37.2.7 Changing the QUIET Time
When user authentication fails, the device does not allow that user to re-authenticate until a
specified period passes, which is referred to as Quiet Period. This value functions to protect
the device from malicious attacks. The default value of Quiet Period is set to 5 seconds.
A shorter Quiet Period may speed up re-authentication for users.
In the privileged mode, you can set the Quiet Period through the following steps:
Command
Function
configure terminal
Enter the global configuration mode.
dot1x timeout quiet-period seconds

end
Return to the privileged mode.

You can use the no dot1x timeout quiet-period command to restore the Quiet Period to its
default.In the example below the QuietPeriod value is set to 500 seconds:
DGS-3610# configure terminal
DGS-3610(config)# dot1x timeout quiet-period 500
DGS-3610(config)# end
