Cisco IOS XR Virtual Private Network Command Reference for the Cisco CRS Router, Release 4.1 - Virtual Private LAN Services Commands [Cisco Carrier Routing System]

action (VPLS)

To configure the bridge behavior when the number of learned MAC addresses reaches the MAC limit configured, use the action command in L2VPN bridge group bridge domain MAC limit configuration mode. To disable this feature, use the no form of this command.

action { flood | no-flood | shutdown }

no action { flood | no-flood | shutdown }

Syntax Description

flood	Configures the action to flood all unknown unicast packets when the MAC limit is reached. If the action is set to flood, all unknown unicast packets are flooded over the bridge.
no-flood	Configures the action to no-flood so all unknown unicast packets are dropped when the MAC limit is reached. If the action is set to no-flood, all unknown unicast packets are dropped.
shutdown	Stops forwarding when the MAC limit is reached. If the action is set to shutdown, all packets are dropped.

Command Default

No action is taken when the MAC address limit is reached.

Release	Modification
Release 3.8.0	This command was introduced.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

Table 4 show l2vpn bridge-domain summary Command Field Descriptions
Field	Description
Number of groups	Number of configured bridge domain groups is displayed.
bridge-domains	Number of configured bridge domains is displayed.
Shutdown	Number of bridge domains that are in Shutdown state is displayed.
Number of ACs	Number of attachment circuits that are in Up state and Down state are displayed.
Number of PWs	Number of pseudowires that are in Up state and Down state are displayed. This includes the VFI pseudowire and the access pseudowire.

Related Commands

Command	Description
clear l2vpn bridge-domain (VPLS)	Clears the MAC addresses and restarts the bridge domains on the router.

show l2vpn forwarding bridge-domain (VPLS)

To display information on the bridge that is used by the forwarding layer, use the show l2vpn forwarding bridge-domain command in EXEC mode.

show l2vpn forwarding bridge-domain [bridge-domain-name] { detail | hardware { egress | ingress } } location node-id

Syntax Description

bridge-domain-name	(Optional) Name of a bridge domain.
detail	Displays all the detailed information on the attachment circuits and pseudowires.
hardware	Displays the hardware location entry.
egress	Reads information from the egress PSE.
ingress	Reads information from the ingress PSE.
location node-id	Displays the bridge-domain information for the specified location. The node-id argument is entered in the rack/slot/module notation.

Command Default

None

Command History

Release	Modification
Release 3.8.0	This command was introduced.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

For each bridge, you can display summary information about the number of bridge ports, number of MAC addresses, and so forth.

The detail keyword displays detailed information on the attachment circuits and pseudowires, and is meant for field investigation by a specialized Cisco engineer.

Note

All bridge ports in the bridge domain on that line card are displayed. Therefore, if the bridge domain contains non-local bridge ports, those are displayed as well.
