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.
If a client is already authenticated, it might be reauthenticated if an interruption from a higher-priority
Note
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.
