DETAILED STEPS
To disable periodic reauthentication, use the
no
dot1x re-authentication
global configuration
command. To return to the default number of seconds between reauthentication attempts, use the
no
dot1x timeout re-authperiod
global configuration command.
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 idle time is determined by the quiet-period value. 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 smaller number than the default.
Follow these steps to change the quiet period.
