Good day,

I have been seeing multiple port security violation on my switch (c7609) to the point that am hardly able to see anything else.  When I investigated the port security at the time that the violation errors are appearing the total mac addresses are way less than the maximum configured for the port. Could someone assist me with this .

Sep  4 14:23:26.160 EST: %PORT_SECURITY-SP-2-PSECURE_VIOLATION: Security violation occurred, caused by MAC address f4dc.f9db.0c2a on port FastEthernet3/11.
