This value, in seconds, sets the quietPeriod timer used by the 802.1X Authenticator PAE state machine on the switch. After a failed authentication attempt, the switch waits this long before it will process another 802.1X request from the same port, which controls how quickly a rejected client can retry. Left at its default of 60, a supplicant that fails EAP authentication must wait a full minute before the port re-engages; an admin troubleshooting slow reconnects might lower it to 10 seconds during testing.
