Vmware mac address is all zeros drivers#
I would suggest to investigate whats is connected to this port, check NIC ,application or drivers and update them accordingly. As per our knowledge base most common reason when all zero MAC addresses are generated are PCs running Win 7 going to hibernate more and inactive VMWare machines. Logging messages point to problem on devices sending the frames to the switch, NIC that created the frame encapsulated it with Source MAC filed 00:00:00:00:00:00 which is treated as invalid by the switch. 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.Ġ17474: Aug 14 13:17:19.193 IST: %C4K_L2MAN-6-INVALIDSOURCEADDRESSPACKET: (Suppressed 145 times)Packet received with invalid source MAC address (00:00:00:00:00:00) on port Gi3/1 in vlan 51 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. Subsequent messages will display cumulative count of all such packets received in given interval on all interfaces. This message is rate-limited and is displayed only for the first such packet received on any interface or VLAN. Excessive flow of such packets can waste CPU cycles. The packet is treated as invalid and no learning is done. %C4K_L2MAN-6-INVALIDSOURCEADDRESSPACKET: Packet received with invalid source MAC address ( ) on port in vlan Ī packet was received with an all zero or a multicast source address.
