Full Context

configure router p2mp-sr-tree p2mp-policy p2mp-candidate-path

Description

This command configures a candidate path in the P2MP policy entry for the P2MP SR tree.

A P2MP SR policy can contain multiple candidate paths, which are redundant trees. Each candidate path represents a P2MP SR tree with its own traffic engineering constraints. Each candidate path has its own preference; the candidate path with the highest preference is the active P2MP SR tunnel.

The no form of this command removes the specified candidate path from the P2MP SR policy.

Parameters

candidate-path-name

Specifies the name of the candidate path, up to 32 characters.

Full Context

configure router mpls lsp p2mp-id

Description

This command configures the identifier of an RSVP P2MP LSP. An RSVP P2MP LSP is fully identified by the combination of: <P2MP ID, tunnel ID, extended tunnel ID> part of the P2MP session object, and <tunnel sender address, LSP ID> fields in the p2mp sender_template object.

The p2mp-id is a 32-bit identifier used in the session object that remains constant over the life of the P2MP tunnel. It is unique within the scope of the ingress LER.

The no form restores the default value of this parameter.

This command is not supported on the 7450 ESS.

Context

[Tree] (config>service>vprn>pim>if p2mp-ldp-tree-join)

Full Context

configure service vprn pim interface p2mp-ldp-tree-join

Description

This command configures the option to join P2MP LDP tree towards the multicast source for the VPRN service. If p2mp-ldp-tree-join is enabled, a PIM multicast join received on an interface is processed to join P2MP LDP LSP using the in-band signaled P2MP tree for the same multicast flow. LDP P2MP tree is setup towards the multicast source. Route to source of the multicast node is looked up from the RTM. The next-hop address for the route to source is set as the root of LDP P2MP tree.

The no form of command disables joining P2MP LDP tree for IPv4 or IPv6 or both (if both or none is specified).

Default

no p2mp-ldp-tree-join

Parameters

ipv4

Enables dynamic mLDP in-band signaling for IPv4 PIM joins. IPv4 multicast must be enabled; see ipv4-multicast-disable. For backward compatibility p2mp-ldp-tree-join is equivalent to p2mp-ldp-tree-join ipv4.

ipv6

Enables dynamic mLDP in-band signaling for IPv6 PIM joins. IPv6 multicast must be enabled; see ipv6-multicast-disable.

configure router pim interface p2mp-ldp-tree-join

Description

This command configures the option to join the P2MP LDP tree towards the multicast source. If p2mp-ldp-tree-join is enabled, a PIM multicast join received on an interface is processed to join the P2MP LDP LSP, using the in-band signaled P2MP tree for the same multicast flow. LDP P2MP tree is set up towards the multicast source. The route to the multicast node source is looked up from the RTM. The next-hop address for the route to source is set as the root of LDP P2MP tree.

The no form of this command disables joining the P2MP LDP tree for IPv4 or IPv6 or for both (if both or none is specified).

Default

no p2mp-ldp-tree-join

Parameters

ipv4

Enables dynamic MLDP in-band signaling for IPv4 PIM joins. IPv4 multicast must be enabled. For backward compatibility p2mp-ldp-tree-join is equivalent to p2mp-ldp-tree-join ipv4.

ipv6

Enables dynamic MLDP in-band signaling for IPv6 PIM joins. IPv6 multicast must be enabled.

Context

[Tree] (oam p2mp-lsp-ping)

Full Context

oam p2mp-lsp-ping

Description

This command performs an in-band connectivity test for an RSVP P2MP LSP. The echo request message is sent on the active P2MP instance and is replicated in the data path over all branches of the P2MP LSP instance. By default, all egress LER nodes that are leaves of the P2MP LSP instance replies to the echo request message.

LDP P2MP generic-identifier along with source IP address of the head-end node can be used to uniquely identify LDP P2MP LSP in a 7750 SR or 7950 XRS network. LDP p2mp-identifier is a mandatory parameter to test LSP ping. LDP P2MP identifier specified to configure a tunnel-interface on head-end node must be used as p2mp-identifier to test an LSP.

To reduce the scope of the echo reply messages, explicitly enter a list of addresses for the egress LER nodes that are required to reply. A maximum of five addresses can be specified in a single run of the p2mp-lsp-ping command. An LER node can parse the list of egress LER addresses and, if its address is included, it replies with an echo reply message.

The output of the command without the detail option provides a high-level summary of received error codes and success codes. The output of the command with the detail option shows a line for each replying node, as in the output of the LSP ping for a P2P LSP.

The display is delayed until all responses are received or the timer configured in the timeout parameter expires. No other CLI commands can be entered while waiting for the display. Entering A ^C aborts the ping operation. Note that p2mp-lsp-ping is not supported in a VPLS/B-VPLS PMSI context.

The timestamp format to be sent, and to be expected when received in a PDU, is as configured by the config>test-oam>mpls-time-stamp-format command. If RFC 4379 (obsoleted by RFC 8029) is selected, then the timestamp is in seconds and microseconds since 1900, otherwise it is in seconds and microseconds since 1970.

Parameters

lsp-name

Specifies the name, up to 64 characters, that identifies an P2MP LSP to ping.

instance-name

Specifies the name, up to 32 characters, of the specific instance of the P2MP LSP to send the echo request.

s2l-dest-addr ipv4-address

Specifies up to five egress LER system addresses that are required to reply to the LSP ping echo request message.

label-ttl

Specifies the TTL value for the MPLS label, expressed as a decimal integer.

Values

1 to 255

Default

255

p2mp-identifier

Specifies the identifier for an LDP P2MP LSP to ping (applies to the 7750 SR and 7950 XRS only).

Values

1 to 4294967295

vpn-recursive-fec

Adds a VPN recursive FEC element to the launched packet (useful for pinging a VPN BGP inter-AS Option B leaf). This parameter issues an OAM p2mp-lsp-ping with RFC 6512 VPN recursive opaque FEC type 8.

Refer to the "OAM” subsection of the LDP chapter in the 7450 ESS, 7750 SR, 7950 XRS, and VSR MPLS Guide for more information.

leaf-addr	ipv4-address	a.b.c.d

fc-name

Specifies the fc and profile parameters used to indicate the forwarding class and profile of the MPLS echo request packet.

When an MPLS echo request packet is generated in CPM and is forwarded to the outgoing interface, the packet is queued in the egress network queue corresponding to the specified fc and profile parameter values. The marking of the packet's EXP is dictated by the LSP-EXP mappings on the outgoing interface.

When the MPLS echo request packet is received on the responding node, the fc and profile parameter values are dictated by the LSP-EXP mappings of the incoming interface.

When an MPLS echo reply packet is generated in CPM and is forwarded to the outgoing interface, the packet is queued in an egress network queue. The egress network queue is selected according to the fc and profile parameter values determined by the classification of the echo request packet that is being replied to at the incoming interface. The marking of the packet's EXP is dictated by the LSP-EXP mappings on the outgoing interface. The ToS byte is not modified. p2mp-lsp-ping Request Packet and Behavior summarizes this behavior.

Table 1. p2mp-lsp-ping Request Packet and Behavior

Request Packet	Behavior
CPM (sender node)	Echo request packet: packet {tos=1, fc1, profile1} fc1 and profile1 are as entered by the user in the OAM command or default values tos1 as per mapping of {fc1, profile1} to IP precedence in network egress QoS policy of outgoing interface
Outgoing interface (sender node)	Echo request packet: packet queued as {fc1, profile1} ToS field=tos1 not remarked EXP=exp1, as per mapping of {fc1, profile1} to EXP in network egress QoS policy of outgoing interface
Incoming interface (responder node)	Echo request packet: packet {tos1, exp1} exp1 mapped to {fc2, profile2} as per classification in network QoS policy of incoming interface
CPM (responder node)	Echo reply packet: packet {tos=1, fc2, profile2}
Outgoing interface (responder node)	Echo reply packet: packet queued as {fc2, profile2} ToS filed= tos1 not remarked (reply inband or out-of-band) EXP=exp2, if reply is inband, remarked as per mapping of {fc2, profile2} to EXP in network egress QoS policy of outgoing interface
Incoming interface (sender node)	Echo reply packet: packet {tos1, exp2} exp2 mapped to {fc1, profile1} as per classification in network QoS policy of incoming interface

Values

be, l2, af, l1, h2, ef, h1, nc

Default

be

profile {in | out}

Specifies the profile of the LSP ping echo request message.

Default

out

octets

Specifies the size in octets, expressed as a decimal integer, of the MPLS echo request packet, including the IP header but not the label stack. The request payload is padded with zeros to the specified size. Note that an OAM command is not failed if the user enters a size lower than the minimum required to build the packet for the echo request message. The payload is automatically padded to meet the minimum size.

Values

1 to 9786

Default

1

timeout

Specifies the time, in seconds, that is used to override the default timeout value and is the amount of time that the router waits for an echo reply message from all leaves of the P2MP LSP after sending the message request message. Upon the expiration of the message time out, the requesting router no longer waits for reply messages. Any echo reply message received after the request times out is silently discarded.

Context

[Tree] (oam p2mp-lsp-trace)

Full Context

oam p2mp-lsp-trace

Description

This command discovers and displays the hop-by-hop path for a source-to-leaf (S2L) sub-LSP of an RSVP P2MP LSP.

The LSP trace capability allows the user to trace the path of a single S2L path of a P2MP LSP. Its operation is like p2mp-lsp-ping, but the sender of the echo reply request message includes the downstream mapping TLV to request the downstream branch information from a branch LSR or bud LSR. The branch LSR or bud LSR also includes the downstream mapping TLV to report the information about the downstream branches of the P2MP LSP. An egress LER does not include this TLV in the echo response message.

The parameter probe-count operates in the same way as in LSP Trace on a P2P LSP. It represents the maximum number of probes sent per TTL value before stops waiting for echo reply messages. If a response is received from the traced node before reaching maximum number of probes, then no more probes are sent for the same TTL. The sender of the echo request then increments the TTL and uses the information it received in the downstream mapping TLV to start sending probes to the node downstream of the last node which replied. This continues until the egress LER for the traced S2L path replies.

Like p2mp-lsp-ping, an LSP trace probe reports on all egress LER nodes that eventually receive the echo request message, but only the traced egress LER node replies to the last probe.

Any branch LSR node or bud LSR node in the P2MP LSP tree may receive a copy of the echo request message with the TTL in the outer label expiring at this node. However, only a branch LSR or bud LSR that has a downstream branch over which the traced egress LER is reachable responds.

When a branch LSR or bud LSR responds, it sets the global return code in the echo response message to RC=14 - "See DDMAP TLV for Return Code and Return Sub-Code” and the return code in the DDMAP TLV corresponding to the outgoing interface of the branch used by the traced S2L path to RC=8 - "Label switched at stack-depth <RSC>”. Note that p2mp-lsp-trace is not supported in a VPLS/B-VPLS PMSI context.

The timestamp format to be sent, and to be expected when received in a PDU, is as configured by the config>test-oam>mpls-time-stamp-format command. If RFC 4379 (obsoleted by RFC 8029) is selected, then the timestamp is in seconds and microseconds since 1900, otherwise it is in seconds and microseconds since 1970.

Parameters

lsp-name

Specifies the name that identifies an P2MP LSP, up to 64 characters, to ping.

instance-name

Specifies the name, up to 32 characters, of the specific instance of the P2MP LSP to send the echo request.

ip-address

Specifies the egress LER system address of the S2L sub-LSP path which is being traced.

Values

a.b.c.d

fc-name

Specifies the fc and profile parameters are used to indicate the forwarding class and profile of the MPLS echo request packet.

When an MPLS echo request packet is generated in CPM and is forwarded to the outgoing interface, the packet is queued in the egress network queue corresponding to the specified FC and profile parameter values. The marking of the packet's EXP is dictated by the LSP-EXP mappings on the outgoing interface.

When the MPLS echo request packet is received on the responding node, the fc and profile parameter values are dictated by the LSP-EXP mappings of the incoming interface.

When an MPLS echo reply packet is generated in CPM and is forwarded to the outgoing interface, the packet is queued in an egress network queue. The egress network queue is selected according to the fc and profile parameter values determined by the classification of the echo request packet that is being replied to at the incoming interface. The marking of the packet's EXP is dictated by the LSP-EXP mappings on the outgoing interface. The ToS byte is not modified. p2mp-lsp-trace Request Packet and Behavior summarizes this behavior.

[Tree] (config>router>rsvp p2mp-merge-point-abort-timer)

Full Context

configure router rsvp p2mp-merge-point-abort-timer

Description

This command specifies a configurable timer to abort Merge-Point (MP) node procedures for an S2L of a P2MP LSP instance. When a value higher than zero is configured for this timer, it will enter into effect anytime this node activates Merge-Point procedures for one or more P2MP LSP S2L paths. As soon an ingress interface goes operationally down, the Merge-Point node starts the abort timer. Upon expiry of the timer, MPLS will clean up all P2MP LSP S2L paths which ILM is on the failed interface and which have not already received a Path refresh over the bypass LSP.

The no form of this command disables the timer.

configure router mpls p2mp-resignal-timer

Description

This command configures the re-signal timer for a P2MP LSP instance. MPLS will request CSPF to re-compute the whole set of S2L paths of a given active P2MP instance each time the P2MP re-signal timer expires. The P2MP re-signal timer is configured separately from the P2P LSP parameter. MPLS performs a global MBB and moves each S2L sub-LSP in the instance into its new path using a new P2MP LSP ID if the global MBB is successful, regardless of the cost of the new S2L path.

This command is supported on the 7750 SR, 7950 XRS, and with VPLS only on the 7450 ESS.

The no form of this command disables the timer-based re-signaling of P2MP LSPs on this system.

Full Context

configure router mpls ingress-statistics p2mp-template-lsp

Description

This command configures an ingress statistics context matching on the RSVP session name for a RSVP P2MP LSP at the egress LER.

This command is supported on the 7750 SR, 7950 XRS, and with VPLS only on the 7450 ESS.

When the ingress LER signals the path of the S2L sub-LSP, it includes the name of the LSP and that of the path in the Session Name field of the Session Attribute object in the Path message. The encoding is as follows:

Session Name: <lsp-name::path-name>, where lsp-name component is encoded as follows:

• P2MP LSP through the user configuration for L3 multicast in global routing instance: "LspNameFromConfig”

• P2MP LSP as I-PMSI or S-PMSI in L3 mVPN: templateName-SvcId-mTTmIndex

• P2MP LSP as I-PMSI in VPLS/B-VPLS: templateName-SvcId-mTTmIndex

The ingress statistics CLI configuration allows the user to match either on the exact name of the P2MP LSP as configured at the ingress LER or on a context that matches on the template name and the service-id as configured at the ingress LER.

When the matching is performed on a context, the user must enter the RSVP session name string in the format "templateName-svcId” to include the LSP template name as well as the mVPN VPLS/B-VPLS service ID as configured at the ingress LER. In this case, one or more P2MP LSP instances signaled by the same ingress LER could be associated with the ingress statistics configuration and the user is provided with CLI parameter max-stats to limit the maximum number of stat indices that can be assigned to this context. If the context matches more than this value, the additional request for stat indices from this context will be rejected. A background tasks monitors the ingress statistics templates which have one or more matching LSP instances with unassigned stat index and assigns one to them as they are freed.

Note the following rules when configuring an ingress statistics context based on template matching:

• max-stats, once allocated, can be increased but not decreased unless the entire ingress statistics context matching a template name is deleted.

• In order to delete ingress statistics context matching a template name, a shutdown is required.

• An accounting policy cannot be configured or de-configured until the ingress statistics context matching a template name is shut down.

• After deleting an accounting policy from an ingress statistics context matching a template name, the policy is not removed from the log until a "no shut” is performed on the ingress statistics context.

If there are no stat indices available at the time the session of the P2MP LSP matching a template context is signaled and the session state installed by the egress LER, no stats are allocated to the session.

Furthermore, the assignment of stat indices to the LSP names that match the context will also be not deterministic. The latter is due to the fact that a stat index is assigned and released following the dynamics of the LSP creation or deletion by the ingress LER. For example, a multicast stream crosses the rate threshold and is moved to a newly signaled S-PMSI dedicated to this stream. Later on, the same steam crosses the threshold downwards and is moved back to the shared I-PMSI and the P2MP LSP corresponding to the S-PMSI is deleted by the ingress LER.

The no form deletes the ingress statistics context matching on the RSVP session name.

Parameters

rsvp-session-name SessionNameString

Specifies the name of the RSVP P2MP session in the format of "templateName-svcId”. This field can hold up to 64 characters.

sender sender-address

Specifies a string of 15 characters representing the IP address of the ingress LER for the LSP.

configure router mpls p2p-active-path-fast-retry

Description

This command configures a global parameter to allow the user to apply a shorter retry timer for the first try after an active LSP path went down due to a local failure or the receipt of a ResvTear. This timer is used only in the first try. Subsequent retries will continue to be governed by the existing LSP level retry-timer.

The no form of this command disables the timer.

Default

no p2p-active-path-fast-retry

Parameters

[Tree] (config>router>rsvp p2p-merge-point-abort-timer)

Full Context

configure router rsvp p2p-merge-point-abort-timer

Description

This command configures a timer to abort Merge-Point (MP) node procedures for a P2P LSP path. When a value higher than zero is configured for this timer, it will enter into effect anytime this node activates Merge-Point procedures for one or more P2P LSP paths. As soon an ingress interface goes operationally down, the Merge-Point node starts the abort timer. Upon expiry of the timer, MPLS will clean up all P2P LSP paths which ILM is on the failed interface and which have not already received a Path refresh over the bypass LSP.

The no form of this command disables the timer.

Default

no p2p-merge-point-abort-timer

Parameters

Context

[Tree] (config>router>mpls>ingress-stats p2p-template-lsp)

Full Context

configure router mpls ingress-statistics p2p-template-lsp

Description

This command configures an ingress statistics context matching on the RSVP session name for a RSVP P2P auto-LSP at the egress LER.

When the ingress LER signals the path of a template based one-hop-p2p or mesh-p2p auto-lsp, it includes the name of the LSP and that of the path in the Session Name field of the Session Attribute object in the Path message. The encoding is as follows:

Session Name: lsp-name::path-name, where lsp-name component is encoded as follows:

P2MP LSP through the user configuration for Layer 3 multicast in global routing instance: "LspNameFromConfig”

• P2MP LSP as I-PMSI or S-PMSI in L3 mVPN: templateName-SvcId-mTTmIndex

• P2MP LSP as I-PMSI in VPLS/B-VPLS: templateName-SvcId-mTTmIndex.

The ingress statistics CLI configuration allows the user to match either on the exact name of the P2P auto-LSP or on a context that matches on the template name and the destination of the LSP at the ingress LER.

When the matching is performed on a context, the user must enter the RSVP session name string in the format "templateName-svcId” to include the LSP template name as well as the mVPN VPLS/B-VPLS service ID as configured at the ingress LER. In this case, one or more P2MP LSP instances signaled by the same ingress LER could be associated with the ingress statistics configuration. In this case, the user is provided with CLI parameter max-stats to limit the maximum number of stat indices which can be assigned to this context. If the context matches more than this value, the additional request for stat indices from this context will be rejected.

Note the following rules when configuring an ingress statistics context based on template matching:

• max-stats, once allocated, can be increased but not decreased unless the entire ingress statistics context matching a template name is deleted.

• In order to delete ingress statistics context matching a template name, a shutdown is required.

• An accounting policy cannot be configured or de-configured until the ingress statistics context matching a template name is shut down.

• After deleting an accounting policy from an ingress statistics context matching a template name, the policy is not removed from the log until a no shut is performed on the ingress statistics context.

If there are no stat indices available at the time the session of the P2P LSP matching a template context is signaled and the session state installed by the egress LER, no stats are allocated to the session.

Furthermore, the assignment of stat indices to the LSP names that match the context will also be not deterministic. The latter is due to the fact that a stat index is assigned and released following the dynamics of the LSP creation or deletion by the ingress LER. For example, a multicast stream crosses the rate threshold and is moved to a newly signaled S-PMSI dedicated to this stream. Later on, the same steam crosses the threshold downwards and is moved back to the shared I-PMSI and the P2MP LSP corresponding to the S-PMSI is deleted by the ingress LER.

The no form deletes the ingress statistics context matching on the RSVP session name.

Parameters

rsvp-session-name SessionNameString

Specifies the name of the RSVP P2MP session in the format of "templateName-svcId”. This field can hold up to 64 characters.

Description

This command specifies the jitter buffer size, in milliseconds, and payload size, in bytes.

Default

The default value depends on the CEM SAP endpoint type, and if applicable, the number of timeslots as shown in Packet CEM SAP Endpoint Types.

Parameters

milliseconds

Specifies the jitter buffer size in milliseconds (ms).

Configuring the payload size and jitter buffer to values that result in less than 2 packet buffers or greater than 32 packet buffers is not allowed. Setting the jitter butter value to 0 sets it back to the default value.

Values

1 to 250

payload-size bytes

Specifies the payload size (in bytes) of packets transmitted to the packet service network (PSN) by the CEM SAP. This determines the size of the data that will be transmitted over the service. If the size of the data received is not consistent with the payload size then the packet is considered malformed.

Values

0 | 16 to 2048

Default

The default value depends on the CEM SAP endpoint type, and if applicable, the number of timeslots as shown in CEM SAP Endpoint Types.

Table 4. CEM SAP Endpoint Types

Endpoint Type	Timeslots	Default Payload Size (in bytes)
unstructuredE1	—	256

	N >= 16	N x 8
nxDS0WithCas (E1)	N	N x 16
nxDS0WithCas (T1)	N	N x 24

For all endpoint types except for nxDS0WithCas, the valid payload size range is from the default to 2048 bytes.

For nxDS0WithCas, the payload size divide by the number of timeslots must be an integer factor of the number of frames per trunk multi-frame (for example, 16 for E1 trunk and 24 for T1 trunk).

For 1xDS0, the payload size must be a multiple of 2.

For NxDS0, where N > 1, the payload size must be a multiple of the number of timeslots.

For unstructuredE1 and unstructuredT1, the payload size must be a multiple of 32 bytes.

Configuring the payload size and jitter buffer to values that result in less than 2 packet buffers or greater than 32 packet buffer is not allowed.

Setting the payload size to 0 sets it back to the default value.

configure subscriber-mgmt sla-profile egress qos policer packet-byte-offset

configure subscriber-mgmt sla-profile ingress qos policer packet-byte-offset

Description

This command is used to modify the size of each packet handled by the policer by adding or subtracting a number of bytes. The actual packet size is not modified; only the size used to determine the bucket depth impact is changed. The packet-byte-offset command is meant to be an arbitrary mechanism the can be used to either add downstream frame encapsulation or remove portions of packet headers. Both the policing metering and profiling throughput is affected by the offset as well as the stats associated with the policer.

When child policers are adding to or subtracting from the size of each packet, the parent policer’s min-thresh-separation value should also need to be modified by the same amount.

The policer’s packet-byte-offset defined in the QoS policy may be overridden on an sla-profile or SAP where the policy is applied. Packet byte offset settings are not included in the applied rate when (queue) frame based accounting is configured and the policer is managed by HQoS, however the offsets are applied to the statistics.

The no form of this command removes the per packet size modifications from the policer.

Parameters

add bytes

Specifies the packet byte offset. The add keyword is mutually exclusive to the subtract keyword. Either add or subtract must be specified. When add is defined the corresponding bytes parameter specifies the number of bytes that is added to the size each packet associated with the policer for rate metering, profiling and accounting purposes. From the policer’s perspective, the maximum packet size is increased by the amount being added to the size of each packet.

Values

0 to 31

subtract bytes

Specifies the packet byte offset. The subtract keyword is mutually exclusive to the add keyword. Either add or subtract must be specified. When b is defined the corresponding bytes parameter specifies the number of bytes that is subtracted from the size of each packet associated with the policer for rate metering, profiling and accounting purposes. From the policer’s perspective, the maximum packet size is reduced by the amount being subtracted from the size of each packet.

Note:

The minimum resulting packet size used by the system is 1 byte.

This command, within the SAP ingress and egress policer-overrides contexts, is used to override the sap-ingress and sap-egress QoS policy configured packet-byte-offset parameter for the specified policer-id. Packet byte offset settings are not included in the applied rate when (queue) frame based accounting is configured; however, the offsets are applied to the statistics.

The no packet-byte-offset command is used to restore the policer’s packet-byte-offset setting to the policy defined value.

Default

no packet-byte-offset

Parameters

add-bytes

Specifies the number of bytes that are added to the size each packet associated with the policer for rate metering, profiling and accounting purposes. From the policer’s perspective, the maximum packet size is increased by the amount being added to the size of each packet.

Values

1 to 31

sub-bytes

Specifies the number of bytes that are subtracted from the size of each packet associated with the policer for rate metering, profiling and accounting purposes. From the policer’s perspective, the maximum packet size is reduced by the amount being subtracted from the size of each packet.

Values

1 to 64

Description

This command is used to modify the size of each packet handled by the policer by adding or subtracting a number of bytes. The actual packet size is not modified; only the size used to determine the bucket depth impact is changed. The packet-byte-offset command is meant to be an arbitrary mechanism that can be used to either add downstream frame encapsulation or remove portions of packet headers. Both the policing metering and profiling throughput is affected by the offset as well as the stats associated with the policer.

When child policers are adding to or subtracting from the size of each packet, the parent policer’s min-thresh-separation value should also need to be modified by the same amount.

The policer’s packet-byte-offset defined in the QoS policy may be overridden on an sla-profile or SAP where the policy is applied. Packet byte offset settings are not included in the applied rate when (queue) frame-based accounting is configured and the policer is managed by HQoS; however, the offsets are applied to the statistics.

The no form of this command is used to remove per packet size modifications from the policer.

Parameters

add add-bytes

The add keyword is mutually exclusive to the subtract keyword. Either add or subtract must be specified. When add is defined, the corresponding bytes parameter specifies the number of bytes that is added to the size of each packet associated with the policer for rate metering, profiling, and accounting purposes.

Description

This command modifies the size of each packet handled by the queue by adding or subtracting the specified number of bytes. The actual packet size is not modified, only the size used to determine the ingress scheduling and profiling is changed. The packet-byte-offset command is an arbitrary mechanism that can be used to either add downstream frame encapsulation or remove portions of packet headers. Both the scheduling and profiling throughput is affected by the offset as well as the statistics (accounting) associated with the queue. The packet-byte-offset does not apply to drop statistics, received valid statistics, or the offered managed and unmanaged statistics used by Ingress Multicast Path Management.

The no form of this command removes per-packet size modifications from the queue.

Parameters

add-bytes

Specifies the number of bytes added to the size of each packet associated with the queue for scheduling, profiling, and accounting purposes. From the queue’s perspective, the packet size is increased by the amount specified.

Values

0 to 30, in increments of 2

sub-bytes

Specifies the number of bytes subtracted from the size of each packet associated with the queue for scheduling, profiling, and accounting purposes. From the queue’s perspective, the packet size is reduced by the amount specified. The minimum resulting packet size used by the system is 1 byte.

configure qos sap-egress queue packet-byte-offset

Description

This command is used to modify the size of each packet handled by the queue by adding or subtracting a number of bytes. The actual packet size is not modified; only the size used to determine the bucket depth impact is changed.

The packet-byte-offset command is meant to be an arbitrary mechanism the can be used to either add downstream frame encapsulation or remove portions of packet headers.

When a packet-byte-offset value is applied to a queue instance, it adjusts the immediate packet size. This means that the queue rates, i.e., operational PIR and CIR, and queue bucket updates use the adjusted packet size. In addition, the queue statistics will also reflect the adjusted packet size. Scheduler policy rates, which are data rates, will use the adjusted packet size.

The port scheduler max-rate and the priority level rates and weights, if a Weighted Scheduler Group is used, are always on-the-wire rates and thus use the actual frame size. The same applies for the agg-rate-limit on a SAP, a subscriber, or a multiservice Site (MSS) when the queue is port-parented.

When the user enables frame-based-accounting in a scheduler policy or queue-frame-based-accounting with agg-rate-limit in a port scheduler policy, the queue rate will be capped to a user-configured on-the-wire rate and the packet-byte-offset is not included. However, the offsets are applied to the statistics.

The no form of this command is used to remove per packet size modifications from the queue.

Parameters

add-bytes

The add keyword is mutually exclusive to the subtract keyword. Either parameter must be specified. When add is defined, the corresponding bytes parameter specifies the number of bytes that is added to the size of each packet associated with the queue for scheduling and accounting purposes.

Full Context

configure oam-pm session mpls dm pad-tlv-size

Description

This command allows the operator to add an optional Pad TLV to PDU and increase the frame on the wire by the specified amount. Note that this command only configures the size of the padding added to the PDU, and does not configure the total size of the frame on the wire. Since the bit count for the length is a maximum of 255 (8bits) the maximum pad per pad-tlv is between 0, 2 and 257 (type 1B, Length 1B, Length 255). Only a single pad-tlv can be added.

The no form of this command removes the optional TLV.

Parameters

octets

[Tree] (config>system>bluetooth pairing-button)

Full Context

configure system bluetooth pairing-button

Description

This command is used to allow or block the function of the pairing button. This can be used to block the accidental triggering of a pairing operation while there is already a paired device.

The actual behavior of the Bluetooth pairing is dependent on both this command and the power command.

If normal operation is to use the pairing button on the router and on the external device to initiate the Bluetooth connection, then set:

config>system>bluetooth>power enabled-manual

config>system>bluetooth>pairing-button enable

If normal operation is to only require the pairing to be initiated by the external device, then set:

config>system>bluetooth>power enabled-automatic

config>system>bluetooth>pairing-button disable

If normal operation is to not allow the local operator to connect without permission from the central management location, then set:

config>system>bluetooth>power enabled-manual

config>system>bluetooth>pairing-button disable

Then when a connection is desired, the central management station must change the configuration to one of the two options shown above for the time the local operator is connecting. The central management station can change the setting back to block local access after the operations is complete.

Default

pairing-button disable

Parameters

admin-state

Specifies the administrative state.

Values

enable — pairing button can trigger a pairing operation

disable — pairing button does not trigger a pairing operation

Full Context

configure router isis segment-routing adjacency-set parallel

configure router ospf segment-routing adjacency-set parallel

Description

This command indicates that all members of the adjacency set must terminate on the same neighboring node. The system raises a trap if a user attempts to add an adjacency terminating on a neighboring node that differs from the existing members of the adjacency set. In addition, the system stops advertising the adjacency set in IS-IS or OSPF and locally deprograms it.

By default, parallel adjacency sets are advertised in the IGP. The no-advertise option prevents an adjacency set from being advertised in the IGP. It is only allowed in CLI and SNMP if the parallel command is configured.

The no form of this command indicates that the adjacency set can include adjacencies to different next hop nodes.

configure port ethernet access egress queue-group queue-overrides queue parent

Description

This command, when used in the queue-overrides context for a queue group queue, defines an optional weight and cir-weight for the queue treatment by the parent scheduler that further governs the available bandwidth given the queue aside from the queue PIR setting. When multiple schedulers and/or queues share a child status with the parent scheduler, the weight or level parameters define how this queue contends with the other children for the parent bandwidth.

Parameters

weight

Specifies the relative weight of this queue in comparison to other child schedulers and queues while vying for bandwidth on the parent scheduler-name. Any queues or schedulers defined as weighted receive no parental bandwidth until all strict queues and schedulers on the parent have reached their maximum bandwidth or are idle. In this manner, weighted children are considered to be the lowest priority.

Values

0 to 100

Default

1

cir-weight

Specifies the weight the queue uses at the within-cir port priority level. The weight is specified as an integer value from 0 to 100 with 100 being the highest weight. When the cir-weight parameter is set to a value of 0 (the default value), the queue or scheduler does not receive bandwidth during the port schedulers within-cir pass and the cir-level parameter is ignored. If the cir-weight parameter is 1 or greater, the cir-level parameter comes into play.

configure port ethernet access egress queue-group scheduler-override scheduler parent

configure port ethernet access ingress queue-group scheduler-override scheduler parent

Description

This command can be used to override the scheduler's parent weight and CIR weight. The weights apply to the associated level/cir-level configured in the applied scheduler policy. The scheduler name must exist in the applied scheduler policy.

The override weights are ignored if the scheduler does not have a parent command configured in the scheduler policy - this allows the parent of the scheduler to be removed from the scheduler policy without having to remove all of the queue group overrides. If the parent scheduler does not exist, causing the configured scheduler to be fostered on an egress port scheduler, the override weights will be ignored and the default values used; this avoids having non-default weightings for fostered schedulers.

The no form of this command returns the scheduler's parent weight and cir-weight to the value configured in the applied scheduler policy.

Default

no parent

Parameters

weight

Specifies the relative weight of this scheduler in comparison to other child schedulers and queues at the same strict level defined by the level parameter in the applied scheduler policy. Within the level, all weight values from active children at that level are summed and the ratio of each active child's weight to the total distributes the available bandwidth at that level. A weight is considered to be active when the queue or scheduler the weight pertains to has not reached its maximum rate and still has packets to transmit.

A 0 (zero) weight value signifies that the child scheduler will receive bandwidth only after bandwidth is distributed to all other non-zero weighted children in the strict level.

Values

0 to 100

cir-weight

Specifies the relative weight of this scheduler in comparison to other child schedulers and queues at the same cir-level defined by the cir-level parameter in the applied scheduler policy. Within the strict cir-level, all cir-weight values from active children at that level are summed and the ratio of each active child's cir-weight to the total distributes the available bandwidth at that level. A cir-weight is considered to be active when the policer, queue, or scheduler that the cir-weight pertains to has not reached the CIR and still has packets to transmit.

A 0 (zero) cir-weight value signifies that the child scheduler will receive bandwidth only after bandwidth is distributed to all other non-zero weighted children in the strict cir-level.

Description

This command defines an optional parent scheduler that further governs the available bandwidth given the queue aside from the queue’s PIR setting. When multiple schedulers and/or queues share a child status with the parent scheduler, the weight or level parameters define how this queue contends with the other children for the parent’s bandwidth.

Checks are not performed to see if a scheduler-name exists when the parent command is defined on the queue. Scheduler names are configured in the config>qos>scheduler-policy>tier level context. Multiple schedulers can exist with the scheduler-name and the association pertains to a scheduler that should exist on the egress SAP as the policy is applied and the queue created. When the queue is created on the egress SAP, the existence of the scheduler-name is dependent on a scheduler policy containing the scheduler-name being directly or indirectly applied (through a multi-service customer site) to the egress SAP. If the scheduler-name does not exist, the queue is placed in the orphaned operational state. The queue will accept packets but will not be bandwidth limited by a virtual scheduler or the scheduler hierarchy applied to the SAP. The orphaned state must generate a log entry and a trap message. The SAP which the queue belongs to must also depict an orphan queue status. The orphaned state of the queue is automatically cleared when the scheduler-name becomes available on the egress SAP.

The parent scheduler can be made unavailable due to the removal of a scheduler policy or scheduler. When an existing parent scheduler is removed or inoperative, the queue enters the orphaned state and automatically returns to normal operation when the parent scheduler is available again.

When a parent scheduler is defined without specifying weight or strict parameters, the default bandwidth access method is weight with a value of 1.

The no form of this command removes a child association with a parent scheduler. If a parent association does not currently exist, the command has no effect and returns without an error. Once a parent association has been removed, the former child queue attempts to operate based on its configured rate parameter. Removing the parent association on the queue within the policy takes effect immediately on all queues using the SAP egress QoS policy.

Parameters

weight

These optional keywords are mutually exclusive to the level keyword. Specifies the relative weight of this queue in comparison to other child schedulers, policers, and queues while vying for bandwidth on the parent scheduler-name. Any policers, queues, or schedulers defined as weighted receive no parental bandwidth until all policers, queues, and schedulers with a higher (numerically larger) priority on the parent have reached their maximum bandwidth or are idle.

All weight values from all weighted active policers, queues, and schedulers with a common parent scheduler are added together. Then, each individual active weight is divided by the total, deriving the percentage of remaining bandwidth provided to the policer, queue, or scheduler. A weight is considered to be active when the pertaining policer, queue, or scheduler has not reached its maximum rate and still has packets to transmit. All child policers, queues, and schedulers with a weight of 0 are considered to have the lowest priority level and are not serviced until all non-zero weighted policers, queues, and schedulers at that level are operating at the maximum bandwidth or are idle.

Values

0 to 100

Default

1

cir-weight

Specifies the weight the queue or scheduler will use at the within-cir port priority level (defined by the cir-level parameter). The weight is specified as an integer value from 0 to 100 with 100 being the highest weight. When the cir-weight parameter is set to a value of 0 (the default value), the policer, queue, or scheduler does not receive bandwidth during the port schedulers within-cir pass and the cir-level parameter is ignored. If the cir-weight parameter is 1 or greater, the cir-level parameter comes into play.

Description

This command can be used to override the scheduler’s parent weight and cir-weight information. The weights apply to the associated level/cir-level configured in the applied scheduler policy. The scheduler name must exist in the scheduler policy applied to the ingress or egress of the SAP or multi-service site.

The override weights are ignored if the scheduler does not have a parent command configured in the scheduler policy – this allows the parent of the scheduler to be removed from the scheduler policy without having to remove all of the SAP/MSS overrides. If the parent scheduler does not exist causing the configured scheduler to be fostered on an egress port scheduler, the override weights will be ignored and the default values used; this avoids having non-default weightings for fostered schedulers.

The no form of this command returns the scheduler’s parent weight and cir-weight to the value configured in the applied scheduler policy.

Default

no parent

Parameters

weight

Specifies the relative weight of this scheduler in comparison to other child schedulers, policers, and queues at the same strict level defined by the level parameter in the applied scheduler policy. Within the level, all weight values from active children at that level are summed and the ratio of each active child’s weight to the total is used to distribute the available bandwidth at that level. A weight is considered to be active when the policer, queue, or scheduler the weight pertains to has not reached its maximum rate and still has packets to transmit.

A 0 (zero) weight value signifies that the child scheduler will receive bandwidth only after bandwidth is distributed to all other non-zero weighted children in the strict level.

Values

0 to 100

cir-weight

Specifies the relative weight of this scheduler in comparison to other child schedulers, policers, and queues at the same cir-level defined by the cir-level parameter in the applied scheduler policy. Within the strict cir-level, all cir-weight values from active children at that level are summed and the ratio of each active child’s cir-weight to the total is used to distribute the available bandwidth at that level. A cir-weight is considered to be active when the policer, queue, or scheduler that the cir-weight pertains to has not reached the CIR and still has packets to transmit.

A 0 (zero) cir-weight value signifies that the child scheduler will receive bandwidth only after bandwidth is distributed to all other non-zero weighted children in the strict cir-level.

Multiple schedulers can exist with the scheduler-name and the association pertains to a scheduler that should exist on the egress SAP as the policy is applied and the queue created. When the queue is created on the egress SAP, the existence of the scheduler-name is dependent on a scheduler policy containing the scheduler-name being directly or indirectly applied (through a multi-service customer site) to the egress SAP. If the scheduler-name does not exist, the queue is placed in the orphaned operational state. The queue will accept packets but will not be bandwidth limited by a virtual scheduler or the scheduler hierarchy applied to the SAP. The orphaned state must generate a log entry and a trap message. The SAP which the queue belongs to must also depict an orphan queue status. The orphaned state of the queue is automatically cleared when the scheduler-name becomes available on the egress SAP.

The parent scheduler can be made unavailable due to the removal of a scheduler policy or scheduler. When an existing parent scheduler is removed or inoperative, the queue enters the orphaned state mentioned above and automatically return to normal operation when the parent scheduler is available again.

When a parent scheduler is defined without specifying weight or strict parameters, the default bandwidth access method is weight with a value of 1.

The no form of this command removes a child association with a parent scheduler. If a parent association does not currently exist, the command has no effect and returns without an error. Once a parent association has been removed, the former child queue attempts to operate based on its configured rate parameter. Removing the parent association on the queue within the policy takes effect immediately on all queues using the SAP egress QoS policy.

Parameters

weight

These optional keywords are mutually exclusive to the level keyword. The weight defines the relative weight of this queue in comparison to other child schedulers, policers, and queues while vying for bandwidth on the parent scheduler-name. Any policers, queues, or schedulers defined as weighted receive no parental bandwidth until all policers, queues, and schedulers with a higher (numerically larger) priority on the parent have reached their maximum bandwidth or are idle.

All weight values from all weighted active policers, queues, and schedulers with a common parent scheduler are added together. Then, each individual active weight is divided by the total, deriving the percentage of remaining bandwidth provided to the policer, queue, or scheduler. A weight is considered to be active when the pertaining policer, queue, or scheduler has not reached its maximum rate and still has packets to transmit. All child policers, queues, and schedulers with a weight of 0 are considered to have the lowest priority level and are not serviced until all non-zero weighted policers, queues, and schedulers at that level are operating at the maximum bandwidth or are idle.

Values

0 to 100

Default

1

cir-weight

Specifies the weight the queue or scheduler will use at the within-cir port priority level (defined by the cir-level parameter). The weight is specified as an integer value from 0 to 100 with 100 being the highest weight. When the cir-weight parameter is set to a value of 0 (the default value), the policer, queue, or scheduler does not receive bandwidth during the port schedulers within-cir pass and the cir-level parameter is ignored. If the cir-weight parameter is 1 or greater, the cir-level parameter comes into play.

Description

This command can be used to override the scheduler’s parent weight and cir-weight information. The weights apply to the associated level/cir-level configured in the applied scheduler policy. The scheduler name must exist in the scheduler policy applied to the ingress or egress of the SAP or multi-service site.

The override weights are ignored if the scheduler does not have a parent command configured in the scheduler policy – this allows the parent of the scheduler to be removed from the scheduler policy without having to remove all of the SAP/MSS overrides. If the parent scheduler does not exist causing the configured scheduler to be fostered on an egress port scheduler, the override weights will be ignored and the default values used; this avoids having non-default weightings for fostered schedulers.

The no form of this command returns the scheduler’s parent weight and cir-weight to the value configured in the applied scheduler policy.

Default

no parent

Parameters

weight

Specifies the relative weight of this scheduler in comparison to other child schedulers and queues at the same strict level defined by the level parameter in the applied scheduler policy. Within the level, all weight values from active children at that level are summed and the ratio of each active child’s weight to the total is used to distribute the available bandwidth at that level. A weight is considered to be active when the policer, queue, or scheduler the weight pertains to has not reached its maximum rate and still has packets to transmit.

A 0 (zero) weight value signifies that the child scheduler will receive bandwidth only after bandwidth is distributed to all other non-zero weighted children in the strict level.

Values

0 to 100

cir-weight

Specifies the relative weight of this scheduler in comparison to other child schedulers and queues at the same cir-level defined by the cir-level parameter in the applied scheduler policy. Within the strict cir-level, all cir-weight values from active children at that level are summed and the ratio of each active child’s cir-weight to the total is used to distribute the available bandwidth at that level. A cir-weight is considered to be active when the policer, queue, or scheduler that the cir-weight pertains to has not reached the CIR and still has packets to transmit.

A 0 (zero) cir-weight value signifies that the child scheduler will receive bandwidth only after bandwidth is distributed to all other non-zero weighted children in the strict cir-level.

configure qos policer-control-policy tier arbiter parent

Description

This command is used to define from where the tiered arbiter receives bandwidth. Both tier 1 and tier 2 arbiters default to parenting to the root arbiter. Tier 2 arbiters may be modified to parent to a tier 1 arbiter. The tier 1 arbiter parent cannot be changed.

The no form of this command is used to return the tiered arbiter to the default parenting behavior.

Default

parent root level 1 weight 1

Parameters

root

In tier 1, arbiter-name is not allowed and only root is accepted. When root is specified, the arbiter will receive all bandwidth directly from the root arbiter. This is the default parent for tiered arbiters.

arbiter-name

In tier 1, arbiter-name is not allowed and only root is accepted. The specified arbiter-name must exist within the policer-control-policy at tier 1 or the parent command will fail. When a tiered arbiter is acting as a parent for another tiered arbiter, the parent arbiter cannot be removed from the policy. The child arbiter will receive all bandwidth directly from its parent arbiter (that receives bandwidth from the root arbiter).

priority-level

Each child arbiter attaches to its parent on one of the parent’s eight strict levels. Level 1 is the lowest and 8 is the highest. The level attribute is used to define which level the child arbiter uses on its parent. The parent distributes its available bandwidth based on strict priority starting with priority level 8 and proceeding towards level 1.

Values

1 to 8

Default

1

weight-within-level

The weight attribute is used to define how multiple children at the same parent strict level compete when insufficient bandwidth exists on the parent for that level. Each child's weight is divided by the sum of the active children's weights and the result is multiplied by the available bandwidth. If a child cannot receive its entire weighted fair share of bandwidth due to a defined child rate limit, the remainder of its bandwidth is distributed between the other children based on their weights.

Values

1 to 100

configure qos sap-ingress policer parent

configure qos sap-egress policer parent

configure qos sap-ingress dynamic-policer parent

Description

This command is used to create a child-to-parent mapping between each instance of the policer and either the root arbiter or a specific tiered arbiter on the object where the policy is applied. Defining a parent association for the policer causes the policer to compete for the parent policer’s available bandwidth with other child policers mapped to the policer control hierarchy.

Policer control hierarchies may be created on SAPs or on a subscriber or multiservice site context. To create a policer control hierarchy on an ingress or egress SAP context, a policer-control-policy must be applied to the SAP. When applied, the system will create a parent policer that is bandwidth limited by the policy’s max-rate value under the root arbiter. The root arbiter in the policy also provides the information used to determine the various priority-level discard-unfair and discard-all thresholds. Besides the root arbiter, the policy may also contain user-defined tiered arbiters that provide arbitrary bandwidth control for subsets of child policers that are either directly or indirectly parented by the arbiter.

When the QoS policy containing the policer with a parent mapping to an arbiter name exists on the SAP, the system will scan the available arbiters on the SAP. If an arbiter exists with the appropriate name, the policer to arbiter association is created. If the specified arbiter does not exist either because a policer-control-policy is not currently applied to the SAP or the arbiter name does not exist within the applied policy, the policer is placed in an orphan state. Orphan policers operate as if they are not parented and are not subject to any bandwidth constraints other than their own PIR. When a policer enters the orphan state, it is flagged as operationally degraded due to the fact that it is not operating as intended and a trap is generated. Whenever a policer-control-policy is added to the SAP or the existing policy is modified, the SAP's policer's parenting configurations must be reevaluated. If an orphan policer becomes parented, the degraded flag is cleared, and a resulting trap is generated.

For subscribers, the policer control hierarchy is created through the policer-control-policy applied to the sub-profile used by the subscriber. A unique policer control hierarchy is created for each subscriber associated with the sub-profile. The QoS policy containing the policer with the parenting command comes into play through the subscriber sla-profile, which references the QoS policy. The combining of the sub-profile and the sla-profile at the subscriber level provides the system with the proper information to create the policer control hierarchy instance for the subscriber. This functionality is available only for the 7450 ESS and 7750 SR.

Executing the parent command will fail if:

• The policer’s stat-mode in the QoS policy is set to no-stats

• A stat-mode no-stats override exists on an instance of the policer on a SAP or subscriber or multiservice site context

A policer with a parent command applied cannot be configured with stat-mode no-stats in either the QoS policy or as an override on an instance of the policer.

When a policer is successfully parented to an arbiter, the parent commands level and weight parameters are used to determine at what priority level and at which weight in the priority level that the child policer competes with other children (policers or other arbiters) for bandwidth.

The no form of this command is used to remove the parent association from all instances of the policer.

Parameters

{root | arbiter-name}

When the parent command is executed, either the keyword root or an arbiter-name must be specified.

root

Specifies that the policer is intended to become a child to the root arbiter where an instance of the policer is created. If the root arbiter does not exist, the policer will be placed in the orphan state.

Default

root

arbiter-name

Specifies that the policer is intended to become a child to one of the tiered arbiters with the given arbiter-name where an instance of the policer is created. If the specified arbiter-name does not exist, the policer will be placed in the orphan state.

weight weight-within-level

The weight weight-within-level keyword and parameter are optional when executing the parent command. When weight is not specified, a default level of 1 is used in the parent arbiter’s priority level. When weight is specified, the weight-within-level parameter must be specified as an integer value from 1 through 100.

Description

This command defines an optional parent scheduler that further governs the available bandwidth given the queue aside from the queue’s PIR setting. When multiple schedulers, policers (at egress only), and/or queues share a child status with the parent scheduler, the weight or level parameters define how this queue contends with the other children for the parent’s bandwidth.

Checks are not performed to see if a scheduler-name exists when the parent command is defined on the queue. Scheduler names are configured in the config>qos>scheduler-policy>tier level context. Multiple schedulers can exist with the scheduler-name and the association pertains to a scheduler that should exist on the egress SAP as the policy is applied and the queue created. When the queue is created on the egress SAP, the existence of the scheduler-name is dependent on a scheduler policy containing the scheduler-name being directly or indirectly applied (through a multiservice customer site) to the egress SAP. If the scheduler-name does not exist, the queue is placed in the orphaned operational state. The queue will accept packets but will not be bandwidth limited by a virtual scheduler or the scheduler hierarchy applied to the SAP. The SAP that the queue belongs to also depicts an orphan queue status. The orphaned state of the queue is automatically cleared when the scheduler-name becomes available on the egress SAP.

The parent scheduler can be made unavailable due to the removal of a scheduler policy or scheduler. When an existing parent scheduler is removed or inoperative, the queue enters the orphaned state and automatically returns to normal operation when the parent scheduler is available again.

When a parent scheduler is defined without specifying the weight parameter, the default is a weight of 1.

The no form of this command removes a child association with a parent scheduler. If a parent association does not currently exist, the command has no effect and returns without an error. When a parent association has been removed, the former child queue attempts to operate based on its configured rate parameter. Removing the parent association on the queue within the policy takes effect immediately on all queues using the SAP egress QoS policy.

Parameters

scheduler-name

The defined scheduler-name conforms to the same input criteria as the schedulers defined within a scheduler policy. Scheduler names are configured in the config>qos>scheduler-policy>tier level context. There are no checks performed at the time of definition to ensure that the scheduler-name exists within an existing scheduler policy. For the queue to use the defined scheduler-name, the scheduler exists on each egress SAP that the queue is eventually created on. For the duration where scheduler-name does not exist on the egress SAP, the queue operates in an orphaned state.

Values

Any string up to 32 characters, composed of printable, 7-bit ASCII characters. If the string contains special characters (#, $, spaces, etc.), the entire string must be enclosed within double quotes.

weight

Specifies the relative weight of this queue in comparison to other child schedulers, policers, and queues, while vying for bandwidth on the parent scheduler-name. Any queues, policers, or schedulers defined as weighted receive no parental bandwidth until all policers, queues, and schedulers with a higher (numerically larger) priority on the parent have reached their maximum bandwidth or are idle.

All weight values from all weighted active queues, policers, and schedulers with a common parent scheduler are added together. Then, each individual active weight is divided by the total, deriving the percentage of remaining bandwidth provided to the queue, policer, or scheduler. A weight is considered to be active when the pertaining queue, policer, or scheduler has not reached its maximum rate and still has packets to transmit. All child queues, policers, and schedulers with a weight of 0 are considered to have the lowest priority level and are not serviced until all non-zero weighted queues, policers, and schedulers at that level are operating at the maximum bandwidth or are idle.

Values

0 to 100

Default

1

level

The optional level parameter defines the level of hierarchy when compared to other schedulers and queues competing for bandwidth on the parent scheduler-name. Queues or schedulers will not receive parental bandwidth until all queues, policers, and schedulers with a higher (numerically larger) priority on the parent have reached their maximum bandwidth or are idle.

Children of the parent scheduler with a lower strict priority will not receive bandwidth until all children with a higher strict priority have either reached their maximum bandwidth or are idle. Children with the same strict level are serviced in relation to their relative weights.

Values

1 to 8

Default

1

cir-weight

Specifies the weight that the queue or scheduler uses at the within-CIR port priority level (defined by the cir-level parameter). The weight is specified as an integer value from 0 to 100 with 100 being the highest weight. When the cir-weight parameter is set to a value of 0 (the default value), the queue or scheduler does not receive bandwidth during the port schedulers within-CIR pass and the cir-level parameter is ignored. If the cir-weight parameter is 1 or greater, the cir-level parameter comes into play.

Values

0 to 100

Default

1

cir-level

Specifies the port priority that the queue or scheduler will use to receive bandwidth for its within-CIR offered-load. If the cir-weight parameter is set to a value of 0 (the default value), the queue or scheduler does not receive bandwidth during the port schedulers within-CIR pass and the cir-level parameter is ignored. If the cir-weight parameter is 1 or greater, the cir-level parameter comes into play.

Description

This command is used to create a child-to-parent mapping between each instance of the policer and either the root arbiter or a specific tiered arbiter on the object where the policy is applied. Defining a parent association for the policer causes the policer to compete for the parent policer’s available bandwidth with other child policers mapped to the policer control hierarchy.

Policer control hierarchies may be created on SAPs or on a subscriber or multiservice site context. To create a policer control hierarchy on an ingress or egress SAP context, a policer-control-policy must be applied to the SAP. When applied, the system will create a parent policer that is bandwidth limited by the policy’s max-rate value under the root arbiter.

Besides the root arbiter, the policy may also contain user-defined tiered arbiters that provide arbitrary bandwidth control for subsets of child policers that are either directly or indirectly parented by the arbiter.

When the QoS policy containing the policer with a parent mapping to an arbiter name exists on the SAP, the system will scan the available arbiters on the SAP. If an arbiter exists with the appropriate name, the policer to arbiter association is created. If the specified arbiter does not exist either because a policer-control-policy is not currently applied to the SAP or the arbiter name does not exist within the applied policy, the policer is placed in an orphan state. Orphan policers operate as if they are not parented and are not subject to any bandwidth constraints other than their own PIR. When a policer enters the orphan state, it is flagged as operationally degraded due to the fact that it is not operating as intended and a trap is generated. Whenever a policer-control-policy is added to the SAP or the existing policy is modified, the SAP's policer's parenting configurations must be reevaluated. If an orphan policer becomes parented, the degraded flag is cleared and a resulting trap is generated.

For subscribers, the policer control hierarchy is created through the policer-control-policy applied to the sub-profile used by the subscriber. A unique policer control hierarchy is created for each subscriber associated with the sub-profile. The QoS policy containing the policer with the parenting command comes into play through the subscriber sla-profile that references the QoS policy. The combining of the sub-profile and the sla-profile at the subscriber level provides the system with the proper information to create the policer control hierarchy instance for the subscriber. This functionality is available only for the 7450 ESS and 7750 SR.

Executing the parent command will fail if:

• The policer’s stat-mode in the QoS policy is set to no-stats

• A stat-mode no-stats override exists on an instance of the policer on a SAP or subscriber or multiservice site context

A policer with a parent command applied cannot be configured with stat-mode no-stats in either the QoS policy or as an override on an instance of the policer.

When a policer is successfully parented to an arbiter, the parent commands level and weight parameters are used to determine at what priority level and at which weight in the priority level that the child policer competes with other children (policers or other arbiters) for bandwidth.

The no form of this command is used to remove the parent association from all instances of the policer.

Parameters

{root | arbiter-name}

When the parent command is executed, either the keyword root or an arbiter-name must be specified.

Default

root

root

The root keyword specifies that the policer is intended to become a child to the root arbiter where an instance of the policer is created. If the root arbiter does not exist, the policer will be placed in the orphan state.

arbiter-name

The arbiter-name parameter specifies that the policer is intended to become a child to one of the tiered arbiters with the given arbiter-name where an instance of the policer is created. If the specified arbiter-name does not exist, the policer will be placed in the orphan state.

weight weight-within-level

The weight weight-within-level keyword and parameter are optional when executing the parent command. When weight is not specified, a default level of 1 is used in the parent arbiters priority level. When weight is specified, the weight-within-level parameter must be specified as an integer value from 1 through 100.

When the queue is created on the egress SAP, the existence of the scheduler-name is dependent on a scheduler policy containing the scheduler-name being directly or indirectly applied (through a multiservice customer site) to the egress SAP. If the scheduler-name does not exist, the queue is placed in the orphaned operational state. The queue will accept packets but will not be bandwidth limited by a virtual scheduler or the scheduler hierarchy applied to the SAP. The SAP that the queue belongs to must also depict an orphan queue status. The orphaned state of the queue is automatically cleared when the scheduler-name becomes available on the egress SAP.

The parent scheduler can be made unavailable due to the removal of a scheduler policy or scheduler. When an existing parent scheduler is removed or inoperative, the queue enters the orphaned state and automatically returns to normal operation when the parent scheduler is available again.

When a parent scheduler is defined without specifying weight or strict parameters, the default bandwidth access method is weight with a value of 1.

The no form of this command removes a child association with a parent scheduler. If a parent association does not currently exist, the command has no effect and returns without an error. When a parent association has been removed, the former child queue attempts to operate based on its configured rate parameter. Removing the parent association on the queue within the policy takes effect immediately on all queues using the SAP egress QoS policy.

Parameters

scheduler-name

The defined scheduler-name conforms to the same input criteria as the schedulers defined within a scheduler policy. Scheduler names are configured in the config>qos>scheduler-policy>tier level context. There are no checks performed at the time of definition to ensure that the scheduler-name exists within an existing scheduler policy. For the queue to use the defined scheduler-name, the scheduler exists on each egress SAP the queue is eventually created on. For the duration where scheduler-name does not exist on the egress SAP, the queue operates in an orphaned state.

Values

Any string up to 32 characters, composed of printable, 7-bit ASCII characters. If the string contains special characters (#, $, spaces, etc.), the entire string must be enclosed within double quotes.

weight weight

weight defines the relative weight of this queue in comparison to other child schedulers and queues while vying for bandwidth on the parent scheduler-name. Any queues or schedulers defined as weighted receive no parental bandwidth until all policers, queues, and schedulers with a higher (numerically larger) priority on the parent have reached their maximum bandwidth or are idle.

All weight values from all weighted active queues, policers, and schedulers with a common parent scheduler are added together. Then, each individual active weight is divided by the total, deriving the percentage of remaining bandwidth provided to the queue, policer, or scheduler. A weight is considered to be active when the pertaining queue or scheduler has not reached its maximum rate and still has packets to transmit. All child policers, queues, and schedulers with a weight of 0 are considered to have the lowest priority level and are not serviced until all non-zero weighted queues, policers, and schedulers at that level are operating at the maximum bandwidth or are idle.

Values

0 to 100

Default

1

level level

The optional level parameter defines the level of hierarchy when compared to other schedulers and queues when vying for bandwidth on the parent scheduler-name. Queues or schedulers will not receive parental bandwidth until all queues and schedulers with a higher (numerically larger) priority on the parent have reached their maximum bandwidth or are idle.

Children of the parent scheduler with a lower strict priority will not receive bandwidth until all children with a higher strict priority have either reached their maximum bandwidth or are idle. Children with the same strict level are serviced relative to their weights.

Values

1 to 8

Default

1

cir-weight cir-weight

Specifies the weight the queue or scheduler will use at the within-CIR port priority level (defined by the cir-level parameter). The weight is specified as an integer value from 0 to 100 with 100 being the highest weight. When the cir-weight parameter is set to a value of 0 (the default value), the queue or scheduler does not receive bandwidth during the port schedulers within-CIR pass and the cir-level parameter is ignored. If the cir-weight parameter is 1 or greater, the cir-level parameter comes into play.

Values

0 to 100

Default

1

cir-level cir-level

Specifies the port priority the queue or scheduler will use to receive bandwidth for its within-CIR offered-load. If the cir-weight parameter is set to a value of 0 (the default value), the queue or scheduler does not receive bandwidth during the port schedulers within-CIR pass and the cir-level parameter is ignored. If the cir-weight parameter is 1 or greater, the cir-level parameter comes into play.

Values

0 to 8 (8 is the highest priority)

configure qos scheduler-policy tier scheduler parent

Description

This command defines an optional parent scheduler that is higher up the policy hierarchy. Only schedulers in tier levels 2 and 3 can have a parental association. When multiple schedulers, policers (at egress only), and/or queues share a child status with the scheduler on the parent, the weight or strict parameters define how this scheduler contends with the other children for the parent’s bandwidth. The parent scheduler can be removed or changed at any time and is immediately reflected on the schedulers created by association of this scheduler policy.

When a parent scheduler is defined without specifying weight or strict parameters, the default bandwidth access method is weight with a value of 1.

The no form of this command removes a child association with a parent scheduler. If a parent association does not currently exist, the command has no effect and returns without an error. When a parent association has been removed, the former child scheduler attempts to operate based on its configured rate parameter. Removing the parent association on the scheduler within the policy will take effect immediately on all schedulers with scheduler-name that have been created using the scheduler-policy-name.

Parameters

scheduler-name

Specifies a scheduler name. The scheduler-name must already exist within the context of the scheduler policy in a tier that is higher (numerically lower).

Values

Any valid scheduler-name existing on a higher tier within the scheduler policy.

weight weight

Specifies the relative weight of this scheduler in comparison to other child schedulers and queues at the same strict level defined by the level parameter. Within the level, all weight values from active children at that level are summed and the ratio of each active child’s weight to the total is used to distribute the available bandwidth at that level. A weight is considered to be active when the queue or scheduler the weight pertains to has not reached its maximum rate and still has packets to transmit.

A zero (0) weight value signifies that the child scheduler will receive bandwidth only after bandwidth is distributed to all other non-zero weighted children in the strict level.

Values

0 to 100

Default

1

level level

Specifies the strict priority level of this scheduler in comparison to other child schedulers and queues vying for bandwidth on the parent scheduler-name during the above-CIR distribution phase of bandwidth allocation. During the above-CIR distribution phase, any queues or schedulers defined at a lower strict level receive no parental bandwidth until all queues and schedulers defined with a higher (numerically larger) strict level on the parent have reached their maximum bandwidth or have satisfied their offered load requirements.

When the similar cir-level parameter default (undefined) are retained for the child scheduler, bandwidth is only allocated to the scheduler during the above-CIR distribution phase.

Children of the parent scheduler with a lower strict priority level will not receive bandwidth until all children with a higher strict priority level have either reached their maximum bandwidth or are idle. Children with the same strict level are serviced in relation to their relative weights.

Values

1 to 8

Default

1

cir-weight cir-weight

Specifies the relative weight of this scheduler in comparison to other child schedulers and queues at the same cir-level defined by the cir-level parameter. Within the strict cir-level, all cir-weight values from active children at that level are summed and the ratio of each active child’s cir-weight to the total is used to distribute the available bandwidth at that level. A cir-weight is considered to be active when the queue or scheduler that the cir-weight pertains to has not reached the CIR and still has packets to transmit.

A zero (0) cir-weight value signifies that the child scheduler will receive bandwidth only after bandwidth is distributed to all other non-zero weighted children in the strict cir-level.

Values

0 to 100

Default

1

cir-level cir-level

Specifies the strict priority CIR level of this scheduler in comparison to other child schedulers and queues vying for bandwidth on the parent scheduler-name during the within-CIR distribution phase of bandwidth allocation. During the within-CIR distribution phase, any queues or schedulers defined at a lower strict CIR level receive no parental bandwidth until all queues and schedulers defined with a higher (numerically larger) strict CIR level on the parent have reached their CIR bandwidth or have satisfied their offered load requirements.

If the scheduler’s cir-level parameter retains the default (undefined) state, bandwidth is only allocated to the scheduler during the above-CIR distribution phase.

Children with the same strict cir-level are serviced according to their cir-weight.

configure service customer multi-service-site egress scheduler-override scheduler parent

configure service customer multi-service-site ingress scheduler-override scheduler parent

Description

This command overrides the scheduler’s parent weight and CIR weight information. The weights apply to the associated level or cir-level configured in the applied scheduler policy. The scheduler name must exist in the scheduler policy applied to the ingress or egress of the SAP or multi-service site.

The override weights are ignored if the scheduler does not have a parent command configured in the scheduler policy. This allows the parent of the scheduler to be removed from the scheduler policy without having to remove all of the SAP/MSS overrides. If the parent scheduler does not exist causing the configured scheduler to be fostered on an egress port scheduler, the override weights will be ignored and the default values used; this avoids having non-default weightings for fostered schedulers.

The no form of the command returns the scheduler’s parent weight and CIR weight to the value configured in the applied scheduler policy.

Default

no parent

Parameters

weight

Specifies the relative weight of this scheduler in comparison to other child schedulers and queues at the same strict level defined by the level parameter in the applied scheduler policy. Within the level, all weight values from active children at that level are summed and the ratio of each active child’s weight to the total is used to distribute the available bandwidth at that level. A weight is considered to be active when the policer, queue or scheduler the weight pertains to has not reached its maximum rate and still has packets to transmit. A 0 (zero) weight value signifies that the child scheduler will receive bandwidth only after bandwidth is distributed to all other non-zero weighted children in the strict level.

Values

0 to 100

Default

1

cir-weight

Specifies the relative weight of this scheduler in comparison to other child schedulers and queues at the same cir-level defined by the cir-level parameter in the applied scheduler policy. Within the strict cir-level, all cir-weight values from active children at that level are summed and the ratio of each active child’s cir-weight to the total is used to distribute the available bandwidth at that level. A cir-weight is considered to be active when the policer, queue or scheduler that the cir-weight pertains to has not reached the CIR and still has packets to transmit.

Description

This command determines the expected location of the parent schedulers for queues configured with a parent command within the sap-egress policy. All parent schedulers must be configured within a scheduler-policy applied at the location corresponding to the parent-location parameter.

If a parent scheduler name does not exist at the specified location, the queue will not be parented and will be orphaned.

The no form of this command reverts to the default.

Default

parent-location default

Parameters

default

When the sap-egress policy is applied to an sla-profile for a subscriber, the parent schedulers of the queues need to be configured in the scheduler-policy applied to the subscriber’s sub-profile.

When the sap-egress policy is applied to a SAP, the parent schedulers of the queues need to be configured in the scheduler-policy applied to the SAP or the multiservice site.

sla

When the sap-egress policy is applied to an sla-profile for a subscriber, the parent schedulers of the queues need to be configured in the scheduler-policy applied to the same sla-profile.

If this parameter is configured within a sap-egress policy that is applied to any object except of the egress of an sla-profile, the configured parent schedulers will not be found and so the queues will not be parented and will be orphaned. This parameter is not supported when policers-hqos-manageable is configured in the SAP egress QoS policy.

Description

This command determines the expected location of the parent schedulers for the tier 1 schedulers configured with a parent command within the scheduler-policy. The parent schedulers must be configured within a scheduler-policy applied at the location corresponding to the parent-location parameter.

If a parent scheduler name does not exist at the specified location, the schedulers will not be parented and will be orphaned.

The configuration of parent-location and frame-based-accounting in a scheduler policy is mutually exclusive in order to ensure consistency between the different scheduling levels.

The no form of this command reverts to the default.

Default

parent-location none

Parameters

none

This parameter indicates that the tier 1 schedulers do not have a parent scheduler and the configuration of the parent under a tier 1 scheduler is blocked. Conversely, this parameter is blocked when any tier 1 scheduler has a parent configured.

sub

When the scheduler-policy is applied to an sla-profile for a subscriber, the parent schedulers of the tier 1 schedulers need to be configured in the scheduler-policy applied to the subscriber’s sub-profile.

If this parameter is configured within a scheduler-policy that is applied to any object except for the egress of an sla-profile, the configured parent schedulers will not be found and so the tier 1 schedulers will not be parented and will be orphaned.

vport

When the scheduler-policy is applied to an sla-profile, a sub-profile for a subscriber, or to the egress of a pseudowire SAP, the parent schedulers of the tier 1 schedulers need to be configured in the scheduler-policy applied to the Vport to which the subscriber will be assigned.

If this parameter is configured within a scheduler-policy that is applied to any object except for the egress of an sla-profile or sub-profile, or to the egress of a PW SAP, the configured parent schedulers will not be found and so the tier 1 schedulers will not be parented and will be orphaned.

Description

This command creates the buffer allocation mapping between the associated class pool and the specified mid-pool. Use care when selecting a mid-pool in an active state (properly mapped to a root-pool with a non-zero allocation percentage). If a port-class pool is parented by an inactive mid-pool, the queues using the port-class pool are forced into an operational MBS setting of 0, causing all packet to be discarded. A port-class pool can be made inactive (no available buffers) by executing parent-mid-pool none in the port-class pool context.

The no form of the command reverts to the class-pool parenting value. For the standard port-class pools, this default is 1. For alternate port-class pools the default is none.

Default

alt-port-class-pools: none

std-port-class-pools: 1

Parameters

mid-pool-id

Specifies the mid-pool identifier in the HS pool policy. Either a valid mid-pool ID or none must be specified when executing the parent-mid-pool command. The mid-pool-id parameter defines the parent mid-pool to which the port-class is associated. The none keyword deactivates the port-class pool, causing the pool to have a zero size. A queue can still map to an inactive port-class pool although all packets are discarded by the queue.

Description

This command creates a buffer allocation mapping between the associated mid-pool mid-pool-id and the specified parent-root-pool root-pool-id. The specified root pool ID must have a non-zero allocation-weight or the command fails. After a mid-pool is successfully associated with a root-pool, the parent root-pool’s allocation-weight value cannot be set to zero.

When the root-pool-id is set to none, no buffers are assigned to the mid-tier pool.

The no form of the command reverts to the default.

Description

This command configures the partner down delay time. Since the DHCP lease synchronization failure can be caused by the failure of the intercommunication link (and not necessary the entire node), there is a possibility the redundant DHCP servers become isolated in the network. In other words, they can serve DHCP clients but they cannot synchronize the lease. This can lead to duplicate assignment of IP addresses, since the servers have configured overlapping IP address ranges but they are not aware of each other’s leases.

The purpose of the partner down delay is to prevent the IP lease duplication during the intercommunication link failure by not allowing new IP addresses to be assigned from the remote IP address range. This timer is intended to provide the operator with enough time to remedy the failed situation and to avoid duplication of IP addresses or prefixes during the failure.

During the partner-down-delay time, the prefix designated as remote is eligible only for renewals of the existing DHCP leases that have been synchronized by the peering node. Only after the sum of the partner-down-delay and the maximum-client-lead-time will the prefix designated as remote be eligible for delegation of the new DHCP leases. When this occurs, we say that the remote IP address range has been taken over.

It is possible to expedite the takeover of a remote IP address range so that the new IP leases can start being delegated from that range shortly after the intercommunication failure is detected. This can be achieved by configuring the partner-down-delay timer to 0 seconds, along with enabling the ignore-mclt-on-takeover CLI flag. Caution must be taken before enabling this functionality. It is safe to bypass safety timers (partner-down-delay + MCLT) only in cases where the operator is certain that the intercommunication between the nodes has failed due to the entire node failure and not due to the intercommunication (MCS) link failure. Failed intercommunication due to the nodal failure would ensure that only one node is present in the network for IP address delegation (as opposed to two isolated nodes with overlapping IP address ranges where address duplication can occur). For this reason, the operator must ensure that there are redundant paths between the nodes to ensure uninterrupted synchronization of DHCP leases.

In access-driven mode of operation, partner-down-delay has no effect.

The no form of this command reverts to the default.

Default

partner-down-delay hrs 23 min 59 sec 59
