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 guarantee 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.

5. Enable the online handshake
security function.
dot1x handshake secure
Optional.
By default, the function is disabled.
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
