Usage Guidelines
By default, if 802.1X times out and if MAB fails, WebAuth is enabled.
The authentication fallback command replaces the following dot1x command, which is deprecated in
Cisco IOS Release 12.2(50)SG and later releases:
[no] dot1x fallback profile
The Webauth fallback feature allows you to have those clients that do not have an 802.1X supplicant and
are not managed devices to fall back to the WebAuth method.
You can verify your settings with the show authentication privileged EXEC command.
Examples
The following example shows how to enable WebAuth fallback and specify the fallback profile to use
when failing over to WebAuth:
Switch(config-if)# authentication fallback fallbacktest1
Switch(config-if)#
The following example shows how to disable WebAuth fallback:
Switch(config-if)# no authentication fallback fallbacktest1
Switch(config-if)#
