no authentication priority
Syntax Description
Command Default The default order is dot1x, MAB, then webauth.
Command Modes Interface configuration mode
Command History
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 cause 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 order command, the default priorities are the same as the configured order.
You can verify your settings with the show authentication privileged EXEC command.
