Hi John,
I had a look on Univercd, and it said to verify the VTP Pruning you will
need to use:
show vtp status
Here is the link:
http://www.cisco.com/univercd/cc/td/doc/product/lan/c3550/12120ea2/3550scg/swvtp.htm#wp1072526
Wandering off on a little tangent, I learnt something interesting as well.
I always wondered if I needed to manually put the VLANs in the
'pruning-eligible list' on a trunk.
But at this link:
http://www.cisco.com/univercd/cc/td/doc/product/lan/c3550/12120ea2/3550scg/swvlan.htm#wp1221846
It says that 'The default list of VLANs allowed to be pruned contains VLANs
2 to 1001.'
very interesting...
