authentication timer
Note You should change the default values of this command only to adjust for unusual circumstances such as
unreliable links or specific behavioral problems with certain clients or authentication servers.
During the inactivity period, the Ethernet switch network module does not accept or initiate any
authentication requests. If you want to provide a faster response time to the user, enter a number less
than the default.
The reauthenticate keyword affects the behavior of the Ethernet switch network module only if you
have enabled periodic reauthentication with the authentication reauthentication global configuration
command.
Examples The following example shows how to specify that the reauthentication period value for the client should
be obtained from the authentication, authorization, and accounting (AAA) server as Session-Timeout
(RADIUS Attribute 27):
Switch(config-if)# authentication timer reauthenticate server
Switch(config-if)#
