Configuring the online user handshake feature
The online user handshake feature checks the connectivity status of online 802.1X users. The network
access device sends handshake messages to online users at the interval specified by the dot1x timer
handshake-period command. If no response is received from an online user after the access device has
made the maximum handshake attempts (set by the dot1x retry command), the device sets the user to the
offline state.
If the network has 802.1X clients that cannot exchange handshake packets with the network access
device, disable the online user handshake feature to prevent their connections from being
inappropriately torn down.

Configuring the authentication trigger feature
The authentication trigger feature enables the network 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")
.
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:
