Could someone assist me with this . Was the MAC address recently seen on another port? The aging time may be set too high for hosts that are changing ports more rapidly. It may also be that the MAC address is already present on another port, doing just what port security was largely designed to do. This may be a true violation or in many cases I've seen there was a bridge loop, you may also be getting loop messages if that is the case.
