Configuring the online user handshake function

The online user handshake function 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 maximum number
of handshake attempts (set by the dot1x retry command) has been made, the network access device sets
the user in the offline state.
If iNode clients are deployed, you can also enable the online handshake security function to check for
802.1X users that use illegal client software to bypass security inspection such as proxy detection and
dual network interface cards (NICs) detection. This function checks the authentication information in
client handshake messages. If a user fails the authentication, the network access device logs the user off.

Configuration guidelines

Follow these guidelines when you configure the online user handshake function:
To use the online handshake security function, make sure the online user handshake function is
•
enabled. HP recommends that you use the iNode client software and IMC server to ensure the
normal operation of the online user handshake security function.
• If the network has 802.1X clients that cannot exchange handshake packets with the network access
device, disable the online user handshake function to prevent their connections from being
inappropriately torn down.
You must disable proxy detection before disabling the online user handshake function.
