c. Configure the timers on the
General
tab.
4 Set the user idle timeout value. The value of this field is in minutes. To prevent
the user from timing out set the value of this field to 0.
The user idle timeout is the time in minutes for which the switch maintains state of an
unresponsive client. If the client does not respond back to the switch within this time,
the switch deletes the state of the user. The user will have to re-authenticate to gain
access once the user state has been deleted. Set the value of the user idle timeout. The
value of this field is in minutes
5 Set the Authentication Server Dead Time value in minutes.
The Authentication Server Dead Time is applied only when there are two or more
authentication servers configured. The authentication Server Dead Timeout is the
maximum period for which an authentication server is proclaimed dead before being
activated again.
Scenario 1: If the authentication server is the only server.
In this case the server is never marked down and all requests are sent to this server
irrespective of the timer setting.
Scenario 2: If one or more backup servers are configured.
In this case, once the server (server A) is found to be un-responsive it is marked as
down and the subsequent requests are sent to the next server on the priority list. The
server A is marked down for the dead time after which it is brought back into the list.
If the priority of this server is higher than the server currently servicing the requests,
this server (server A) takes over. If it is still non-accessible, it will be marked down for
the Authentication Server Dead Time Period
