Parameters
handshake-period handshake-period-value : Sets the handshake timer. This timer sets the
handshake-period and is triggered after a supplicant system passes the authentication. It sets the
interval for a switch to send handshake request packets to online users. If you set the number of retries
to N by using the dot1x retry command, an online user is considered offline when the switch does not
receive response packets from it in a period N times of the handshake-period.
The handshake-period-value argument ranges from 5 to 1,024 (in seconds). By default, the handshake
timer is set to 15 seconds.
quiet-period quiet-period-value : Sets the quiet-period timer. This timer sets the quiet-period. When a
supplicant system fails to pass the authentication, the switch quiets for the set period (set by the
quiet-period timer) before it processes another authentication request re-initiated by the supplicant
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 1 to 120 (in seconds). By default, the transmission timer is
set to 30 seconds.
