Just in case there are any Cisco certified engineers here...
I'm trying to help debug a network issue:
Running a Cisco Catalyst 6509 with IOS software. After a lot of hassle, finally managed to get CiscoView 6 installed and running (as part of Ciscoworks) in order to try and fault find an issue we have where a networked system stops functioning.
Looking at the status of the Supervisor engine (it's a Sup720), I get a shed load of UDP errors, just about as many errors as UDP packets sent over the network
I've set up a span monitoring port on the cisco and have ethereal running on a host PC capturing all network traffic, but as you can imagine, there's a fair few million packets whizzing around the place and I don't know where to start
However, if someone was able to technically explain what is meant by a "UDP error", i.e. what does a UDP packet need to have / not have for it to be considered erroneous
That way, it might help me narrow down and find the cause of the issue.
TIA
