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 depreca ted in
Cisco IOS Release 12.2(50)SG and la ter 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 m ethod.
You can verify your settings with the show authentication privileged EXEC command.
