I hope I'm posting this to the correct area, please do let me know if this post would be more appropriate in another area.
We have deployed 3560s with IOS ver 12.2 <25> sec. in our distribution closets and have engaged port security on all of them. We have port security configured to sticky the MACs and to shut down the ports in the event of a violation.
I have three separate incidences, on three separate switches, where three different printers of different manufacturers are intermittently triggering port security.
We're %100 sure that we do not have a case of someone trying to connect an unauthorized device to the port, and the problem occurs at different times of the day.
There are times when the port will error down several times over the course of an hour, and then again we may go a couple of weeks without incident.
I had enabled logging on the switches, but there wasn't any useful information within the logs. They simple indicate that the port went down.
Anyone have a clue as to what may be causing these printers to trigger port security?
Regards to all
