I am attempting to use Wire Shark to track a Jumbo Frame issue that I am seeing on my network. I do not have Jumbo Frames enabled on any device on my network but I am continuously getting Jumbo Frames (which show up as errors on one of my switch stacks) and I have no idea where they are coming from. I have connected the PC that I have Wire Shark on to the receiving switch stack but the switch is dropping the jumbo packets as errors so I do not see them. I have connected the PC to the switch stack that the packets would be the sending switch stack and I still have no idea where these packets are coming from. Any advice? Specific configuration on Wire Shark that would help capture it? asked 05 Dec '16, 13:41  cerobinson |
One Answer:
You will need to get serious with the network devices detailed statistics, which I assume you already are, too see where the jumbo frame counters add up. Otherwise a network tap to insert into the network link and a beefy capture platform to get the traffic on that fiber link and see what it tells you. answered 12 Dec '16, 08:38  Jaap ♦ |
