Gentlemen,
I am receiving the following errors on our core switch that I am concerned about. I have read other support posts on this here at Cisco but I still have some questions:
- This is not "normal" broadcast traffic, that my switch is logging correct and is an error that should be followed up on correct? Especially due to the amount of packets I am getting dropped.
- I assume this is a faulty NIC or a mis configured host spewing this traffic and I want to track it down. Any suggestions for tracking down the source as I can't seach mac tables for source of 00:00:00 ..etc
