What issue?
All I can see are alarms for power supply 1.

[Richard Burts · Accepted solution]

There are quite a few messages like this one

000196: *May 14 10:02:27.507: %C4K_L2MAN-6-INVALIDSOURCEADDRESSPACKET: (Suppressed 1 times)Packet received with invalid source MAC address (00:00:00:00:00:00) on port Te1/2 in vlan 132

I am interested in the fact that some of these messages show Re1/2 to be in vlan 130, while others show it to be in vlan 132, and still other show it to be in vlan 136. What can you tell us about Te1/2? How is it configured? What is connected to it?

[Richard Burts]

Thank you for showing us the configuration. Can you tell us what is connected on this interface? It might also be helpful if you would post the output of the command show interface trunk.

Hi!

You are having two problems:

1) One of your Power Supplies is etiher faulty or it's power source is flapping.

2) Endpoints connected via Te1/2 are sending frames with invalid source MAC (either all 0 or a Multicast MAC).

Could you share the output of the following?

#show run int Te 1/2

Thanks

Juls
