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.
