Configuring the Timers
Used in Centralized MAC
Address Authentication
The following timers are used in centralized MAC address authentication:
■ Offline detect timer, which sets the time interval for a switch to test whether a user
goes offline. Upon detecting a user is offline, a switch notifies the RADIUS server
of the user to trigger the RADIUS server to stop the accounting on the user.
■ Quiet timer, which sets the quiet period for a switch. After a user fails to pass the
authentication performed by a switch, the switch quiets for a specific period (the
quiet period) before it authenticates users again.
■ Server timeout timer. During authentication, the switch prohibits the user from
accessing the network through the corresponding port if the connection between
the switch and RADIUS server times out.
Table 160 lists the operations to configure the timers used in centralized MAC address
authentication.
