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.

• Disable the multicast trigger in a wireless LAN. Wireless clients and the wireless module of the access device can both 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.
