Hello,
one of my sensors is listening to traffic using the SPAN feature on a switch, and this is probably causing trouble on the switch. Is there any history of trouble with the spwr interface, or could it just be that the spanning is not set up correctly.
The switch in question is a Catalyst 3524 running IOS 12.0(5.2)xu and the error message goes something like addr_flap [interface] relearning [x] addresses per minute.
Any clues?
