of this command disables loopback on the interface.
Default
no loopback
Parameters
- bidir-b
specifies that the loopback is bidirectional loopback B (not supported on the 12-port Serial Data Interface card, version 3)
- bidir-e
specifies that the loopback is bidirectional loopback E
- bidir-e-signalling
- specifies that the loopback is bidirectional loopback E and is looping the internal signaling; this option is only supported on RS-530 interfaces

multi-drop
Syntax
multi-drop {disabled | slave | master}
Context
config>port>serial>rs232
config>port>serial>rs530
config>port>serial>x21
Description
This command configures the multidrop data bridge (MDDB) mode. MDDB is a polling scheme used on SCADA networks (supervisory or control systems used in utility, oil and gas, and other vertical applications) to communicate with multiple remote terminal units (RTUs) over a single RS-232, RS-530, or X.21 link.
In an MDDB, several circuits take turns using the same bandwidth to communicate with one circuit. Each slave device transmits data in that bandwidth when requested by the master device. The master device sends polling messages to, and looks for data from, the slave devices in that bandwidth.
One example of a multidrop data bridge is several terminals taking turns to communicate with a host computer. The circuit that all the other circuits communicate with is connected to a master device (a computer) and is designated the master; the rest of the circuits are connected to slave devices (terminals) and are designated slaves.
In a SCADA network, the 7705 SAR provides the communications infrastructure to connect the central masters to multiple RTUs at remote locations, where the masters and RTUs communicate over serial RS-232 and X.21 synchronous or asynchronous links, or serial RS-530 asynchronous links (RS-530 links are only supported on the 12-port Serial Data Interface card, version 3). The 7705 SAR-8 Shelf V2 or 7705 SAR-18 located at the master site contains the Integrated Services card, which provides the MDDB bridge functionality and acts as the MDDB master. Remote 7705 SAR nodes connected to RTUs are referred to as MDDB slaves.
For both master and slave applications, the 7705 SAR must be physically connected to the SCADA device by one of the following:
a 7705 SAR-8 Shelf V2 or 7705 SAR-18 using the 12-port Serial Data Interface card
a 7705 SAR-H using the 4-port T1/E1 and RS-232 Combination module (supports RS-232 links only)
a 7705 SAR-Hc using an on-board RS-232 serial port (supports RS-232 links only)
Multidrop data bridge is supported only at subrate speeds (less than 64 kb/s) on X.21 interfaces.
When an RS-232 interface is configured as an MDDB slave, the duplex mode is automatically set to half-duplex and s-bit-signaling is forced off. When multidrop data bridge is disabled, the duplex mode is set back to the default of full-duplex and S-bit signaling is turned on (but can be set back to off).
When either an RS-232, RS-530, or X.21 interface is configured as an MDDB master, the duplex mode is automatically set to full-duplex and S-bit signaling is forced off.
Default
disabled
Parameters
- disabled
MDDB mode is off
- slave
the port is operating as an MDDB slave device
- master
the port is operating as an MDDB master device
parity

Description
This command configures the parity bit in a character. Parity is an error detection method that adds an extra bit to each character, based on the number of 0s or 1s in the character.
This command is valid only if device-mode is asynchronous. The value for this command must be no parity (that is, none) if the character-length value is 8 and the stop-bits value is 2.
The no form of this command disables the parity bit in a character.
Default
no parity
Parameters
- odd
the parity bit is set to 0 or 1 to make the total number of 1s in the set of bits odd
- even
the parity bit is set to 0 or 1 to make the total number of 1s in the set of bits even
- mark
the parity bit is present but not used and is always set to 1
- space
the parity bit is present but not used and is always set to 0

config>port>serial>x21
Description
This command configures the S-bit signaling option on an RS-232, RS-530, or X.21 interface.
For RS-232 interfaces only, if multi-drop is configured as slave or master, the system automatically turns S-bit signaling off. The signaling mode cannot then be changed. If multi-drop is configured as disabled, the system automatically turns S-bit signaling on. When multi-drop is in disabled mode, S-bit signaling can be turned off or on.
This command is only valid for ports configured for subrate speeds.
Default
on
Parameters
- on
enables S-bit signaling
- off
disables S-bit signaling

Description
This command activates a loopback on the SONET/SDH port. The SONET port must be in a shutdown state to activate any type of loopback. The loopback setting is never saved to the generated/saved configuration file.
Default
no loopback
Parameters
- line
-
sets the port into a line loopback state. A line loopback loops frames received on the corresponding port back toward the transmit (egress) direction. Line loopbacks are supported on ports configured in network mode.
- internal
-
sets the port into an internal loopback state. An internal loopback loops the frames that are coming in an egress direction from the fabric toward the framer, back to the fabric. This type of loopback is usually referred to as an equipment loopback. Internal loopbacks are supported on ports configured in access mode.
report-alarm
Syntax
[no] report-alarm [loc] [lais] [lrdi] [ss1f] [lb2er-sd] [lb2er-sf] [slof] [slos] [lrei]
Context
config>port>sonet-sdh
Description
This command enables logging of SONET/SDH line and section alarms for a SONET/SDH port. When configured, logging is enabled for the raising and clearing of the specified alarms.

section-trace
Syntax
section-trace {increment-z0 | byte value | string string}
Context
config>port>sonet-sdh
Description
This command configures the section trace bytes in the SONET section header to interoperate with some older versions of ADMs or regenerators that require an incremental STM ID. You can explicitly configure an incremental STM value rather than a static one in the SDH overhead by specifying an increment-z0 value.
The increment-z0 parameter is not supported on the 4-port OC3/STM1 / 1-port OC12/STM4 Adapter card.
Default
byte 0x1
Parameters
- increment-z0
configures an incremental STM ID instead of a static value
- value
sets values in SONET header bytes
- string
specifies a text string that identifies the section
speed
Syntax
speed {oc3 | oc12}
Context
config>port>sonet-sdh
Description
This command configures the speed of a SONET/SDH port.
Although the oc3 option is shown in the CLI, it is not configurable. And, although the oc12 option is shown in the CLI, it is not available for use on the 7705 SAR. Users can change between oc3 and oc12 on the 4-port OC3/STM1 / 1-port OC12/STM4 Adapter card by using the mda-mode keyword in the config>card>mda context and selecting either the p4-oc3 or p1-oc12 option. The adapter card automatically reboots to make the change.
The no form of this command reverts to the default value.
Default
oc3
Parameters
- oc3
sets the speed of the port to OC3
- oc12
sets the speed of the port to OC12 (not available on the 7705 SAR)
threshold
Syntax
threshold {ber-sd | ber-sf} rate threshold-rate
no threshold {ber-sd | ber-sf}
Context
config>port>sonet-sdh
Description
This command configures the line signal (b2) degradation bit error rate (BER) and line signal failure thresholds.
Alarms are raised if the line signal bit interleaved parity error rates exceed either the degradation or failure thresholds. If the failure threshold is crossed, the link will be set to operationally down.
The no form of this command reverts to the default value.
Default
threshold ber-sd 6 - signal degrade BER threshold of 10-6
threshold ber-sf 3 - signal failure BER threshold of 10-3
Parameters
- ber-sd
specifies the BER for signal degradation
- ber-sf
specifies the BER for signal failure
- threshold-rate
specifies the BER negative exponent (n in 10-n), expressed as a decimal integer
tx-dus
Syntax
[no] tx-dus
Context
config>port>sonet-sdh

Default
no tx-dus
SONET/SDH Path Commands
path
Syntax
[no] path [sonet-sdh-index]
Context
config>port>sonet-sdh
Description
This command defines the SONET/SDH path.
The no form of this command removes the specified SONET/SDH path.
Default
no index is specified
Parameters
- sonet-sdh-index
specifies the components making up the SONET/SDH path. Depending on the SONET/SDH adapter card and the type of SONET/SDH port, the sonet-sdh-index must specify one or more path indexes to identify the payload location of the path. The CLI uses the same sonet-sdh-index syntax nomenclature to configure SONET and SDH paths.
In addition, the support of virtual tributary circuits adds another level of complexity and several levels of indexes, which means that one or more path commands may be needed to set up the container in the path.
On the 4-port OC3/STM1 Clear Channel Adapter card, sonet-sdh-index is optional; if used, the value must be sts3.
crc
Syntax
crc {16 | 32}
Context
config>port>sonet-sdh>path
Description
This command specifies a cyclic redundancy check on a SONET/SDH path on a SONET/SDH port.
Default
32 (if the encap-type is set to atm; this default cannot be changed)
16 (if the encap-type is set to ppp-auto; port is configured for POS)
Parameters
- 16
specifies that a 16-bit checksum be used for the associated port/channel
- 32
specifies that a 32-bit checksum be used for the associated port/channel
encap-type
Syntax
encap-type {atm | ppp-auto}
Context
config>port>sonet-sdh>path
Description
This command configures the encapsulation method used to distinguish customer traffic on a SONET/SDH path on a SONET/SDH port.
The encap-type of atm is used for access mode (4-port OC3/STM1 Clear Channel Adapter card and 2-port OC3/STM1 Channelized Adapter card), and the encap-type of ppp-auto is used for network mode (4-port OC3/STM1 / 1-port OC12/STM4 Adapter card).
When encap-type is atm, the crc default of 32 cannot be changed.
When encap-type is atm, ATM sublayer verification specified in GR-1248-CORE, Generic Requirements for Operations of ATM Network Elements, is automatically enabled. The result of the verification includes:
Out of Cell Delineation (OCD) event count — the OCD event count is described in RFC 2515, Definitions of Managed Objects for ATM Management. Multiple events occurring within 1 s will be counted as one event for ATM and ASAP adapter cards as a result of a hardware limit.
Loss of Cell Delineation (LCD) defect/alarm — the LCD defect/alarm is defined in RFC 2515, Definitions of Managed Objects for ATM Management. When a path is in an LCD defect state, the path’s operational status is down. When a path exits the LCD state, the path’s operational status will change to up (assuming nothing else causes the path to stay down). A trap is raised to indicate the LCD status change, and a Path Remote Defect Indicator (PRDI) is sent to indicate the defect to the remote end.
To change the encap-type, the path must first be removed and then recreated with the new encap-type. For example, to change the encap-type from atm to ppp-auto:
- CLI Syntax:
-
config>port>sonet-sdh>path# back config>port>sonet-sdh# no path config>port>sonet-sdh# path config>port>sonet-sdh>path# mode network config>port>sonet-sdh>path# encap-type ppp-auto config>port>sonet-sdh>path#
Default
no encap-type
Parameters
- atm
specifies that the encapsulation on the port is ATM
- ppp-auto
enables PPP on the associated port or channel. The activation of IPCP and MPLSCP is automatic depending on the protocol configuration.
mode
Syntax
mode {access | network}
Context
config>port>sonet-sdh>path
Description
This command configures the mode of operation for a SONET/SDH port or channel on a 4-port OC3/STM1 Clear Channel Adapter card or 4-port OC3/STM1 / 1-port OC12/STM4 Adapter card.
An access port or channel is used for customer-facing traffic on which services are configured. A Service Access Point (SAP) can only be configured on an access port or channel. When a port or channel on the 4-port OC3/STM1 Clear Channel Adapter card is configured for access mode, the encap-type must be set to atm. The 4-port OC3/STM1 / 1-port OC12/STM4 Adapter card does not support ATM when configured for access mode.
A network port or channel configured for Packet over SONET (POS) is used as an uplink to connect to the packet network and transport the configured services. When a port or channel is configured for network mode, the encap-type must be set to ppp-auto.
To change the mode, the path must first be removed and then recreated with the new mode. For example, to change the mode from access to network:
- CLI Syntax:
-
config>port>sonet-sdh>path# back config>port>sonet-sdh# no path config>port>sonet-sdh# path config>port>sonet-sdh>path# mode network config>port>sonet-sdh>path#

scramble
Syntax
[no] scramble
Context
config>port>sonet-sdh>path
Description
This command enables SONET/SDH payload scrambling on a 4-port OC3/STM1 Clear Channel Adapter card.
Scrambling randomizes the pattern of 1s and 0s carried in a SONET frame. Scrambling, or rearranging, the pattern prevents continuous strings of all 1s or all 0s and meets the needs of physical layer protocols that rely on sufficient transitions between 1s and 0s to maintain clocking.
For ATM, this command enables or disables ATM cell-level payload scrambling or descrambling using the x43+1 polynomial as defined in ITU-T I.432.1. Scrambling is enabled by default for the ATM path or channel. This scrambling is done in addition to SONET/SDH frame scrambling or descrambling, which is always enabled in the framer.
The no form of this command disables scrambling.
Default
scramble
signal-label
Syntax
signal-label value
no signal-label
Context
config>port>sonet-sdh>path
Description
This command sets the C2 byte value. The purpose of this byte is to communicate the payload type being encapsulated by SONET framing.
Default
0xcf
Parameters
- value
specifies the C2 byte value, expressed as a decimal integer or a hexadecimal value
trace-string
Syntax
trace-string [trace-string]
no trace-string
Context
config>port>sonet-sdh>path
Description
This command specifies the path trace identifier for the circuit that is continuously inserted at source. This identifier corresponds to J1 or J2 in the SONET/SDH overhead, depending on the associated path. The specified trace string can be checked against the expected value by the receiver. If no trace string is entered, a null string is used.
The no form of this command resets the string to its default.
Default
The default path trace value is ALU 7705 SAR. The value does not change when the encap-type changes. The path trace string contains all zeros for a non-provisioned path.
Parameters
- trace-string
specifies an alphanumeric string value. If the string contains spaces, enclose it in quotation marks.

accounting-policy
Syntax
accounting-policy policy-id
no accounting-policy
Context
config>port>ethernet>network
config>port>sonet-sdh>path>network
config>port>tdm>ds1>channel-group>network
config>port>tdm>ds3>network
config>port>tdm>e1>channel-group>network
config>port>tdm>e3>network
Description
This command configures an accounting policy that can apply to an interface.
An accounting policy must be configured before it can be associated to an interface. If the accounting policy-id does not exist, an error is returned.
Accounting policies associated with service billing can only be applied to SAPs. Accounting policies associated with network ports can only be associated with interfaces. Only one accounting policy can be associated with an interface at a time.
No accounting policies are specified by default. You must explicitly specify a policy. If configured, the accounting policy configured as the default under the config>log>accounting-policy>default command is used.
The no form of this command removes the accounting policy association from the network interface, and the accounting policy reverts to the default.
Default
n/a
Parameters
- policy-id
specifies the accounting policy-id of an existing policy. Accounting policies record either service (access) or network information. A network accounting policy can only be associated with the network port configurations. Accounting policies are configured in the config>log>accounting-policy context.
collect-stats
Syntax
[no] collect-stats
Context
config>port>ethernet>network
config>port>sonet-sdh>path>network
config>port>tdm>ds1>channel-group>network
config>port>tdm>ds3>network
config>port>tdm>e1>channel-group>network
config>port>tdm>e3>network
Description
This command enables the collection of accounting and statistical data for the network interface. When applying accounting policies, the data, by default, is collected in the appropriate records and written to the designated billing file.
When the no collect-stats command is issued, the statistics are still accumulated by the adapter cards. However, the CPU does not obtain the results and write them to the billing file. If the collect-stats command is issued again (enabled), then the counters written to the billing file will include the traffic collected while the no collect-stats command was in effect.
Default
no collect-stats
egress
Syntax
egress
Context
config>port>ethernet>network
Description
This command enables access to the context to assign network egress parameters.
Default
n/a
shaper-policy
Syntax
shaper-policy name
no shaper-policy
Context
config>port>ethernet>network>egress
Description
This command assigns a shaper policy to the specified port.
The shaper policy defines shaper parameters such as shaper group, and PIR and CIR rates. The shaper policy is defined in the config>qos>shaper-policy context. Refer to the 7705 SAR Quality of Service Guide, ‟QoS for Hybrid Ports”, for more information.
The port shaper rate applies to the bulk of access and network traffic. Thus, once the configured egress shaper rate is reached, both the access and network traffic scheduling pauses.
For hybrid ports, there can be a single shaper policy on access egress and a single shaper policy on network egress. Therefore, all the SAP traffic and all the network traffic is each bound to its own shaper group in the shaper policy (access and network shaper policy, respectively). In other words, shaped SAPs and the bulk/aggregate of unshaped SAPs are shaped together as per the shaper policy assigned to the access egress. A similar behavior applies to network traffic, where the shaped interfaces and the bulk/aggregate of unshaped interfaces are shaped together as per the shaper policy assigned to the network egress.
The no form of this command reverts to the default.
Default
‟default”
Parameters
- name
specifies an existing shaper policy name
unshaped-if-cir
Syntax
unshaped-if-cir cir-rate
no unshaped-if-cir
Context
config>port>ethernet>network>egress
Description
This command sets the CIR rate for the aggregate of all the unshaped VLANs (that is, network interfaces) on the port. The default cir-rate is 0 kb/s. When the cir-rate is set to max, the CIR rate adopts the maximum rate of the port. The actual rate of the port is dictated by the physical port speed, which can be overwritten by the egress-rate sub-rate command.
If the cir-rate is higher than the sub-rate, the cir-rate is stored in the configuration database but the sub-rate limit is used.
On Gen-3 hardware, the cir-rate for this command can be configured and is applied but has no effect on the network port, except for network traffic in hybrid mode, where the cir-rate value has an effect.
The no form of the command sets the unshaped-if-cir CIR rate to 0 kb/s.
Default
no unshaped-if-cir
Parameters
- cir-rate
the CIR rate for the aggregate of all the unshaped VLANs on the port

member
Syntax
[no] member port-id
Context
config>port>multilink-bundle
Description
This command binds a channel group to a multilink bundle.
To bind a channel group to a multilink bundle, all the timeslots on the channel group must be allocated.
When you configure a channel group on the network side with ppp-auto encapsulation, the system automatically allocates all timeslots to the channel group. When you configure a channel group on the access side with IPCP encapsulation, the system does not automatically allocate all timeslots to the channel group. In order to use the port or channel group as a member in an multilink bundle, you must manually allocate all the timeslots to the channel group before adding it to the bundle.
The following list specifies the cards, modules, and platforms that support multilink bundles and the number of channel groups on the network and/or access side that can be bound to an MLPPP bundle:
T1/E1 ports on the 7705 SAR-A
Network: 8 Access: 8
T1/E1 ports on the 7705 SAR-M
Network: 16 Access: 8
T1/E1 ports on the 7705 SAR-X

mlppp
Syntax
mlppp
Context
config>port>multilink-bundle
Description
This command enables the context to configure MLPPP bundle attributes.
endpoint-discriminator
Syntax
endpoint-discriminator class {ip-address | global-mac-address | null} [discriminator-id discriminator-id]
no endpoint-discriminator
Context
config>port>multilink-bundle>mlppp
Description
This command configures the endpoint-discriminator class and ID. The port must be shut down to modify the endpoint-discriminator parameters.
If the null option is configured, the 7705 SAR will advertise an endpoint-discriminator class value of NULL in link membership negotiations. If the far-end node rejects the NULL object, the 7705 SAR will remove the object from future requests. The null option should only be used if the far-end node cannot support the ip-address or global-mac-address endpoint-discriminator class options, as these options provide more protection from incorrectly adding a link to an MLPPP bundle.
The no form of this command removes the configured parameters.
Parameters
- class
specifies the link control protocol endpoint-discriminator class field
- discriminator-id
specifies the endpoint-discriminator identifier value within the specified endpoint-discriminator class
magic-number
Syntax
[no] magic-number
Context
config>port>multilink-bundle>mlppp
Description
This command allows loopback detection to be enabled and disabled for MLPPP bundles. The command is disabled by default. When the magic number option is disabled, the magic number option will not be requested when a member is trying to bring up the LCP layer on a member link; if the remote peer requests this option, it will be rejected. When transmitting echo-requests, a magic number of 0 is used. When responding to echo-requests, a magic number of 0 is sent.
If the magic-number option is enabled, the option is sent to the remote peer during protocol negotiation. If this option is rejected by the remote peer, the router will bring the link up but will be unable to detect loopbacks since the router will always send a magic number of 0 in the echo messages upon rejection. If this option is accepted by the remote peer, the router will send echo messages with randomly generated (non-zero) magic numbers. If the 7705 SAR receives a config-req with the same magic number that was sent out, the router will calculate a new magic number to use and send out another config-request. If the router persistently sees the randomly generated magic number in the received config-req, the router will declare a loopback.
The no form of the command disables the loopback detection.
Default
no magic-number
multiclass
Syntax
multiclass count
no multiclass
Context
config>port>multilink-bundle>mlppp
Description
This command enables multi-class MLPPP (MC-MLPPP) as defined by RFC 2686, The Multi-Class Extension to Multi-Link PPP. The 7705 SAR supports MC-MLPPP bundles with 2, 3 or 4 classes. To change the number of classes, all member links must be removed and then the bundle must be shut down.
The packets transmitted on the MC-MLPPP bundle are sent with class values from 0 to one less than the configured class size. For example, a 4-class MLPPP bundle has 4 classes and transmits packets with class numbers 0, 1, 2, and 3. A 4-class bundle transmits packets with class numbers 0, 1 and 2 and a 2-class bundle transmits packets with class numbers 0 and 1. A 0-class MLPPP bundle has the highest priority.
Entries are created and deleted by the system depending on the number of classes being used by a given MLPPP bundle. The no form of the command disables multi-class MLPPP.
Default
no multiclass
Parameters
- count
specifies the number of classes in an MLPPP bundle

framing (DS1)
Syntax
framing {esf | sf | ds1-unframed}
Context
config>port>tdm>ds1
Description
This command specifies the DS1 framing to be used for the port.
The ds1-unframed parameter allows the configuration of an unstructured DS1 channel on the following:
-
16-port T1/E1 ASAP Adapter card
-
32-port T1/E1 ASAP Adapter card
-
2-port OC3/STM1 Channelized Adapter card
-
4-port OC3/STM1 / 1-port OC12/STM4 Adapter card

loopback (DS1)
Syntax
loopback {line | internal | fdl-ansi | fdl-bellcore | payload-ansi}
no loopback
Context
config>port>tdm>ds1
Description
This command puts the specified port or channel in a loopback mode.
A line loopback loops frames received on the corresponding port or channel back toward the transmit (egress) direction before reaching the framer. The bit stream is not reframed. The electrical signal is regenerated by the Tx line interface unit (LIU) and the timing is provided by the Rx LIU. On the 2-port OC3/STM1 Channelized Adapter card, 4-port OC3/STM1 / 1-port OC12/STM4 Adapter card, or 4-port DS3/E3 Adapter card, the traffic is also passed through to the fabric.
An internal loopback loops the frames that are coming in an egress direction from the fabric toward the framer, back to the fabric. This is usually referred to as an equipment loopback. On the 2-port OC3/STM1 Channelized Adapter card, 4-port OC3/STM1 / 1-port OC12/STM4 Adapter card, or 4-port DS3/E3 Adapter card, the frames are also transmitted on the line.
The fdl-ansi loopback command sends a repeating 16-bit ESF data link code word to the remote end requesting that it enter into a network line loopback. The ansi keyword enables the remote line FDL ANSI bit loopback on the T1 line, in accordance with the ANSI T1.403 specification.
The fdl-bellcore loopback command sends a repeating 16-bit ESF data link code word to the remote end requesting that it enter into a network line loopback. The bellcore keyword enables the remote line FDL Bellcore bit loopback on the T1 line, in accordance with the Bellcore TR-TSY-000312 specification.
The payload-ansi loopback command sends a repeating 16-bit ESF data link code word to the remote end requesting that it enter into a network payload loopback. A payload loopback loops frames back toward the transmit (egress) direction after reaching the framer. The bit stream is reframed. The electrical signal is regenerated by the Tx LIU and the timing is provided by the Rx LIU.
The loopback command is not saved to the system configuration.
The no form of this command disables the specified type of loopback.
The fdl-ansi, fdl-bellcore and payload-ansi options can only be configured if DS1 framing is set to ESF.
The 4-port OC3/STM1 / 1-port OC12/STM4 Adapter card cannot initiate fdl-ansi, fdl-bellcore, or payload-ansi loopbacks.
The 4-port OC3/STM1 / 1-port OC12/STM4 Adapter card supports up to 16 line loopbacks and 16 internal loopbacks at a time.
Default
no loopback
Parameters
- line
places the associated port or channel into line loopback mode

Syntax
signal-mode cas
no signal-mode
Context
config>port>tdm>ds1
config>port>tdm>e1
Description
This command enables or disables Channel Associated Signaling (CAS) at the port and circuit levels. When enabled, control signals (such as those for synchronizing and bounding frames) are carried in the same channels as voice and data signals.
If the signal mode for a DS1/E1 port or channel is configured for no signal-mode, all DS0/64 kb/s channels within the DS1 or E1 port will not be enabled for CAS. Individual channel groups within that DS1 or E1 port inherit this state and cannot be changed.
If the signal mode for a DS1/E1 port or channel is configured for signal-mode cas, any new channel groups default to signal-mode cas.
The signal mode must be configured for CAS before creating a Cpipe service that supports T1 or E1 with CAS. Refer to the 7705 SAR Services Guide, ‟Creating a Cpipe Service”, for information on configuring a Cpipe service.

Context
config>port>tdm>ds1>channel-group
config>port>tdm>e1>channel-group
Description
This command puts the specified n ✕ DS0 (64 kb/s) channel group in a loopback mode. For T1 ports, the channel group can have 1 to 24 channels. For E1 ports, the channel group can have 1 to 31 channels.
When a line loopback is enabled on the channel group:
frames received on the channel group on the Rx port are looped back toward the Tx (egress) port before reaching the framer. However, if CAS is enabled on the interface, the Tx signaling bits will continue to be sourced from the far end of the Cpipe (not looped back).
an all-ones pattern is inserted by the framer in the direction of the switch fabric and to the far end of the Cpipe
When an internal loopback (usually referred to as an equipment loopback) is enabled on the channel group:
frames received on the channel group from the switch fabric toward the framer are looped back to the switch fabric and to the far end of the Cpipe. However, if CAS is enabled on the interface, the Rx signaling bits will continue to be sourced from the local access port (not looped back).
traffic received on the channel group will continue to be sent out the Tx (egress) port as if no internal loopback was there
N ✕ DS0 (64 kb/s) channel group loopbacks are only supported on the 16-port T1/E1 ASAP Adapter card and the 32-port T1/E1 ASAP Adapter card.

Context
config>port>tdm>ds1>channel-group
config>port>tdm>e1>channel-group
config>port>tdm>ds3
Description
This command assigns a specific MAC address to an APS port. When the command is issued while the port is operational, IP will issue an ARP, if appropriate, and BPDUs are sent with the new MAC address. Configuring a MAC address using the mac command is only supported for APS channel groups. Physical channel groups do not support the mac command.
The no form of this command removes the configured MAC address. The physical port MAC address will be used instead.
For TDM ports, configuring the MAC address allows the same MAC address to be assigned to ports across two routers in an MC-APS pair for MEF 8.
The mac command is only supported on the 2-port OC3/STM1 Channelized Adapter card and 4-port OC3/STM1 / 1-port OC12/STM4 Adapter card.
Default
no mac
Parameters
- ieee-address
specifies the 48-bit MAC address in the form aa:bb:cc:dd:ee:ff or aa-bb-cc-dd-ee-ff where aa, bb, cc, dd, ee, and ff are hexadecimal numbers. Allowed values are any non-broadcast, non-multicast MAC, and non-IEEE reserved MAC addresses.

Description
This command configures a TDM channel for access or network mode operation.
An access port or channel is used for customer-facing traffic on which services are configured. A Service Access Point (SAP) can only be configured on an access port or channel.
When a port is configured for access mode, the appropriate encap-type must be specified to distinguish the services on the port. Once a TDM channel has been configured for access mode, multiple services can be configured on the TDM channel.
A network port or channel participates in the service provider transport or infrastructure network when a network mode is selected. When the network option is configured, only the ppp-auto encap-type can be configured for the port or channel.
The no form of this command restores the default.

loopback
Syntax
loopback {line | internal | remote}
no loopback
Context
config>port>tdm>ds3
config>port>tdm>e3
Description
This command puts the specified DS3/E3 port into a loopback mode.
A line loopback loops frames received on the corresponding port or channel back towards the transmit (egress) direction before reaching the framer.
An internal loopback loops the frames that are coming in an egress direction from the fabric towards the framer, back to the fabric. This is usually referred to as an equipment loopback.
A remote loopback sends a signal to the remote device to provide a line loopback. To configure a remote loopback, you must enable feac-loop-respond on the far-end DS3/E3 interface, then set the loopback to remote on the near-end DS3/E3 interface. Remote loopback sends a loopback code to the far-end DS3/E3 interface that results in the far end sending out a line loopback.
The loopback command is not saved to the system configuration.
The no form of this command disables loopback on the DS3/E3 port.
Default
no loopback
Parameters
- line
places the associated DS3/E3 port into line loopback mode

LAG Commands
lag
Syntax
[no] lag lag-id
Context
config
Description
This command enables the context in which Link Aggregation Group (LAG) attributes are defined.
A LAG groups two or more Ethernet links (ports) into one logical link. The aggregation of multiple physical links adds redundancy and improves resiliency between two network devices, and allows for load sharing.
On access, network, and hybrid ports, a LAG supports active/standby and active/active operation.
For active/standby operation, the links must be in different subgroups. Links can be on the same platform or adapter card/module or distributed over multiple components. If an active link in a LAG fails, traffic gets redistributed to the standby link.
Load sharing is supported among the active links in a LAG group.
The no form of this command deletes the LAG from the configuration. A LAG can only be deleted while it is administratively shut down. Any dependencies, such as IP interface configurations, must be removed from the LAG before it can be shut down.

dynamic-cost
Syntax
[no] dynamic-cost
Context
config>lag
Description
This command enables OSPF or IS-IS costing of a LAG based on the available aggregated, operational bandwidth.
The path cost is dynamically calculated based on the interface bandwidth. OSPF path cost can be changed through the interface metric or the reference bandwidth.
If dynamic cost is configured, costing is applied based on the total number of links configured and the cost advertised is inversely proportional to the number of links available at the time. This requires that the number of links that are up exceeds the configured LAG threshold value; if the number of links that are up falls below the threshold, the configured threshold action determines whether, and at what cost, this LAG will be advertised (see port-threshold).
For example, a physical link in OSPF has a cost associated with it of 100, and the LAG consists of four physical links. The cost associated with the logical link is 25. If one link fails, the cost is automatically adjusted to 33.
If dynamic cost is not configured and OSPF auto-cost is configured, costing is applied based on the total number of links configured. This cost will remain static provided that the number of links that are up exceeds the configured LAG threshold value; if the number of links that are up falls below the threshold, the configured threshold action determines whether, and at what cost, this LAG will be advertised.
If dynamic cost is configured and OSPF auto-cost is not configured, the cost is determined by the cost configured on the OSPF metric, provided that the number of links that are up exceeds the configured LAG threshold value; if the number of links that are up falls below the threshold, the configured threshold action determines whether this LAG will be advertised.
If neither dynamic cost nor OSPF auto-cost is configured, the cost advertised is determined by the cost configured on the OSPF metric, provided that the number of links that are up exceeds the configured LAG threshold value; if the number of links that are up falls below the threshold, the configured threshold action determines whether this LAG will be advertised.
The no form of this command removes dynamic costing from the LAG.
Default
no dynamic-cost
encap-type
Syntax
encap-type {dot1q | null | qinq}
no encap-type
Context
config>lag
Description
This command configures the encapsulation method used to distinguish customer traffic on a LAG.
The encapsulation type of a LAG must match that of its member links. If the encapsulation type of the LAG is changed, the encapsulation type of all its member links also changes.
The encapsulation type can be changed on the LAG only if there is no interface or service associated with it. If the MTU is set to a non-default value, it will be reset to the default value when the encapsulation type is changed.
The no form of this command reverts to the default encapsulation type.
Default
null — all traffic on the link belongs to a single service or VLAN
Parameters
- dot1q
ingress Ethernet frames carry IEEE 802.1Q tags, each tag signifying a different service
- null
ingress Ethernet frames do not use any tags to indicate a service. As a result, only one service can be configured on a link with null encapsulation.
- qinq
ingress frames carry two tags, where the outer tag is the service provider tag and the inner tag is the customer service tag as defined in 802.1ad
hold-time
Syntax
hold-time down hold-down-time
no hold-time
Context
config>lag
Description
This command specifies the delay between detecting that a LAG is down (all active ports are down) and reporting it to the upper layer protocols.
When a failure in a LAG is detected, it is immediately advertised to the rest of the system, but subsequent failures are not advertised to upper layers until the hold-time down interval has expired.
Specifying a hold time is especially useful in a 1:1 active/standby configuration because the time between detecting that the active link in the LAG is down and the time needed to activate the standby link is very short. The hold time prevents the LAG from being operationally down when switching between the active and standby link.
The no form of this command removes any hold time configured.
Default
no hold-time
Parameters
- hold-down-time
specifies, in tenths of seconds, the hold time before a failure is reported
lacp
Syntax
lacp [mode] [administrative-key admin-key] [system-id system-id] [system-priority priority]
no lacp
Context
config>lag
Description
This command specifies the LACP mode of the LAG. By default, the LACP mode is not set.
Per the IEEE 802.1AX-2008 (IEEE 802.3ad) standard, the Link Aggregation Control Protocol (LACP) provides a standardized means for exchanging information between network devices using LAGs. LACP operates in two modes: passive and active. At least one partner must operate in active mode. For example, if the mode on the CE end is passive, the LACP mode on the 7705 SAR end must be active.
The no form of this command disables LACP.
Default
no lacp
Parameters
- mode
specifies the mode in which LACP operates
- admin-key
specifies an administrative key value to identify the aggregation group on each port configured to use LACP. This value should be configured only in exceptional cases. If it is not specified, a random key is assigned.
- system-id
the 6-byte system identifier in hexadecimal format
- priority
the system priority
lacp-xmit-interval
Syntax

lacp-xmit-stdby
Syntax
[no] lacp-xmit-stdby
Context
config>lag
Description

The no form of this command disables LACP message transmission on the standby link. Disable LACP message transmission on the standby link if the peer does not properly follow the IEEE 802.3ax standard regarding the LACP sync bit.
Default
lacp-xmit-stdby
mac
Syntax
mac ieee-address
no mac
Context
config>lag
Description
This command assigns a specific MAC address to the LAG.
The no form of this command returns the MAC address to the default value.
Default
a default MAC address is assigned by the system
Parameters
- ieee-address
specifies the 48-bit MAC address in the form aa:bb:cc:dd:ee:ff or aa-bb-cc-dd-ee-ff where aa, bb, cc, dd, ee, and ff are hexadecimal numbers. Allowed values are any non-broadcast, non-multicast MAC, and non-IEEE reserved MAC addresses.
mode
Syntax
mode {access | network | hybrid}
no mode
Context
config>lag
Description
This command configures the LAG for access, network, or hybrid mode operation.
An access port is used for customer-facing traffic on which services are configured. A SAP can only be configured on an access port or channel.
A network port participates in the service provider transport or infrastructure network when network mode is selected.
A hybrid port allows a single port to operate in both access and network modes.
The no form of this command restores the default.
Default
network
Parameters
- access
configures the LAG for access mode operation
- network
configures the LAG for network mode operation
- hybrid
configures the LAG for hybrid mode operation
port
Syntax
port port-id [port-id] [priority priority] [sub-group sub-group-id]
no port port-id
Context
config>lag
Description
This command adds ports (links) to a LAG. Multiple ports can be added in one command as long as the maximum is not exceeded. The number of links in a LAG depends on the platform or adapter card/module and the Ethernet port type.
The port configuration of the first port added to the LAG is used to compare to subsequently added ports. All ports must share the same characteristics (MTU, speed, duplex, and so on) as those of the first port; otherwise, they will not be added to the LAG.
The priority parameter sets the priority of the port, which is used by LACP. The lower the value, the higher the priority. The port with the highest priority is the primary port. If two or more ports share the same priority value, the port with the lowest port ID becomes the primary port.
Any configuration changes made to the primary port apply to all member ports of a LAG. For example, port hold-time and MTU settings can be modified directly on the primary port and will be applied to all member ports. Any configuration changes made to non-primary ports are rejected.
The no form of this command removes ports from the LAG.
Default
n/a
Parameters
- port-id
specifies the physical port ID in the slot/mda/port format
- priority
specifies the priority of a port
- sub-group-id
identifies a LAG subgroup. Each port in a LAG must be a member of a subgroup. If no subgroup is specified for an access port, the configuration will fail. If no subgroup is specified for a network port, the port is assigned to subgroup 1.
Subgroups should only be configured on one side of a LAG, not both. If you configure the 7705 SAR with subgroups to handle active/standby operation, the partner system should not be configured with subgroups. Only having one side perform active/standby selection guarantees a consistent selection and fast convergence. Active/standby selection is signaled through LACP from one side of the LAG to the other.
port-threshold
Syntax
port-threshold value [action {dynamic-cost | down}]
no port-threshold
Context
config>lag
Description
This command sets a threshold value and controls the behavior of the LAG if the number of operational links is equal to or below the threshold value.
The no form of this command returns the value to the default.
Default
0 action down
Parameters
- value
the number of operational links at or below which the configured action will be invoked for the LAG. When the number of operational links exceeds the port threshold value, any action taken for being below the threshold value will cease.
- action dynamic-cost
specifies that dynamic costing will be activated if the number of operational links is equal to or below the configured threshold value. The LAG will remain operationally up with a cost relative to the number of operational links. The link will only be regarded as operationally down when all links in the LAG are down.
- action down
specifies that the LAG will be brought operationally down if the number of operational links is equal to or below the configured threshold value. The LAG will only be regarded as up when the number of operational links exceeds the configured threshold value.
selection-criteria
Syntax
selection-criteria [best-port | highest-count | highest-weight] [slave-to-partner] [subgroup-hold-time hold-time]
no selection-criteria
Context
config>lag
Description
This command specifies which criteria is used to select the active subgroup (link) of a LAG. Every time the configuration of a link changes, the selection algorithm is applied.
The no form of this command returns the value to the default.
Default
highest-count
Parameters
- best-port
specifies that all standby ports will have their corresponding transmitters disabled. This parameter is used in static LAG configurations.
- highest-count
specifies the subgroup with the highest number of eligible member links. An eligible member link of a LAG is a member that can potentially become active.
A subgroup can have a maximum of one eligible member link.
- highest-weight
specifies the subgroup with the highest aggregate weight
- slave-to-partner
selects, together with the selection criteria, the active subgroup. An eligible member link of a LAG is a member that can potentially become active. This means it is operationally up (not disabled) for use by the remote side. The slave-to-partner parameter can be used to control whether this latter condition is taken into account. The slave-to-partner parameter does not apply to static LAG configurations.
It is recommended that this parameter be set.
- hold-time
specifies the delay time, in tenths of a second, before switching to a newly selected active subgroup from the existing active subgroup. The timer delay applies only if the existing subgroup remains operationally up. If a value of 0 or no value is specified, the switchover occurs immediately. If a value of infinite is specified, no switchover will occur as long as the subgroup remains up; this setting can be overridden with the tools>perform>force>lag-id command. LACP must be enabled on the LAG.
standby-signaling
Syntax
standby-signaling [lacp | power-off]
no standby-signaling
Context

config>scada>pcm
Description
This command forces a master branch to become active. The command applies only if redundant-mode is set to manual mode.
Default
1
Parameters
- branch-id
the master branch that is forced to become active
redundant-mode
Syntax
redundant-mode redundant-mode
Context
config>scada>mddb
config>scada>pcm
Description
This command configures the redundancy mode for the master inputs of the SCADA bridge.
In manual mode, the branch must be made active manually using the force-active command in order to receive data from the master input. The bridge always broadcasts to both master branches.
In auto mode, both the master branch inputs are received simultaneously. This requires the master input behavior to be similar to an RTU, which transmits data when active and transmits either all 1s (MDDB) or no data (PCM) when inactive.
Default
manual
Parameters
- redundant-mode
specifies the redundancy mode for the master inputs of the SCADA bridge
report-alarm
Syntax
[no] report-alarm [hcmOof] [hcmRai]
Context
config>scada>mddb
Description
This command enables the logging of alarms.
The no form of the command disables the logging of alarms.
Default
no report-alarm
Parameters
- hcmOof
specifies HCM out-of-frame errors
- hcmRai
specifies HCM remote alarm indications
speed
Syntax
speed {600 | 1200 | 2400 | 4800 | 9600 | 19200 | 38400 | 56000}
Context
config>scada>mddb
Description
This command configures the SCADA MDDB speed for RS-232 and X.21 interfaces. SCADA MDDB is supported only at subrate speeds (less than 64 kb/s) on X.21 interfaces.
Default
2400
Parameters
- 600
sets the SCADA MDDB speed at 600 (supported on RS-232 interfaces only)
- 1200
sets the SCADA MDDB speed at 1200
- 2400
sets the SCADA MDDB speed at 2400
- 4800
sets the SCADA MDDB speed at 4800
- 9600
sets the SCADA MDDB speed at 9600
- 19200
sets the SCADA MDDB speed at 19200
- 38400
sets the SCADA MDDB speed at 38400
- 56000
sets the SCADA MDDB speed at 56000
squelch
Syntax
squelch timeout timeout
squelch reset
no squelch
Context
config>scada>mddb
config>scada>pcm
Description
This command enables the squelching function for all branches configured on a bridge. This setting takes priority over the setting at the branch level; that is, if squelch is disabled with this command, it cannot be enabled for individual branches.
The no form of this command disables the squelching function on a bridge.
Default
no squelch
Parameters
- timeout
the interval between when an alarm is raised indicating that a branch has locked up and is continuing to send data to the master, and squelching is triggered
- reset
puts the bridge back into the normal state
squelch-recovery
Syntax
squelch-recovery [mode] [time time]
Context
config>scada>mddb
config>scada>pcm
Description
This command configures squelch recovery attributes. When the squelch-recovery mode is configured as auto, the branch will automatically be put back into the normal state after the configured time. If the branch remains locked up, the branch will automatically be squelched again.
Configuring the squelch-recovery mode as manual disables automatic squelch recovery. To put the bridge back into the normal state, use the squelch reset command.
Default
squelch-recovery manual
Parameters
- mode
specifies the squelch recovery mode
- time
the interval after which the branch will automatically be put back into the normal state
vcb
Syntax
vcb
Context
config>scada
Description
This command enables the context to configure voice conference bridge parameters for a SCADA bridge.
idle-code
Syntax
idle-code abcd-code
no idle-code
Context
config>scada>vcb
Description
This command defines the ABCD signaling code to be transmitted when the E&M interface is configured to transmit idle fault signaling (see fault-signaling).
The no form of the command reverts to the default value.
This command is supported only when VCB is operating in vcb-branch-initiate mode.
Default
0 (for Mu-Law companding)
13 (for A-Law companding)
Parameters
- abcd-code
the 4-bit ABCD value to be transmitted
seized-code
Syntax
seized-code abcd-code
no seized-code
Context
config>scada>vcb
Description
This command defines the ABCD signaling code to be transmitted when the E&M interface is configured to transmit seized fault signaling (see fault-signaling).
The no form of the command reverts to the default value.
This command is supported only when VCB is operating in vcb-branch-initiate mode.
Default
0 (for Mu-Law companding)
13 (for A-Law companding)
Parameters
- abcd-code
the 4-bit ABCD value to be transmitted
