Command Modes Interface configur ation mode
Usage Guidelines Configuring priorities for authentication methods allows a higher priority method (not currently
running) to interrupt an authentication in progress with a lower priority method. Alternatively, if the
client is already authenticated, an interrupt from a higher priority method can cau se a client, which was
previously authenticated using a lower priority method, to reauthenticate.
The default priority of a method is equivalent to its position in the order of execution list. If you do not
configure a priority, the relative priorities (highest first) are dot1x, MAB and then webauth. If you enter
the authentication o rder command, the default priorities are the same as the configured order.
You can verify your settings with the show authentication privileged EXEC command.
