[Tree] (config>port>ethernet>dampening half-life)

Full Context

configure port ethernet dampening half-life

Description

This command configures the half-life decay time and the maximum period of time for which the port up state can be suppressed.

The half-life and max-time values must be set at the same time; the ratio of max-time/ half-life must be less than or equal to 49 and greater than or equal to 1.

Parameters

half-life

Specifies the required elapsed time, in seconds, before penalties decay to one-half the initial amount.

Values

1 to 2000

Default

5

max-time

Specifies the maximum suppression time, in seconds, which is the time it can take after the physical link comes up before the worst case accumulated penalties have decayed to the reuse threshold. The maximum penalty is derived from the maximum suppression time, half-life, and reuse threshold, using the following equation:

maximum penalty = (reuse threshold) ✕ 2 expo:(max-time/half-life)

Values

1 to 43200

Default

20

Context

[Tree] (config>router>policy-options>damping half-life)

Full Context

configure router policy-options damping half-life

Description

This command configures the half-life parameter for the route damping profile.

The half-life value is the time, expressed in minutes, required for a route to remain stable in order for the Figure of Merit (FoM) value to be reduced by one half; for example, if the half-life value is 6 (minutes) and the route remains stable for 6 minutes, then the new FoM value is 3 (minutes). After another 3 minutes pass and the route remains stable, the new FoM value is 1.5 (minutes).

When the FoM value falls below the config>router>policy-options>damping reuse threshold, the route is once again considered valid and can be reused or included in route advertisements.

The no form of this command removes the half life parameter from the damping profile.

Default

no half-life

Parameters

minutes

Specifies the half-life in minutes expressed as a decimal integer.

Values

1 to 45

Full Context

configure service fpipe spoke-sdp hash-label

configure service pw-template hash-label

configure service ipipe spoke-sdp hash-label

configure service epipe spoke-sdp hash-label

Description

This command enables the use of the hash label on a VLL, VPRN or VPLS service bound to any MPLS type encapsulated SDP, as well as to a VPRN service that is using the auto-bind-tunnel with the resolution-filter set to any MPLS tunnel type. This feature is not supported on a service bound to a GRE SDP or for a VPRN service using the autobind mode with the gre option. This feature is also not supported on multicast packets forwarded using RSVP P2MP LSP or mLDP LSP in both the base router instance and in the multicast VPN (mVPN) instance. It is, however, supported when forwarding multicast packets using an IES/VPRN spoke-interface.

When this feature is enabled, the ingress data path is modified such that the result of the hash on the packet header is communicated to the egress data path for use as the value of the label field of the hash label. The egress data path appends the hash label at the bottom of the stack (BoS) and sets the S-bit to one (1).

To allow applications where the egress LER infers the presence of the hash label implicitly from the value of the label, the Most Significant Bit (MSB) of the result of the hash is set before copying into the Hash Label. This means that the value of the hash label will always be in the range [524,288 - 1,048,575] and will not overlap with the signaled/static LSP and signaled/static service label ranges. This also guarantees that the hash label will not match a value in the reserved label range.

The (unmodified) result of the hash continues to be used for the purpose of ECMP and LAG spraying of packets locally on the ingress LER. Note, however, that for VLL services, the result of the hash is overwritten and the ECMP and LAG spraying will be based on service-id when ingress SAP shared queuing is not enabled. However, the hash label will still reflect the result of the hash such that an LSR can use it to perform fine grained load balancing of VLL pseudowire packets.

Packets generated in CPM and that are forwarded labeled within the context of a service (for example, OAM packets) must also include a Hash Label at the BoS and set the S-bit accordingly.

The TTL of the hash label is set to a value of 0.

The user enables the signaling of the hash-label capability under a VLL spoke-sdp, a VPLS spoke-sdp or mesh SDP, or an IES/VPRN spoke interface by adding the signal-capability option. In this case, the decision whether to insert the hash label on the user and control plane packets by the local PE is solely determined by the outcome of the signaling process and can override the local PE configuration. The following are the procedures:

• The local PE will insert the flow label interface parameters sub-TLV with F=1 in the PW ID FEC element in the label mapping message for that spoke SDP or mesh SDP.

• If the remote PE includes this sub-TLV with F=1 or F=0, then local PE must insert the hash label in the user and control plane packets.

• If remote PE does not include this sub-TLV (for example, it does not support it, or it is supported but the user did not enable the hash-label option or the signal-capability option), then the local PE establishes the PW but must not insert the hash label in the user and control packets over that spoke SDP or mesh SDP. If the remote PE does not support the signal-capability option, then there are a couple of possible outcomes:

  • If the hash-label option was enabled on the local configuration of the spoke SDP or mesh SDP at the remote PE, the PW packets received by the local PE will have the hash label included. These packets must be dropped. The only way to solve this is to disable the signaling capability option on the local node which will result in the insertion of the hash label by both PE nodes.

  • If the hash-label option is not supported or was not enabled on the local configuration of the spoke SDP or mesh SDP at the remote PE, the PW received by the local PE will not have the hash label included.

• The user can enable or disable the signal-capability option in CLI as needed. When doing so, the 7450 ESS or 7750 SR must withdraw the label it sent to its peer and send a new label mapping message with the new value of the F bit in the flow label interface parameters sub-TLV of the PW ID FEC element.

The no form of this command disables the use of the hash label.

Default

no hash-label

Full Context

configure router segment-routing sr-policies static-policy head-end

Description

This command associates a head-end location with a statically-defined segment-routing policy. The head-end identifies the router that is the target to install the policy. This is a mandatory parameter and configuration command for enabling the segment-routing policy; if the head-end parameter value is not configured, the execution of the no shutdown command on the static segment routing policy fails.

To associate a static policy with the local router as head-end, the keyword local must be specified. The static policy is associated with another (non-local) router, if the head-end parameter is set to any IPv4 address. When a non-local, static segment routing policy that originates as a BGP route is imported into BGP, the configured head-end address is converted to an IPv4-address specific route-target extended community that is automatically added to the route.

The no form of this command removes the head-end association.

Default

Description

This command configures the time interval to wait before declaring a neighbor down. The factor parameter derives the Hello interval.

The config>router>ldp>if-params>ipv6>hello and config>router>ldp>targ-session>ipv6>hello commands are not supported on the 7450 ESS.

Hold time is local to the system and sent in the Hello messages to the neighbor. Hold time cannot be less than three times the Hello interval. The hold time can be configured globally (applies to all LDP interfaces) or per interface. The most specific value is used.

When LDP session is being set up, the hold down time is negotiated to the lower of the two peers. Once an operational value is agreed upon, the Hello factor is used to derive the value of the Hello interval.

The no form of the command at the interface-parameters and targeted-session level sets the hello timeout and the hello factor to the default values.

The no form of the command, at the interface level, sets the hello timeout and the hello factor to the value defined under the interface-parameters level.

The no form of this command, at the peer level, sets the hello timeout and the hello factor to the value defined under the targeted-session level.

The session must be flapped for the new settings to operate.

Default

Hello Timeout Factors lists the default values.

Parameters

timeout

Configures the time interval, in seconds, that LDP waits before a neighbor down.

Values

1 to 65535

factor

Specifies the number of keepalive messages that should be sent on an idle LDP session in the Hello timeout interval.

Description

This command enables the IS-IS Hello (IIH) message padding to ensure that IS-IS LSPs can traverse the link. When this option is enabled, IS-IS Hello messages are padded to the maximum LSP MTU value, which can be set with the lsp-mtu-size command. If link MTU is greater than the maximum LSP MTU value, padding to the link MTU is applied.

The no form of this command disables IS-IS Hello message padding at this level. However, the router may still perform Hello padding if it was set at a higher level in the configuration. To ensure that Hello message padding is disabled, set all levels of configuration to no hello-padding.

Default

no hello-padding

Parameters

adaptive

Specifies the adaptive padding option; this option is able to detect MTU asymmetry from one side of the connection but uses more overhead than loose padding.

• point-to-point interface—Hello PDUs are padded until the sender declares an adjacency on the link to be in the state up. If the implementation supports RFC 3373/5303, Three-Way Handshake for IS-IS Point-to-Point Adjacencies, then this is when the three-way state is up. If the implementation uses the ‟classic” algorithm described in ISO 10589, this is when the adjacency state is up. If the neighbor does not support the adjacency state TLV, then padding continues.

• broadcast interface—Padding starts until at least one adjacency is up on the interface.

loose

Specifies the loose padding option; the loose padding may not be able to detect certain conditions such as asymmetrical MTUs between the routing devices.

• point-to-point interface—the Hello packet is padded from the initial detection of a new neighbor until the adjacency transitions to the INIT state

• broadcast interface—padding starts until at least one adjacency (broadcast only has up/down) is up on the interface

none

Specifies that the Hello message padding is not enabled at this level, even if it is configured at one of the parent levels.

strict

Specifies the strict padding option.

• point-to-point interface—padding is done for all adjacency states, and is continuous. Strict padding has the most overhead but detects MTU issues on both sides of a link

• broadcast interface—padding is done for all adjacency states, and is continuous. Strict padding has the most overhead but detects MTU issues on both sides of a link

configure router isis interface hello-padding

configure router isis level hello-padding

configure router isis hello-padding

configure router isis interface level hello-padding

Description

This command enables IS-IS Hello (IIH) message padding to ensure that IS-IS LSPs can traverse the link. When this option is enabled, IS-IS Hello messages are padded to the maximum LSP MTU value, which can be set with the lsp-mtu-size command. If link MTU is greater than the maximum LSP MTU value, padding to the link MTU is applied.

The no form of this command disables IS-IS Hello padding at this level. However, the router may still perform Hello padding if it was set at a higher level in the configuration. To ensure that Hello message padding is disabled, set all levels of configuration to no hello-padding.

Default

no hello-padding

Parameters

none

Specifies that the Hello message padding is not enabled at this level, even if it is configured at one of the parent levels.

adaptive

Specifies the adaptive padding option; this option is able to detect LSP MTU asymmetry from one side of the connection but uses more overhead than loose padding.

1. point-to-point interface—Hello PDUs are padded until the sender declares an adjacency on the link to be in state up. If the implementation supports RFC 3373/5303, ‟Three-Way Handshake for IS-IS Point-to- Point Adjacencies” then this is when the three-way state is Up. If the implementation use the ‟classic” algorithm described in ISO 10589, this is when adjacency state is Up. If the neighbor does not support the adjacency state TLV, then padding continues.

2. broadcast interface—Padding starts until at least one adjacency is up on the interface.

loose

Specifies the loose padding option; the loose padding may not be able to detect certain situations such as asymmetrical LSP MTUs between the routing devices.

1. point-to-point interface—The Hello packet is padded from the initial detection of a new neighbor until the adjacency transitions to the INIT state.

2. broadcast interface—Padding starts until there is at least one adjacency (broadcast only has up/down) is up on the interface.

strict

Specifies the strict padding option; this option is the most overhead-intensive but detects LSP MTU issues on both sides of a link.

1. point-to-point interface—Padding is done for all adjacency states, and is continuous.

2. broadcast interface—Padding is done for all adjacency states, and is continuous.

configure router ldp targeted-session peer hello-reduction

Description

This command enables the suppression of periodic targeted Hello messages between LDP peers once the targeted LDP session is brought up.

The config>router>ldp>targ-session>ipv6>hello-reduction command is not supported on the 7450 ESS.

When this feature is enabled, the target Hello adjacency is brought up by advertising the Hold-Time value the user configured in the ‟ hello timeout” parameter for the targeted session. The LSR node will then start advertising an exponentially increasing Hold-Time value in the Hello message as soon as the targeted LDP session to the peer is up. Each new incremented Hold-Time value is sent in a number of Hello messages equal to the value of the argument factor, which represents the dampening factor, before the next exponential value is advertised. This provides time for the two peers to settle on the new value. When the Hold-Time reaches the maximum value of 0xffff (binary 65535), the two peers will send Hello messages at a frequency of every [(65535-1)/local helloFactor] seconds for the lifetime of the targeted-LDP session (for example, if the local Hello Factor is three (3), then Hello messages will be sent every 21844 seconds.

The LSR node continues to compute the frequency of sending the Hello messages based on the minimum of its local Hold-time value and the one advertised by its peer as in RFC 5036. Thus for the targeted LDP session to suppress the periodic Hello messages, both peers must bring their advertised Hold-Time to the maximum value. If one of the LDP peers does not, the frequency of the Hello messages sent by both peers will continue to be governed by the smaller of the two Hold-Time values.

When the user enables the Hello reduction option on the LSR node while the targeted LDP session to the peer is operationally up, the change will take effect immediately. In other words, the LSR node will start advertising an exponentially increasing Hold-Time value in the Hello message, starting with the current configured Hold-Time value.

When the user disables the Hello reduction option while the targeted LDP session to the peer is operationally up, the change in the Hold-Time from 0xffff (binary 65535) to the user configured value for this peer will take effect immediately. The local LSR will immediately advertise the value of the user configured Hold-Time value and will not wait until the next scheduled time to send a Hello to make sure the peer adjusts its local hold timeout value immediately.

In general, any configuration change to the parameters of the T-LDP Hello adjacency (modifying the Hello adjacency Hello Timeout or factor, enabling/disabling Hello reduction, or modifying Hello reduction factor) will cause the LSR node to trigger immediately an updated Hello message with the updated Hold Time value without waiting for the next scheduled time to send a Hello.

The no form of this command disables the Hello reduction feature.

Default

no hello-reduction

configure service vpls stp hello-time

configure service template vpls-template stp hello-time

Description

This command configures the Spanning Tree Protocol (STP) Hello time for the Virtual Private LAN Service (VPLS) STP instance.

The Hello time parameter defines the default timer value that controls the sending interval between BPDU configuration messages by this bridge, on ports where this bridge assumes the designated role.

The active Hello time for the spanning tree is determined by the root bridge (except when the STP is running in RSTP mode, then the Hello time is always taken from the locally configured parameter).

The configured hello-time can also be used to calculate the forward delay. See auto-edge ( config>service>vpls>sap>stp auto-edge, config>service>template>vpls-sap-template>stp auto-edge, config>service>vpls>spoke-sdp>stp auto-edge).

The no form of this command returns the Hello time to the default value.

Full Context

configure card fp hi-bw-mcast-src

Description

This command designates the forwarding plane as a high-bandwidth IP multicast source, expecting the ingress traffic to include high-bandwidth IP multicast traffic. When configured, the system attempts to allocate a dedicated multicast switch fabric plane (MSFP) to the forwarding plane. If a group is specified, all FPs in the group will share the same MSFP. If the alarm parameter is specified and the system cannot allocate a dedicated MSFP to the new group or FP, the FPs will be brought online and generate an event (SYSTEM: 2052 - tmnxChassisHiBwMulticastAlarm). Similarly, if during normal operation there is a failure or removal of resources, an event will be generated if the system cannot maintain separation of MSFPs for the MDAs.

The no form of this command removes the high-bandwidth IP multicast source designation from the forwarding plane.

Default

no hi-bw-mcast-src

Parameters

alarm

Enables event generation if the MDA is required to share an MSFP with another MDA that is in a different group. MDAs within the same group sharing an MSFP will not cause this alarm.

group-id

Specifies the logical MSFP group for the MDA. MDAs configured with the same group-id will be placed on the same MSFP.

Values

0 to 32 (A value of 0 removes the MDA from the group).

Default

By default, ‟none” is used, and the system will attempt to assign a unique MSFP to the MDA.

default-paths-only

When this parameter is specified the system will only attempt to allocate the two default paths (one high priority and one low priority) to dedicated MSFPs.

configure subscriber-mgmt sla-profile egress qos queue high-prio-only

Description

This command configures the value of the percentage of buffer space for the queue, used exclusively by high priority packets. The specified value overrides the default value for the context.

The priority of a packet can only be set in the SAP ingress QoS policy and is only applicable on the ingress queues for a SAP. The high-prio-only parameter is used to override the default value derived from the network-queue command.

The defined high-prio-only value cannot be greater than the MBS size of the queue. Attempting to change the MBS to a value smaller than the high priority reserve will generate an error and fail execution. Attempting to set the high-prio-only value larger than the current MBS size will also result in an error and fail execution.

The no form of this command returns high-prio-only to the size as configured in the QoS policy.

Parameters

percent

The percent parameter is the percentage reserved for high priority traffic on the queue. If a value of 10KBytes is desired, enter the value 10. A value of 0 specifies that none of the MBS of the queue is reserved for high priority traffic. This does not affect RED slope operation for packets attempting to be queued.

Values

configure qos sap-egress policer high-prio-only

Description

This command is used to configure the percentage of the policer’s PIR leaky bucket's MBS (maximum burst size) that is reserved for high-priority traffic. While the mbs value defines the policer’s high-priority violate threshold, the percentage value defined is applied to the mbs value to derive the bucket’s low-priority violate threshold. See the mbs command details for information about which types of traffic are associated with each violate threshold.

Parameters

percent-of-mbs

The percent-of-mbs parameter is required when specifying high-prio-only and is expressed as a percentage.

Values

0 to 100

Context

[Tree] (config>qos>adv-config-policy>child-control>offered-measurement high-rate-hold-time)

Full Context

configure qos adv-config-policy child-control offered-measurement high-rate-hold-time

Description

This command sets a time period that the current offered rate should be maintained for a child policer or queue when it is seen that the offered rate is decreasing. The offered measurement that triggers the hold time is used when the hold timer expires, unless a higher offered rate is seen in the interim. When a higher rate is observed, the hold timer is canceled and the higher offered rate is used immediately.

A possible reason to define a hold timer for an offered rate is to allow a child queue is to dampen the effects of a child with a fluctuating rate on the virtual scheduler. This works similar to the max-decrement in that the child holds on to bandwidth from the virtual scheduler in case it may be needed in the near future.

This parameter has no effect on an increase to the child’s offered rate. If the rate increase is above the change sensitivity, the new offered rate is immediately used.

When this command is not specified or removed, the virtual scheduler immediately reacts to measured decreases in offered load.

The no form of this command is used to remove any currently configured hold time for all child policers and queues associated with the policy. When the hold time is removed, any current hold timers for child policers are automatically canceled.

Parameters

seconds

The hold time configured must be specified in seconds. A value of 0 is equivalent to no high-rate-hold-time.

Default

0

Values

0 to 60

active-min-only

When this optional parameter is specified, the high-rate-hold-time command will accept the optional active-min-only parameter. Attempting to remove the active-min-only parameter from the add command, or removing the add command itself, will fail while active-min-only is enabled on the high-rate-hold-time command. When specified, the respective rate or percentage is treated as the minimum offered rate for a queue, only when the queue has an actual non-zero offered rate. This is intended to limit the artificial increase in offered rate to queues that are currently active. When a queue’s measured offered rate drops to zero, the system stops enforcing the minimum value.

configure oam-pm session ethernet lmm loss-events hli-event

Description

This command sets the high loss interval (HLI) threshold to be monitored and the associated thresholds using the counter of the specified direction. The aggregate is a function of summing forward and backward. This value is only used as a threshold mechanism and is not part of the stored statistics. If the optional clear clear-threshold parameter is not specified, the traffic crossing alarm is stateless. Stateless means the state is not carried forward to other measurement intervals. Each measurement interval is analyzed independently and regardless of any previous window. Each unique event can only be raised once within measurement interval. If the optional clear clear-threshold parameter is specified, the traffic crossing alarm uses stateful behavior. Stateful means each unique previous event state is carried forward to following measurement intervals. If a threshold crossing event is raised another is raised until a measurement interval completes and the clear threshold has not been exceeded. A clear event is raised under that condition.

The no form of this command removes the event threshold for frame loss ratio. The direction must be included with the no command.

Default

no hli-event forward

no hli-event backward

no hli-event aggregate

Parameters

forward

Specifies the threshold is applied to the forward direction count.

backward

Specifies the threshold is applied to the backward direction count.

aggregate

Specifies the threshold is applied to the aggregate count (sum of forward and backward).

raise-threshold

Specifies the rising threshold that determines when the event is to be generated, when the percentage of loss value is reached.

Values

1 to 864000

clear-threshold

Specifies an optional value used for stateful behavior that allows the operator to configure a percentage of loss value lower than the rising percentage to indicate when the clear event should be generated.

Values

0 to 863999

A value of zero means that the HLI counter must be 0.

Description

This command configures the minimum time period the SDP will remain in the operationally down state in response to SDP keepalive monitoring.

This parameter can be used to prevent the SDP operational state from ‟flapping” by rapidly transitioning between the operationally up and operationally down states based on keepalive messages.

When an SDP keepalive response is received that indicates an error condition or the max-drop-count keepalive messages receive no reply, the sdp-id will immediately be brought operationally down. If a keepalive response is received that indicates the error has cleared, the sdp-id will be eligible to be put into the operationally up state only after the hold-down-time interval has expired.

The no form of this command reverts the hold-down-time seconds value to the default setting.

Default

hold-down-time 10

Parameters

seconds

Specifies time, in seconds, expressed as a decimal integer. The SDP ID will remain in the operationally down state before it is eligible to enter the operationally up state. A value of 0 indicates that no hold-down-time will be enforced for SDP ID.

configure vrrp policy priority-event port-down hold-set

Description

This command specifies the amount of time that must pass before the set state for a VRRP priority control event can transition to the cleared state to dampen flapping events. A flapping event continually transitions between clear and set.

The hold-set command is used to dampen the effect of a flapping event. The hold-set value is loaded into a hold-set timer that prevents a set event from transitioning to the cleared state until it expires.

Each time an event transitions between cleared and set, the timer is loaded and begins a countdown to zero. When the timer reaches zero, the event is allowed to enter the cleared state. Entering the cleared state is dependent on the object controlling the event, conforming to the requirements defined in the event itself. It is possible, on some event types, to have another set action reload the hold-set timer. This extends the amount of time that must expire before entering the cleared state.

Once the hold-set timer expires and the event meets the cleared state requirements or is set to a lower threshold, the current set effect on the virtual router instances in-use priority can be removed. As with lag-port-down events, this may be a decrease in the set effect if the clearing amounts to a lower set threshold.

The hold-set command can be executed at any time. If the hold-set timer value is configured larger than the new seconds setting, the timer is loaded with the new hold-set value.

The no form of the command disables the hold timer so that event transitions are processed immediately.

Default

no hold-set

Parameters

seconds

The number of seconds that the hold-set timer waits after an event enters a set state or enters a higher threshold set state, depending on the event type.

The value of 0 disables the hold-set timer, preventing any delay in processing lower set thresholds or cleared events.

Full Context

configure subscriber-mgmt bgp-peering-policy hold-time

Description

This command configures the BGP hold time, expressed in seconds.

The BGP hold time specifies the maximum time BGP waits between successive messages (either keepalive or update) from its peer, before closing the connection.

Even though the router OS implementation allows setting the keepalive time separately, the configured keepalive timer is overridden by the hold-time value under the following circumstances:

If the specified hold-time is less than the configured keepalive time, then the operational keepalive time is set to a third of the hold-time; the configured keepalive time is not changed.

If the hold-time is set to zero, then the operational value of the keepalive time is set to zero; the configured keepalive time is not changed. This means that the connection with the peer is up permanently and no keepalive packets are sent to the peer.

The no form of this command reverts to the default.

Parameters

seconds

Specifies the hold-time, in seconds, expressed as a decimal integer. A value of 0 indicates the connection to the peer is up permanently.

Description

This command configures efm-oam operational transition dampening timers which reduce the number of efm-oam state transitions reported to upper layers.

Default

no hold-time

Parameters

time-value

Indicates the number of seconds that the efm-oam protocol will wait before going back to the operational state after leaving the operational state. Note that the hold-time does not apply if efm-oam moved from operational to link-fault.

A hold-time value of zero indicates that there should be no delay in transitioning to the operational state. A non-zero value will cause the efm-oam protocol to attempt to negotiate with a peer if possible, but it will remain in the send-local-remote-ok state until the hold time has expired if negotiation is successful.

If efm-oam is administratively shutdown while it was in the operational state and then re-enabled when a non-zero hold time is configured, efm-oam will attempt transition to the operational state immediately.

Context

[Tree] (config>port>ethernet hold-time)

Full Context

configure port ethernet hold-time

Description

This command configures port link dampening timers which reduce the number of link transitions reported to upper layer protocols. The hold-time value dampens interface transitions.

When an interface transitions from an up state to a down state, it is immediately advertised to the rest of the system if the hold-time down interval is zero, but if the hold-time down interval is greater than zero, interface down transitions are not advertised to upper layers until the hold-time down interval has expired. Likewise, an interface is immediately advertised as up to the rest of the system if the hold-time up interval is zero, but if the hold-time up interval is greater than zero, up transitions are not advertised until the hold-time up interval has expired.

For ESM SRRP setup, MCS synchronizes subscriber information between the two chassis. After a chassis recovers from a power reset/down, MCS immediately synchronizes all subscriber information at once. The longer the host list, the longer it will take to synchronize the chassis. In a fully populated chassis, it is recommended to allow at least 45 minutes for MCS synchronization. It is also recommended to hold the port down, facing the subscriber, on the recovering chassis for 45 minutes before it is allowed to forward traffic again.

The no form of this command reverts to the default values.

Default

down 0 seconds — No port link down dampening is enabled; link down transitions are immediately reported to upper layer protocols.

up 0 seconds — No port link up dampening is enabled; link up transitions are immediately reported to upper layer protocols.

Parameters

hold-time-up

The delay, in seconds or centiseconds, after which to notify the upper layers when an interface transitions from a down state to an up state.

Values

0 to 36000 seconds, 0 or 10 to 3600000 centiseconds in 5 centisecond increments

The minimum non-zero hold-time-up interval on 10G or higher ports is 10 centiseconds with a granularity of 5 centiseconds. The granularity on 1G ports is 1 second. Centiseconds are not supported on 1G ports.

hold-time-down

The delay, in seconds or centiseconds, after which to notify the upper layers when an interface transitions from an up state to a down state.

Values

0 to 36000 seconds, 0 or 10 to 3600000 centiseconds in 5 centisecond increments

The minimum non-zero hold-time-down interval on 10G or higher ports is 10 centiseconds with a granularity of 5 centiseconds. The granularity on 1G ports is 1 second. Centiseconds are not supported on 1G ports.

Full Context

configure service vpls mrp mvrp hold-time

Description

This command enables the dampening timer and applies to both types of provisioned SAPs – end-station and UNI. When a value is configured for the timer, it controls the delay between detecting that the last provisioned SAP in VPLS goes down and reporting it to the MVRP module. The CPM will wait for the time specified in the value parameter before reporting it to the MVRP module. If the SAP comes up before the hold-timer expires, the event will not be reported to MVRP module.

The non-zero hold-time does not apply for SAP transition from down to up, This kind of transition is reported immediately to MVRP module without waiting for hold-time expiration. Also this parameter applies only to the provisioned SAPs. It does not apply to the SAPs configured with the vpls-sap-template command. Also when end-station QinQ SAPs are present only the ‟no hold-time” configuration is allowed.

The no form of this command disables tracking of the operational status for the last active SAP in the VPLS. MVRP will stop declaring the VLAN only when the last provisioned customer (UNI) SAP associated locally with the service is deleted. Also MVRP will declare the associated VLAN attribute as soon as the first provisioned SAP is created in the associated VPLS instance, regardless of the operational state of the SAP.

Description

This command configures the BGP hold time, expressed in seconds.

The BGP hold time specifies the maximum time BGP waits between successive messages (either keepalive or update) from its peer, before closing the connection. This configuration parameter can be set at three levels: global level (applies to all peers), group level (applies to all peers in group) or neighbor level (only applies to specified peer). The most specific value is used.

Even though the router OS implementation allows setting the keepalive (config>service>vprn>bgp keepalive, config>service>vprn>bgp>group keepalive, config>service>vprn>bgp>group>neighbor keepalive) time separately, the configured keepalive timer is overridden by the hold-time value under the following circumstances:

• If the specified hold-time is less than the configured keepalive time, then the operational keepalive time is set to a third of the hold-time; the configured keepalive time is not changed.

• If the hold-time is set to zero, then the operational value of the keepalive time is set to zero; the configured keepalive time is not changed. This means that the connection with the peer is up permanently and no keepalive packets are sent to the peer.

The no form of this command used at the global level reverts to the default value.

[Tree] (config>router>gmpls>path hop)

Full Context

configure router gmpls path hop

Description

This command specifies the node ID of the hops that the GMPLS LSP should traverse on its way to the egress UNI-C router.

The GMPLS LSP ingress and egress node IDs can be included as the first and the last hop. This is necessary when inter-operating with the Nokia 1830 PSS.

The no form of this command deletes hop list entries for the path. All of the GMPLS LSPs currently using the path are affected. Additionally, all services actively using these GMPLS LSPs are affected. The path must be shut down first in order to delete the hop from the hop list. The no hop hop-index command will not result in any action except a warning message on the console indicating that the path is administratively up.

Parameters

hop-index

Specifies the order of the hops. The LSP always traverses from the lowest hop index to the highest. The hop index does not need to be sequential.

Values

1 to 1024

node-id

Specified the node ID of the transit GMPLS LSR. This can be an IPv4 address or a 32-bit unsigned integer identifier of the data plane switching node of the adjacent UNI-N.

te-link-id

Specifies the ID of the TE Link.

Values

1 to 4294967295

loose

Specifies that the route taken by the GMPLS LSP from the previous hop to this hop can traverse through other LSRs. Multiple hop entries with the node-id are flagged as errors. Either the loose or strict keyword must be specified.

strict

Specifies that the LSP must take a direct path from the previous hop router to this router. No transit routers between the previous router and this router are allowed. If the IP address specified is the interface address, then the LSP must use that interface. If there are direct parallel links between the previous router and this router, and if the system IP address is specified, then any one of the available interfaces can be used by the LSP. The user must ensure that the previous router and this router have a direct link. Multiple hop entries with the same IP address are flagged as errors. Either the loose or strict keyword must be specified.

Platforms

Context

[Tree] (config>router>mpls>path hop)

Full Context

configure router mpls path hop

Description

This command specifies the hops that the LSP should traverse on its way to the egress router. When specified, the IP address can be the interface IP address, a loopback interface address, or the system IP address. If a loopback interface or the system IP address is specified then the LSP can choose the best available interface.

When an IPv6 hop is specified, the interface IP address must be a global unicast IPv6 address. A link-local address is not allowed and is rejected in the configuration if attempted.

Optionally, the LSP ingress and egress IP address can be included as the first and the last hop. A hop list can include the ingress interface IP address, the system IP address, and the egress IP address of any of the hops being specified.

When the sid-label parameter is specified, this command specifies an MPLS label value for a hop in the path of an SR-TE LSP. The label value implied by the SID is only used when the path is used by an SR-TE LSP.

The no form of this command deletes hop list entries for the path. All the LSPs currently using this path are affected. Additionally, all services actively using these LSPs are affected. The path must be shutdown first in order to delete the hop from the hop list. The no hop hop-index command will not result in any action except a warning message on the console indicating that the path is administratively up.

Parameters

hop-index

Specifies the hop index is used to order the hops specified. The LSP always traverses from the lowest hop index to the highest. The hop index does not need to be sequential.

Values

1 to 1024

ip-address

Specifies a loopback interface, the system or network interface IP address of the transit router. An interface IPv6 address must be a global unicast address.

Values

ipv4-address — a.b.c.d

ipv6-address — x:x:x:x:x:x:x:x (eight 16-bit pieces)

x:x:x:x:x:x:d.d.d.d

x — 0 to FFFF (hexadecimal)

d — 0 to 255 (decimal)

loose

This keyword specifies that the route taken by the LSP from the previous hop to this hop can traverse through other routers. Multiple hop entries with the same IP address are flagged as errors. Either the loose or strict keyword must be specified.

strict

This keyword specifies that the LSP must take a direct path from the previous hop router to this router. No transit routers between the previous router and this router are allowed. If the IP address specified is the interface address, then that is the interface the LSP must use. If there are direct parallel links between the previous router and this router and if system IP address is specified, then any one of the available interfaces can be used by the LSP. The user must ensure that the previous router and this router have a direct link. Multiple hop entries with the same IP address are flagged as errors. Either the loose or strict keyword must be specified.

sid-value

Specifies the SID value. The sid-value can be any valid MPLS/SR label value. It is not restricted by any locally-defined label ranges since these may be different on the remote node or adjacency for which the SID is defined.

Values

32 to 1048575

Context

[Tree] (config>service>pw-routing>path hop)

Full Context

configure service pw-routing path hop

Description

This command configures each hop on an explicit path that can be used by one or more dynamic MS-PWs. It specifies the IP addresses of the hops that the MS-PE should traverse. These IP addresses can correspond to the system IP address of each S-PE, or the IP address on which the T-LDP session to a given S-PE terminates.

The no form of this command deletes hop list entries for the path. All the MS-PWs currently using this path are unaffected. Additionally, all services actively using these MS-PWs are unaffected. The path must be shutdown first in order to delete the hop from the hop list. The ‛ no hop hop-index’ command will not result in any action, except for a warning message on the console indicating that the path is administratively up.

Default

no hop

Parameters

hop-index

Specifies a locally significant numeric identifier for the hop. The hop index is used to order the hops specified. The LSP always traverses from the lowest hop index to the highest. The hop index does not need to be sequential.

Values

1 to 1024

ip-address

Specifies the system IP address or terminating IP address for the T-LDP session to the S-PE corresponding to this hop. For a given IP address on a hop, the system will choose the appropriate SDP to use.

configure router mpls lsp primary-p2mp-instance hop-limit

configure router mpls lsp hop-limit

Description

This command specifies the maximum number of hops that an LSP can traverse, including the ingress and egress routers. An LSP is not set up if the hop limit is exceeded. This value can be changed dynamically for an LSP that is already set up with the following implications.

If the new value is less than the current number of hops of the established LSP, the LSP is brought down. The software then tries to re-establish the LSP within the new hop-limit number. If the new value is equal to or greater than the current number hops of the established LSP, the LSP is not affected.

The config>router>mpls>lsp>primary-p2mp-instance> hop-limit command is not supported on the 7450 ESS.

Description

This optional command overrides the config>router>mpls>lsp lsp-name>hop-limit command. This command specifies the total number of hops that an LSP traverses, including the ingress and egress routers.

This value can be changed dynamically for an LSP that is already set up with the following implications:

If the new value is less than the current hops of the established LSP, the LSP is brought down. MPLS then tries to re-establish the LSP within the new hop-limit number. If the new value is equal or more than the current hops of the established LSP then the LSP will be unaffected.

The no form of this command reverts the values defined under the LSP definition using the config>router>mpls>lsp lsp-name>hop-limit command.

configure subscriber-mgmt radius-accounting-policy host-accounting

Description

This command enables per-host accounting. In host accounting mode, the acct-session-id is generated per host. This acct-session-id is uniformly included in all accounting messages (START/INTERIM-UPDATE/STOP) and it can be included in RADIUS Access-Request message.

Accounting counters are based on the queue counters and as such are aggregated for all host sharing the queues within an sla-profile instance. CoA and LI is supported based on the acct-session-id of the host.

The no form of this command reverts to the default.

Parameters

interim-update

Specifies that no interim-update messages are sent for the related subscriber hosts when the session is deleted. Without this keyword, only START and STOP accounting messages are generated when the host is established or terminated. This is equivalent to a time-based accounting where only the duration of the session is required.

Values

10 to 60 seconds

count

Specifies the number of retry requests.

Values

2 to 29

family

Allows the host connectivity checks to be performed for IPv4 endpoint, IPv6 endpoint or both. With family IPv6 configured, host connectivity checks is performed on the global unicast address (assigned via SLAAC or DHCPv6 IA_NA) and link-local address of a Layer 3 RG or bridged hosts. In case of SLAAC assignment, host connectivity can only be performed if the /128 is known (via downstream ND). DHCPv6 PD assigned prefixes is removed if link-local address is determined to be unreachable via host connectivity check” Reachability checks for GUA and link-local address is done simultaneously.

Parameters

source {vrrp | interface}

Specifies the source to be used for generation of subscriber host connectivity verification packets. The vrrp keyword specifies that the VRRP state should be used to select proper IP and MAC (active uses VRID, back-up uses interface addresses). The interface keyword forces the use of the interface mac and ip addresses.

Note:

There are up to 256 possible subnets on a given interface, therefore, the subscriber host connectivity verification tool always uses an address of the subnet to which the given host is pertaining. For group-interfaces, one of the parent subscriber interface subnets (depending on host's address) is used.

action {remove | alarm}

Defines the action taken on a subscriber host connectivity verification failure for a given host. The remove keyword raises an alarm and removes dhcp-state and releases all allocated resources (queues, table entries, and so on). The alarm keyword raises an alarm indicating that the host is disconnected.
