response within a period of time. This process continues until the maximum number of request
attempts set with the dot1x retry command (see ―Setting the maximum number of authentication
request attempts‖) is reached.
The identity request timeout timer sets both the identity request interval for the multicast trigger and the
identity request timeout interval for the unicast trigger.
Configuration guidelines
Follow these guidelines when you configure the authentication trigger function:
 Enable the multicast trigger on a port when the clients attached to the port cannot send EAPOL-Start
packets to initiate 802.1X authentication.
 Enable the unicast trigger on a port if only a few 802.1X clients are attached to the port and these
clients cannot initiate authentication.
 To avoid duplicate authentication packets, do not enable both triggers on a port.

Specifying a mandatory authentication domain on a port
You can place all 802.1X users in a mandatory authentication domain for authentication, authorization,
and accounting on a port. No user can use an account in any other domain to access the network
through the port. The implementation of a mandatory authentication domain enhances the flexibility of
802.1X access control deployment.
