show interfaces
This is an example of output from the show interfaces switchport backup command:
Switch# show interfaces switchport backup
Switch Backup Interface Pairs:
Active Interface Backup Interface State
--------------------------------------------------------------
Fa1/0/1 Fa1/0/2 Active Up/Backup Standby
Fa3/0/3 Fa4/0/5 Active Down/Backup Up
Po1 Po2 Active Standby/Backup Up
This is an example of output from the show interfaces interface-id pruning command:
Switch# show interfaces gigibitethernet1/0/2 pruning
Port Vlans pruned for lack of request by neighbor
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 Gi1/0/6 goes down, Gi1/0/8 carries all
VLANs of the Flex Link pair.
Switch# show interfaces switchport backup
Switch Backup Interface Pairs:
Active Interface Backup Interface State
------------------------------------------------------------------------
GigabitEthernet1/0/6 GigabitEthernet1/0/8 Active Down/Backup Up
Vlans Preferred on Active Interface: 1-50
Vlans Preferred on Backup Interface: 60, 100-120
This is an example of output from the show interfaces switchport backup command. In this example,
VLANs 1 to 50, 60, and 100 to 120 are configured on the switch:
Switch(config)# interface gigabitEthernet 1/0/6
Switch(config-if)# switchport backup interface gigabitEthernet 1/0/8 prefer vlan
60,100-120
When both interfaces are up, Gi1/0/8 forwards traffic for VLANs 60, 100 to 120, and Gi1/0/6 will
forward traffic for VLANs 1 to 50.

Vlans on Interface Gi 1/0/6: 1-50
Vlans on Interface Gi 1/0/8: 60, 100-120
Voice VLAN Displays the VLAN ID on which voice VLAN is enabled.
Appliance trust Displays the class of service (CoS) setting of the data packets
of the IP phone.
