Mixed Authentication Modes
Use l2-auth-fail-through command to perform mixed authentication which includes both MAC and 802.1x
authentication. When MAC authentication fails, enable the
l2-auth-fail-through command to perform
802.1x authentication.

Advanced Configuration Options for 802.1x
This section describes advanced configuration options for 802.1x authentication.
Configuring reauthentication with Unicast Key Rotation
When enabled, unicast and multicast keys are updated after each reauthorization. It is a best practice to
configure the time intervals for reauthentication, multicast key rotation, and unicast key rotation to be at least 15
minutes. Make sure these intervals are mutually prime, and the factor of the unicast key rotation interval and the
multicast key rotation interval is less than the reauthentication interval.
The following is an example of the parameters you can configure for reauthentication with unicast and multicast
key rotation:
Reauthentication: Enabled
Reauthentication Time Interval: 6011 Seconds
Multicast Key Rotation: Enabled
Multicast Key Rotation Time Interval:1867 Seconds
NOTE: By default the l2-auth-fail-through command is disabled.

NOTE: Unicast key rotation depends upon both the AP/controller and wireless client behavior. It is known that some wireless NICs
have issues with unicast key rotation.
