Configuring the authentication trigger feature
The authentication trigger feature enables the access device to initiate 802.1X authentication when
802.1X clients cannot initiate authentication.
This feature provides the multicast trigger and unicast trigger (see 802.1X authentication initiation in
"802.1X overview").
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.

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
