system. During this quiet period, the switch does not perform any 802.1x authentication-related actions
for the supplicant system.
The quiet-period-value argument ranges from 10 to 120 (in seconds). By default, the quiet-period timer
is set to 60 seconds.
server-timeout server-timeout-value: Sets the RADIUS server timer. This timer sets the server-timeout
period. After sending an authentication request packet to the RADIUS server, a switch sends another
authentication request packet if it does not receive the response from the RADIUS server when this
timer times out.
The server-timeout-value argument ranges from 100 to 300 (in seconds). By default, the RADIUS
server timer is set to 100 seconds.
supp-timeout supp-timeout-value: Sets the supplicant system timer. This timer sets the supp-timeout
period and is triggered by the switch after the switch sends a request/challenge packet to a supplicant
system (The packet is used to request the supplicant system for the MD5 encrypted string.) The switch
sends another request/challenge packet to the supplicant system if the switch does not receive the
response from the supplicant system when this timer times out..
The supp-timeout-value argument ranges from 10 to 120 (in seconds). By default, the supplicant
system timer is set to 30 seconds.
tx-period tx-period-value: Sets the transmission timer. This timer sets the tx-period and is triggered in
two cases. The first case is when the client requests for authentication. The switch sends a unicast
request/identity packet to a supplicant system and then triggers the transmission timer. The switch
sends another request/identity packet to the supplicant system if it does not receive the reply packet
from the supplicant system when this timer times out. The second case is when the switch
authenticates the 802.1x client who cannot request for authentication actively. The switch sends
multicast request/identity packets periodically through the port enabled with 802.1x function. In this
case, this timer sets the interval to send the multicast request/identity packets.
The tx-period-value argument ranges from 10 to 120 (in seconds). By default, the transmission timer is
set to 30 seconds.
ver-period ver-period-value: Sets the client version request timer. This timer sets the version period
and is triggered after a switch sends a version request packet. The switch sends another version
request packet if it does receive version response packets from the supplicant system when the timer
expires.
The ver-period-value argument ranges from 1 to 30 (in seconds). By default, the client version request
timer is set to 30 seconds.
Description
Use the dot1x timer command to set a specified 802.1x timer.
Use the undo dot1x timer command to restore a specified 802.1x timer to the default setting.
During an 802.1x authentication process, multiple timers are triggered to ensure that the supplicant
systems, the authenticator systems, and the Authentication servers interact with each other in an
orderly way. To make authentications being processed in the desired way, you can use the dot1x timer
command to set the timers as needed. This may be necessary in some special situations or in tough
network environments. Normally, the defaults are recommended. (Note that some timers cannot be
adjusted.)
