AMS warm standby

One service interface can be the backup interface for multiple service interfaces. This feature is called AMS warm standby. To make a service interface the backup for multiple service interfaces, you configure an AMS interface for each service interface you want to protect. Each of these AMS interfaces has two member interfaces-a primary member interface, which is the service interface you want to protect, and the secondary member interface, which is the backup service interface. You can use the same secondary member interface in multiple AMS interfaces. To configure a warm-standby AMS interface, include the primary mams-a/b/0 statement and the secondary mams-a/b/0 statement at the [edit interfaces amsn redundancy-options] hierarchy level. If you use redundancy-options in an AMS interface, you cannot use load-balancing-options in the same AMS interface. You cannot use the same member interface in both an AMS interface that includes load-balancing-options and an AMS interface that includes redundancy-options. To show the state of an AMS interface configured with warm standby, issue the show interfaces redundancy command. To switch from the primary interface to the secondary interface, issue the request interface switchover amsn command. To revert to the primary interface from the secondary interface, issue the request interface revert amsn command.
