The switch received a packet with the MAC address 00:00:00:00:00:00. This MAC
Explanation
address is not valid and was probably generated by some non-IEEE 802.1D-compliant hardware or
software in the network.
The host sort algorithm does not sort hosts with MAC addresses that have all zeros
(00:00:00:00:00:00), because a MAC address that has all zeros can not be listed in the learned host
table. A request to show learned hosts, either by the show cam dynamic command or by an SNMP
request, does not list a MAC address that has all zeros.
Track the source of the invalid MAC address because it might cause other

problems.
The system could not obtain the memory it needed or the operation was not allowed.

redundancy mode.
Recommended Action Switch to RPR mode or use an SVI in a VLAN where a layer 2 port channel is
the only member.
The Port Aggregation Protocol or EtherChannel cannot obtain the memory it needs.
