Usage Guidelines
Ordering sets the order of methods that the switch attempts when trying to authenticate a new device is
connected to a port.
When configuring multiple fallback methods on a port, set web authentication (webauth) last.
Assigning priorities to different authentication methods allows a higher-priority method to interrupt an
in-progress authentation method with a lower priority.
Note
If a client is already authenticated, it might be reauthenticated if an interruption from a higher-priority
method occurs.
The default priority of an authentication method is equivalent to its position in execution-list order:
802.1x authentication, MAC authentication bypass, and web authentication. Use the
dot1x
,
mab
, and
webauth
keywords to change this default order.
Examples
This example shows how to set 802.1x as the first authentication method and web authentication as the
second authentication method:
Switch(config)#
authentication priority dotx webauth
dot1x
Add 802.1x to the order of authentication methods.
mab
Add MAC authentication bypass (MAB) to the order of authentication
methods.
webauth
Add web authentication to the order of authentication methods.
