action-priority

Syntax

Hierarchy Level

Description

Configure the priority for an interface on which the MAC move is applied. When a MAC move is configured with a corresponding action, and that limit is exceeded, the action is applied to one of the interfaces associated with that MAC address having the highest action priority. If the action configured for the MAC move is shutdown, you can use the action priority to determine which interface is disabled. If an interface is trusted, assign a low action priority to decrease the likelihood that the interface shuts down if the configured action is shutdown or vlan-member-shutdown.

If no action priority is configured, or if the interfaces have the same action priority, then the action is applied to the interface to which the MAC address moved last.

Options

value

Value assigned to an interface associated with a MAC address move. The value determines the priority with which an action is applied to the interface if the MAC address move limit is reached. The interface with the highest priority is the interface with the lowest value configured for action-priority.

A higher value means lower priority. For example, if a MAC address move occurs between two interfaces with the action priority value set to 5 and 6, the interface with value 5 as the action priority value is blocked.

If a VPLS instance has MAC move action enabled, set the action-priority to 8 for the router to detect an interface as a core interface by the VPLS customer edge loop prevention feature. By default, the loop prevention feature supports lsi and vt-type interfaces as core interfaces; however, you can use this special action-priority value to designate any interface as a core interface.
