This is an example of output from the show interfaces switchport backup command:
Switch# show interfaces switchport backup
Switch Backup Interface Pairs:
This is an example of out put from the show interfaces switchport backup command when a Flex Link
interface goes down (LINK_DOWN), and VLANs preferred on this interface are moved to the peer
interface of the Flex Link pair. In this example, if interface Gi2/0/6 goes down, Gi2/0/8 carries all
VLANs of the Flex Link pair.
