Hmm, certainly a trunking problem I would say, might want to check that both
trunk ports (the 5500 and 3548) are not set to auto as they will never trunk
(and auto is the Cisco default). You should set the trunk port on the 5500
to desirable. BUT, I think this is the problem....YOU GOT LUCKY! I think
that you probably initially set all the VTP AND VLAN information on the 3548
didn't you? It doesn't matter that the switch was set to VTP client. If
the VTP domain configuration revision is set higher on the 3548 then on the
5500 that you plugged it into then the 5500's are pulling their VTP and VLAN
info from the 3548. That is to say that if you had not configured the
VLAN's on the 3548 prior to trunking it to the 5500 then your entire network
would have gone down as the VLAN configs on all the other switches would
have taken their config from the new "client". Well, I would first check to
see that the revision is indeed greater on the new switch than on your VTP
server (use the show vtp domain command) If it is greater, then I would
reset the revision by changing he domain name on the new switch to some
dummy domain...like set vtp domain reset then change it back to the correct
domain. This reset's the revision back to 0 and everything should start
working properly. Well, it may just be a shot in the dark, but I think one
of the above two items is the issue.
