I had a 2611 hooked up to my 5500 the other day with port security turned
on. It worked fine for about 6 hours, then all of the sudden the switch
shut the port down due to a security error. I looked, and the switch was
reporting that a totally different mac address was plugged into that port.
I looked at the 2611 and it was fine, same mac address that was in the port
security filter. Has anyone seen this before? If turning on port security,
is it a good idea to lock the mac address down to something other than the
bia? Thanks.
