3 Web-based Management
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 value is
in the range of 1 to 65535, and is set to 60 seconds by default.
Tx Period Set the transmission timer, and is triggered in two cases. The first case
is when the client requests 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 which cannot request for
authentication actively. The switch sends multicast request/identity
packets periodically through the port enabled by 802.1x function. In
this case, this timer sets the interval to send the multicast
request/identity packets. It is in the range of 1 to 65535; the default
value is 30 seconds.
Supplicant Timeout: Set 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 switch sends
another request/challenge packet to the supplicant system if the
switch does not receive any response from the supplicant system
when this timer times out. It is in the range of 1 to 300; the default
value is 30 seconds.
Server Timeout Set 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 any response from the radius server when this timer times out.
It is in the range of 1 to 300; the default value is 30 seconds.
Max Request Count Set the maximum number of times that a switch sends authentication
request packets to a user. It is in the range of 1 to 10, and the default
value is 2.
Reauth Period Set re-authentication interval in second. After this timer expires, the
switch indicates: 802.1x re-authentication. It is in the range of 60 to
7200; the default value is 60 seconds.
Guest VLAN Can choose a guest VLAN on the switch to provide limited services to
clients, such as downloading. By default, there is none guest VLAN.
When enabling a guest VLAN on an IEEE 802.1x port, the switch assigns the client port to a guest
VLAN in case that the switch does not receive any response to its EAP request/identity frame, or
EAPOL packets are not sent by the client. The switch allows the client that is failed in
authentication to access the guest VLAN, regardless of whether EAPOL packets have been
detected. However, access to external ports out of guest VLAN still needs to be authorized.
