PurposeCommand or Action
Specifies the port to be configured, and enter interface configuration
mode.
interface interface-id
Example:
Switch(config)# interface
Step 2
gigabitethernet2/0/1
Enables periodic re-authentication of the client, which is disabled by
default.
authentication periodic
Example:
Switch(config-if)# authentication
Step 3
The default value is 3600 seconds. To change the value of the
reauthentication timer or to have the switch use a
RADIUS-provided session timeout, enter the authentication
timer reauthenticate command.
Note
periodic
Sets the number of seconds between re-authentication attempts.authentication timer {{[inactivity |
reauthenticate | restart]} {value}}
Step 4
The authentication timer keywords have these meanings:
Example:
Switch(config-if)# authentication
inactivityInterval in seconds after which if there is no activity
from the client then it is unauthorized
reauthenticateTime in seconds after which an automatic
re-authentication attempt is initiated
timer reauthenticate 180
restart valueInterval in seconds after which an attempt is made
to authenticate an unauthorized port
This command affects the behavior of the switch only if periodic
re-authentication is enabled.
Returns to privileged EXEC mode.end
Example:
Switch(config-if)# end
Step 5
Changing the Quiet Period
When the switch cannot authenticate the client, the switch remains idle for a set period of time and then tries
again. The authentication timer inactivity interface configuration command controls the idle period. A failed
authentication of the client might occur because the client provided an invalid password. You can provide a
faster response time to the user by entering a number smaller than the default.
Beginning in privileged EXEC mode, follow these steps to change the quiet period. This procedure is optional.
