configure service vpls proxy-arp table-size

Description

This command adds a table-size limit per service. By default, the table-size limit is 250; it can be set up to 16k entries per service. A non-configurable implicit high watermark of 95% and low watermark of 90% exists, per service and per system. When those watermarks are reached, a syslog/trap is triggered. When the system/service limit is reached, entries for a specified IP can be replaced (a different MAC can be learned and added) but no new IP entries will be added, regardless of the type (Static, evpn, dynamic). If the user attempts to change the table-size value to a value that cannot accommodate the number of existing entries, the attempt will fail.

Default

configure card virtual-scheduler-adjustment task-scheduling-int

Description

This command overrides the system default time between scheduling the hierarchical virtual scheduling task. By default, the system "wakes” the virtual scheduler task every 50ms; this is equivalent to five 10ms timer ticks. The task-scheduling-int command uses a percent value parameter to modify the number of timer ticks.

While the system accepts a wide range of percent values, the result is rounded to the nearest 10ms tick value. The fastest wake interval is 10ms (1 timer tick).

The no form of this command restores the default task scheduling interval of the card’s hierarchical virtual scheduler task.

Parameters

percent-of-default:

Specifies that the percent-of-default parameter is required and is used to modify the default task scheduling interval for the hierarchical virtual scheduling task on the card. Defining 100.00 percent is equivalent to removing the override.

Values

Full Context

configure system grpc tcp-keepalive

Description

Commands in this context configure the sending of TCP keepalives by the router towards all gRPC clients.

Enabling TCP keepalive speeds up the detection of certain failures. The TCP keepalives sent by the router are controlled by three commands: idle-time, interval, and retries. The router starts sending TCP keepalives when the connection has been idle (no TCP segments sent or received) for more than idle-time seconds. At that point, the router sends a probe (TCP ACK with a sequence number = current sequence number - 1) and expects a TCP ACK. It repeats this probe every interval seconds for the configured number of retries. If no response is received to any of the probes, the connection is immediately closed, which starts the purge timer if the TCP connection is currently supporting the RibApi service.

Description

This command configures an override for the TCP maximum segment size to use with a specific peer or set of peers (depending on the scope of the command).

The configured value controls two properties of the TCP connection as follows:

• TCP MSS option — The router advertises the TCP MSS option value in the TCP SYN packet it sends as part of the 3-way handshake. The advertised value may be lower than the configured value, depending on the IP MTU of the first hop IP interface. The peers are asked to abide by this value when sending TCP segments to the local router.

• TCP maximum segment size — The actual transmitted size may be lower than the configured value, depending on the TCP MSS option value signaled by the peers, the effect of path MTU discovery, or other factors.

The no form of this command removes the TCP MSS override values from the configuration.

Default

no tcp-mss

Parameters

mss-value

Specifies the The router uses the TCP SYN to advertise the TCP MSS option value towards its peer. MSS value, in bytes, to use with the peers that fall within the scope of the command.

configure application-assurance group policy app-qos-policy entry action tcp-validate

Description

This command assigns an existing TCP validation policy as an action on flows matching this AQP entry.

tcp-validate can only be called from AQP entries that:

• have no matching conditions that relate to information extracted from the incoming IP packets; for example, no application or IP address.

• allow the following match conditions:

  • none

  • aa-sub

  • characteristic

  • traffic-direction (both only)

    traffic-direction cannot be unidirectional (from or to sub). It can either be set to both or left unspecified.

The no form of this command removes the TCP validation policy action from flows matching this AQP entry.

configure router rsvp te-down-threshold

Description

This command configures the specific threshold levels per node and per interface. Threshold levels are for reserved bandwidth per interface. The te-threshold-update command is used to enable or disable threshold-based IGP TE updates. Any reserved bandwidth change per interface is compared with all the threshold levels and trigger an IGP TE update if a defined threshold level is crossed in either direction (LSP setup or teardown). Threshold-based updates must be supported with both ISIS and OSPF. A minimum of one and a maximum of 16 threshold levels is supported.

Threshold levels configured per node is inherited by all configured RSVP interfaces. Threshold levels defined under the RSVP interface is used to trigger IGP updates if non-default threshold levels are configured.

The no form of this command resets te-down-threshold to its default value.

Default

no te-down-threshold (equals following values 100 99 98 97 96 95 90 85 80 75 60 45 30 15 0)

configure router mpls interface te-metric

Description

This command configures the TE metric used on the interface. This metric is in addition to the interface metric used by IGP for the shortest path computation.

This metric is flooded as part of the TE parameters for the interface using an opaque LSA or an LSP. The IS-IS TE metric is encoded as sub-TLV 18 as part of the extended IS reachability TLV. The metric value is encoded as a 24-bit unsigned integer. The OSPF TE metric is encoded as a sub-TLV Type 5 in the Link TLV. The metric value is encoded as a 32-bit unsigned integer.

When the use of the TE metric is enabled for an LSP, CSPF will first prune all links in the network topology which do not meet the constraints specified for the LSP path. Such constraints include bandwidth, admin-groups, and hop limit. Then, CSPF will run an SPF on the remaining links. The shortest path among the all SPF paths will be selected based on the TE metric instead of the IGP metric which is used by default.

The TE metric in CSPF LSP path computation can be configured by entering the command config>router>mpls>lsp>metric-type te.

Note that the TE metric is only used in CSPF computations for MPLS paths and not in the regular SPF computation for IP reachability.

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

Default

no te-metric

The value of the IGP metric is advertised in the TE metric sub-TLV by IS-IS and OSPF.

Description

This command enables the non-owner master to reply to TCP port 23 Telnet requests directed at the virtual router instances’ IP addresses.

Non-owner virtual router instances are limited by the VRRP specifications to responding to ARP requests destined to the virtual router IP addresses and routing IP packets not addressed to the virtual router IP addresses. Many network administrators find this limitation frustrating when troubleshooting VRRP connectivity issues.

This limitation can be disregarded for certain applications. Ping, SSH and Telnet can each be individually enabled or disabled on a per-virtual-router-instance basis.

The telnet-reply command enables the non-owner master to reply to Telnet requests directed at the virtual router instances’ IP addresses. The Telnet request can be received on any routed interface. Telnet must not have been disabled at the management security level (either on the parental IP interface or based on the Telnet source host address). Correct login and CLI command authentication is still enforced.

configure service template vpls-template temp-flooding

Description

The temporary flooding is designed to minimize failover times by eliminating the time it takes to flush the MAC tables and if MVRP is enabled the time it takes for MVRP registration. Temporary flooding is initiated only upon xSTP TCN reception. During this procedure while the MAC flush takes place the frames received on one of the VPLS SAPs/pseudowires are flooded in a VPLS context which for MVRP case includes also the unregistered MVRP trunk ports. The MAC Flush action is initiated by the STP TCN reception or if MVRP is enabled for the data VPLS, by the reception of a MVRP New message for the SVLAN ID associated with the data VPLS. As soon as the MAC Flush is done, regardless of whether the temp-flooding timer expired or not, traffic will be delivered according to the regular FDB content which may be built from MAC Learning or based on MVRP registrations. This command provides a flood-time value that configures a fixed amount of time, in seconds, during which all traffic is flooded (BUM or known unicast) as a safety mechanism. Once the flood-time expires, traffic will be delivered according to the regular FDB content which may be built from MAC Learning or based on MVRP registrations. The temporary flooding timer should be configured in such a way to allow auxiliary processes like MAC Flush, MMRP and/or MVRP to complete/converge. The temporary flooding behavior applies to regular VPLS, VPLS instantiated with VPLS-template, IVPLS and BVPLS when MMRP is disabled.

The no form of this command disables the temporary flooding behavior.

[Tree] (config>router>route-next-hop-policy template)

Full Context

configure router route-next-hop-policy template

Description

This command creates a template to configure the attributes of a Loop-Free Alternate (LFA) Shortest Path First (SPF) policy. An LFA SPF policy allows the user to apply specific criteria, such as admin group and SRLG constraints, to the selection of an LFA backup next-hop for a subset of prefixes that resolve to a specific primary next-hop.

The user first creates a route next-hop policy template under the global router context and then applies it to a specific OSPF or IS-IS interface in the global routing instance or in a VPRN instance.

A policy template can be used in both IS-IS and OSPF to apply the specific criteria to prefixes protected by LFA. Each instance of IS-IS or OSPF can apply the same policy template to one or more interface.

The commands within the route next-hop policy template use the begin-commit-abort model. The following are the steps to create and modify the template:

To create a template, the user enters the name of the new template directly under the route-next-hop-policy context.

1. To delete a template that is not in use, the user enters the no form for the template name under the route-next-hop-policy context.

2. The user enters the editing mode by executing the begin command under the route-next-hop-policy context. The user can then edit and change any number of route next-hop policy templates. However, the parameter value will still be stored temporarily in the template module until the commit is executed under the route-next-hop-policy context. Any temporary parameter changes will be lost if the user enters the abort command before the commit command.

3. The user is allowed to create or delete a template instantly once in the editing mode without the need to enter the commit command. Furthermore, the abort command, if entered, will have no effect on the prior deletion or creation of a template.

Once the commit command is issued, IS-IS or OSPF will re-evaluate the templates and if there are any net changes, it will schedule a new LFA SPF to re-compute the LFA next-hop for the prefixes associated with these templates.

Parameters

name

Specifies the name of the template, up to 32 characters.

[Tree] (config>service>ipfix>ipfix-export-policy template-format)

Full Context

configure service ipfix ipfix-export-policy template-format

Description

This command selects one of two template formats that contains a set of element IDs and their interpretation in IPFIX NAT flow logging. The difference between the two formats is related to the fields conveying information about the translated source IP addresses and ports (outside IP addresses and ports). Further, format 1 conveys information about the translated source port (post NAT) in the sourceTransportPort information element while format 2 conveys this information in the postNAPTsourceTrasportPort element.

Further, format1 conveys information about the translated source port (post NAT) in the information element sourceTransportPort while a new information element postNAPTsourceTrasportPort is introduced in format2 to carry this information.

For more information about template formats, refer to "Template Formats” in the 7450 ESS, 7750 SR, and VSR Multiservice Integrated Service Adapter and Extended Services Appliance Guide, where the table lists supported information elements and their description for each format.

The no form of the command reverts to the default value.

Default

Description

Use this command to enable the router to send third-party next-hop to EBGP peers in the same subnet as the source peer, as described in RFC 4271. If enabled when an IPv4 or IPv6 route is received from one EBGP peer and advertised to another EBGP peer in the same IP subnet, the BGP next-hop is left unchanged. Third-party next-hop is not done if the address family of the transport does not match the address family of the route.

The no form of this command prevents BGP from performing any third party next-hop processing toward any single-hop EBGP peers within the scope of the command. No third-party next-hop means the next-hop will always carry the IP address of the interface used to establish the TCP connection to the peer.

Full Context

configure qos policer-control-policy tier

Description

This command is used to create, configure, and delete tiered arbiters. Two tiers are supported that always exist, specified as tier 1 and tier 2. Tiered arbiters enable the creation of a bandwidth control hierarchy for managing child policers in an arbitrary fashion. Each arbiter enables parenting of child policers within eight strict levels of priority and a maximum aggregate rate may be defined for the children that the arbiter will enforce. Arbiters created on tier 1 are automatically parented to the root arbiter that is always present. Arbiters created on tier 2 default to the root arbiter as parent but can also be explicitly parented to a tier 2 arbiter. Child policers associated with an instance of the policer-control-policy can be parented to any tiered arbiter or to the root arbiter.

Context

[Tree] (config>qos>scheduler-policy tier)

Full Context

configure qos scheduler-policy tier

Description

This command identifies the level of hierarchy that a group of schedulers are associated with. Within a tier level, a scheduler can be created or edited. Schedulers created within a tier can only be a child (take bandwidth from a scheduler in a higher tier). Tier levels increase sequentially with 1 being the highest tier. All tier 1 schedulers are considered to be root and cannot be a child of another scheduler. Schedulers defined in tiers other than 1 can also be root (parentless).

3 tiers (levels 1, 2, and 3) are supported.

The save config and show config commands only display information on scheduler tiers that contain defined schedulers. When all schedulers have been removed from a level, that level ceases to be included in output from these commands.

Parameters

tier

This parameter is required to indicate the group of schedulers to create or be edited. Tier levels cannot be created or deleted. If a value for level is given that is out-of-range, an error will occur and the current context of the CLI session will not change.
