Thanks all, in trying to come up with a base level rule when approaching the
switching section I am gonna try the following 3 step rule.
1. If switches are client/server and in same VTP domain then set up trunking
(in fact set up trunking on all switches first), then vtp, then add in vlans
on the server (write vlans into notepad and copy in to server), check they
have propogated to clients.This gets my vlans propogated and tests
vtp/trunking. If not propogating then their may a transparent switch in the
switching path, move to step 2.
2. Add in vlans (from notepad) to transparent switches, they may or may not
be needed on the transparent switch but they may be in the switching path
from a server to a client therefore needed for spanning tree instance. If
there was a transarent switch in the switching path between a client and a
server then check vlans are now propogating.
3. Add in specific "local" vlans on the transparent switch only.
With 4 switches there can be a lot of sceanrios with the vtp modes, Im sure
this base rule will adapt but its a start.
Thanks
