rization, and accounting (AAA) methods for use on interfaces running IEEE 802.1X. To return to the default config-
uration, use the no form of this command.

Additional methods of authentication are used only if the previous method returns an error and not if the request
for authentication is denied. To ensure that authentication succeeds even if all methods return an error, specify
none as the final method in the command line.
