To apply SVI Autostate Exclude, perform this task:
Command
Step 1
Switch# configure terminal
Step 2
Switch(config)# interface interface-id
Step 3
Switch(config-if)# switchport autostate exclude
Step 4
Switch(config)# end
Step 5
Switch# show run interface
Step 6
Switch# show interface switchport
This example shows how to apply SVI Autostate Exclude on interface g3/1:
