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.
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 History
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.
Use the action command to specify the type of action to be taken when the action is violated.
The configured action has no impact if the MAC limit has not been reached.

Enters L2VPN bridge group bridge domain MAC configuration mode.
Configures the specified action when the number of MAC addresses learned on a bridge is reached.
Specifies the type of notification that is sent when the number of learned MAC addresses exceeds the configured limit.
pw-class (VFI)
To configure the pseudowire class template name to use for the pseudowire, use the pw-class command in L2VPN bridge group bridge domain VFI pseudowire configuration mode. To delete the pseudowire class, use the no form of this command.

Syntax Description
Command History
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.
In general, the type is set to inactivity. With an inactivity type configuration, a MAC address is removed from the forwarding table after the MAC address is inactive for the configured aging time.
With an absolute type configuration, a MAC address is always removed from the forwarding table after the aging time has elapsed once it is initially learned.
Task ID
Examples
The following example shows how to configure the MAC address aging type to absolute for every member of the bridge domain named bar:
RP/0/0/CPU0:router# configure RP/0/0/CPU0:router(config)# l2vpn RP/0/0/CPU0:router(config-l2vpn)# bridge group 1 RP/0/0/CPU0:router(config-l2vpn-bg)# bridge-domain bar RP/0/0/CPU0:router(config-l2vpn-bg-bd)# mac RP/0/0/CPU0:router(config-l2vpn-bg-bd-mac)# aging RP/0/0/CPU0:router(config-l2vpn-bg-bd-mac-aging)# type absoluteRelated Commands
