Examples
This example shows how to create a fallback profile to be used with web authentication:

Switch(config)# fallback profile profile1

Switch(config-fallback-profile)# ip admission rule1
Switch(config-fallback-profile)# exit
Switch(config)# interface gigabitethernet 1/0/1
Switch(config-if)# dot1x fallback profile1
Switch(config-if)# end
You can verify your settings by entering the show running-configuration [interface interface-id]
privileged EXEC command.
