Setting The Maximum Number Of Authentication Request Attempts; Setting The 802.1X Authentication Timeout Timers; Configuring The Online User Handshake Function - HP 5120 EI Switch Series Configuration Manual

Setting the maximum number of authentication request attempts

The network access device retransmits an authentication request if it receives no response to the request it
has sent to the client within a period of time (specified by using the dot1x timer tx-period tx-period-value
command or the dot1x timer supp-timeout supp-timeout-value command). The network access device
stops retransmitting the request, if it has made the maximum number of request transmission attempts but
still received no response.
Follow these steps to set the maximum number of authentication request attempts:

Setting the 802.1X authentication timeout timers

The network device uses the following 802.1X authentication timeout timers:
 Client timeout timer—Starts when the access device sends an EAP-Request/MD5 Challenge packet
to a client. If no response is received when this timer expires, the access device retransmits the
request to the client.
Server timeout timer—Starts when the access device sends a RADIUS Access-Request packet to the

authentication server. If no response is received when this timer expires, the access device
retransmits the request to the server.
You can set the client timeout timer to a high value in a low-performance network, and adjust the server
timeout timer to adapt to the performance of different authentication servers. In most cases, the default
settings are sufficient.
Follow these steps to set the 802.1X timers:

Configuring the online user handshake function

About 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.
