Asynchronous notification on EVPN-VPWS

You can enable the asynchronous notification command to send a loss of signal (LOS) alarm to the CE device when the circuit cross-connect link between a customer edge and provider edge device goes down. Asynchronous notification supports ethernet-ccc, ethernet-vpls, or vlan-ccc encapsulation. To enable this feature, include the asynchronous-notification statement at the [edit interfaces interface-name ] hierarchy level.
