Drag and drop the snippets into the code blanks to build a script that enables the failover Ethernet port when the primary port fails, and shuts down the failover port when the primary port returns to service.

A primary-port down event should issue `no shutdown` on the backup interface so it can carry traffic. When the primary interface returns to the up state, the backup interface should receive `shutdown` to return it to standby."} reuse={false} />
