Command History
Usage Guidelines The fallback profile is used to define the IEEE 802.1x fallback behavior for IEEE 802.1x ports that do
not have supplicants. The only supported behavior is to fall back to web authentication.
After entering the fallback profile command, you enter profile configuration mode, and these
configuration commands are available:
ip: Create an IP configuration.
access-group: Specify access control for packets sent by hosts that have not yet been authenticated.
admission: Apply an IP admission rule.
Examples This example shows how to create a fallback profile to be used with web authentication:
Switch# configure terminal
Switch(config)# ip admission name rule1 proxy http
Switch(config)# fallback profile profile1
Switch(config-fallback-profile)# ip access-group default-policy in
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.
profile Specify the fallback profile for clients that do not support IEEE 802.1x
authentication.
