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:
