The evpn-vpws ignore-ac-state command enables the function to ignore the attachment circuit (AC) status on an interface.
The undo evpn-vpws ignore-ac-state command disables the function to ignore the AC status on an interface.
By default, the function to ignore the attachment circuit (AC) status on an interface is disabled.

Usage Scenario
In an EVPN VPWS active/standby link networking, configure association between the detection mechanism and AC interfaces. When the AC interface goes Down, the peer AC interface also goes Down, triggering a primary/backup link switchover. To ensure that EVPN VPWS services are not interrupted, run the evpn-vpws ignore-ac-state command on the AC interface to enable the interface to ignore the AC status. In this way, EVPN VPWS services do not need to be reestablished during a primary/secondary link switchover.
Prerequisites
An EVPL instance has been bound to the AC interface using the evpl instance command.
