Sniffer Cert?

["Sheahan, John" <John.Sheahan () priceline com>]

Not that I am interesting in chasing certs but I do remember when I studied for the old CNX cert many years ago which 
was very helpful and allowed me to get an in depth knowledge of troubleshooting with a sniffer.

Is there anything similar to this that might be good to expand my knowledge base?

thanks
