Description (partial)


On a Catalyst 4500 switch running 12.2(50)SG or 12.2(52)SG, when 802.1x is enabled on a port, ARP snoop is always activated on the port even if device tracking table is not globally enabled on the switch. The problem may have a small performance impact due to the unnecessary ARP snoop.


Without device tracking table globally configured on the switch, ARP snoop should not be active solely due to 802.1x enabled on the port.
