I checked out your suggestions and they were a big help. Both Sniffer and OmniPeek have no prices listed – they want you to call them for prices. This likely means they are in the thousands of dollars and need a sales rep to talk you into purchasing. So they are out of my budget. However, there were some useful whitepapers at the Netscout Sniffer site.

A managed switch with a laptop might be a solution but not as portable as I would like.

I liked Wireshark – mainly because there seems to be some high quality training offered by Laura Chappell. An app isn’t much good unless you know how to use it and the training, though expensive, seems well presented. Additionally, the training would be less money than purchasing either Sniffer or OmniPeek.

Thanks so much for the help.
