Configuring the authentication trigger function

The authentication trigger function enables the network access device to initiate 802.1X authentication
when 802.1X clients cannot initiate authentication.
This function provides the following types of authentication trigger:
Multicast trigger—Periodically multicasts Identity EAP-Request packets out of a port to detect 802.1X
•
clients and trigger authentication.
Unicast trigger—Enables the network device to initiate 802.1X authentication when it receives a
•
data frame from an unknown source MAC address. The device sends a unicast Identity
EAP/Request packet to the unknown source MAC address, and retransmits the packet if it has
received no response within a period of time. This process continues until the maximum number of
request attempts set with the dot1x retry command (see
authentication request
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.
