[nsp] Who's in my VTP domain

[Pete Kruckenberg]

Another unrelated question on the VTP topic.

I had a rather nasty outage today when I discovered that 
some switches are in my VTP domain, acting as servers, that 
I was not aware of.

Is there any way to determine what VTP servers and VTP 
clients are in a given domain?

Short of blocking VLAN 1 on a trunk, is there any other way
(such as disabling VTP on the trunk) to block VTP
traffic--can I run VLAN 1 between two switches, but restrict
VTP traffic from traversing the trunk?

Thanks again.

Pete.
