Guys,
Thanks for testing this on your 3550s.
I think there is a trick somewhere when you want to
change the VTP names. I think it will not let you
change the client VTP name unless if you delete it
first or change the VTP server name first or something
like that. Can someone with 3550s confirm that please?
Thanks again
Loizos
