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.
To set the maximum number of authentication request attempts:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Set the maximum number of
attempts for sending an
authentication request.
dot1x retry max-retry-value
Optional.
The default setting is 2.
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.
To set the 802.1X authentication timeout timers:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Set the client timeout
timer.
dot1x timer supp-timeout
supp-timeout-value
Optional.
The default is 30 seconds.
3. Set the server timeout
timer.
dot1x timer server-timeout
server-timeout-value
Optional.
The default is 100 seconds.
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
