This feature provides the multicast trigger and unicast trigger (see 802.1X authentication initiation in
"
").
Configuration guidelines
When you configure the authentication trigger feature, follow these guidelines:
•
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.
Configuration procedure
To configure the authentication trigger feature on a port:
Step Command

1.
Enter system view.

N/A
2.
(Optional.) Set the username
request timeout timer.
dot1x timer tx-period

4.
Enable an authentication
trigger.

}
By default, the multicast trigger is
enabled, and the unicast trigger is
disabled.
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.
