Hi
We have come accross multiple messages:
%C4K_L2MAN-6-INVALIDSOURCEADDRESSPACKET: (Suppressed 2608 times)Packet received with invalid source MAC address (00:00:00:00:00:00) on port Gi4/11 in vlan 135
and
%PORT_SECURITY-2-PSECURE_VIOLATION: Security violation occurred, caused by MAC address 0000.0000.0000 on port GigabitEthernet4/35
These are happening really random here and the and early hours of the morning when the company is closed which might be a printer.
Can the follwoing mac-access list be applied on per interface basis on incoming traffic these would exclude trunks.
mac access-list extended AllZeroMacs
deny host 0000.0000.0000 any
permit any any
Thoughts and suggestions welcome.
