vpls ignore-ac-state

Function

The vpls ignore-ac-state command prevents the status of a VSI from being affected by the status of the Attachment Circuit (AC).

Usage Guidelines

Usage Scenario

The vpls ignore-ac-state command is used only before a service switchover between a new network and an old one. Before the devices on an old VPLS network switch to a new network, if you want to check whether the VSI on the new VPLS network can work normally, you can run this command to configure the VSI to ignore the AC status so that the VSI maintains the Up state before the switchover.

Precautions

After the vpls ignore-ac-state command is executed, a VSI can keep Up if the VSI PW is Up, and the VSI status is not affected by the AC status.

The AC status refers to the status of the physical or logical interface bound to the VSI.

After the devices on the old network switch to a new network, run the undo vpls ignore-ac-state command to restore the default setting.
