I've seen VTP fail spectacularly. A customer was using it on about 30 switches distributed to about 10-15 wiring closets. They had a temp student come in who wanted to learn about networking, so the student copied the core switch configuration and deployed it on a lab switch. The student decided to wipe the VLANs from this lab switch and start from scratch.
When the lab switch was connected to the production network, its VTP instance had the correct VTP password (as it was copied from the core switch), but it had none of the VLANs required for the correct operation of the network, and of course it had the higher revision number. It was an innocent mistake, but it ended up to be a very bad day for everyone involved and we've never used VTP for any other customer since that day. --- Paul Wozney Network Consultant phone: +1 604-629-9975 toll free: +1 866-748-0516 email: [email protected] web: http://wozney.ca On Wed, Feb 9, 2011 at 14:10, Martin Barry <[email protected]> wrote: > $quoted_author = "Nick Hilliard" ; > > > > Also, don't use VTP unless you like living dangerously. > > Nick, that sounds like you have a good war story or three.
