Error Message C4K_L2MAN-6-INVALIDSOURCEADDRESSPACKET:Packet

received with invalid source MAC address ( [mac-addr] ) on port

[char] in vlan [dec]

Explanation A packet was received with an all zero or a multicast source address. The packet is treated as invalid and no learning is done. Excessive flow of such packets can waste CPU cycles. This message is rate-limited and is displayed only for the first such packet received on any interface or VLAN. Subsequent messages will display cumulative count of all such packets received in given interval on all interfaces.

Recommended Action Check the switch configuration file to find the source of these packets on the specified port and take corrective action to fix them at the source end. You can also enable port security on that interface to shutdown the port if the incoming rate of packets with invalid source mac address is too high by issuing the

switchport port-security limit rate invalid-source-mac command.
