Here is the "Book" Answer

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.

You have the port and vlan info in the message. I'd suggest that an interface card is misbehaving.

PO10 is for another switch in my network and yes I have the VLAN on the message but can you help me trace it down to the specific port of the switch.  How would i trace that out?

Thanks.

Well, what ever is on port 10 is your culprit. If its another switch I'd look there.

shah.nowrose Wed, 02/15/2012 - 12:59

Po10 is a port channel to another switch and that switch is a 3750 and it does not show these error messages.  Also that is a stack of 6 48port switches how can I trace it down to one port?  Can't even trace via MAC since its all zero's any other suggestion would be great.


Thank you,

move the port channel to another port and see if it follows.

shah.nowrose Thu, 02/16/2012 - 06:20

I am going to try that out and let you know.  Thank you very much for your help so far really appreciate it.

Try to check the interfaces you include in your portchannel . check if those interfaces have crc errors. if you are using a fiber for your uplink connection, try to replace your fiber  with another working one.

Hope it helps.

Elly.
