list is currently down (but not considered dead). Now, if the supplicant retransmits EAPOL Start
frames at a rate faster than X seconds, then it will never get authenticated, because the switch will
cancel on-going backend authentication server requests whenever it receives a new EAPOL Start
frame from the supplicant. And since the server hasn’t yet failed (because the X seconds haven’t
expired), the same server will be contacted upon the next backend authentication server request
from the switch. This scenario will loop forever. Therefore, the server timeout should be smaller
than the supplicant’s EAPOL Start frame retransmission rate.
