Bio

I have worked with Cisco equipment for 20 years. I've designed and supported small to large networks, as well as taught many Cisco courses. (I'm CCSI #94069 and originally certified in 1994). My background is primarily Route and Switch and my interests include security and VPN technology.
Originally, I started reading and posting to network forums as
one mechanism to help me ramp up for my CCIE certification (#4615 which I earned in 1999). Now I use the forums to help keep me sharp in various technical areas as well as to help others. I like contributing, and I find I can answer
a bunch of the questions quickly. For the 'harder' questions,
I personally get a great deal of satisfaction from digging into
topics that I haven't refreshed on for awhile.
I really enjoy working for Chesapeake Netcraftsmen, they are a
great group of fun and smart people (including 10 CCIEs).
We have consulting and training expertise in high-end routing
and design, switching, VoIP, QoS, MPLS, network management,
security, IP multicast, course and lab development, and other
areas.
