Can this cause dot1x authentication failure. When I put dot1x on my switch i get the same ports that authenticate initially but within 25 hours they fail authentication. When I remove dot1x I get continuous "LINK-3-UPDOWN & LINEPROTO-5-UPDOWN" on the same ports. The devices are Cisco compatible.
Can flapping cause authentication failure ? If it does why ?
