VTP Pruning

I have VTP pruning enabled and I can see that it should be working, but is there a way to see what vlans are acutely pruned on any give port or switch? Not just what is eligible, but actively pruned.

Thank You

I don't have any switches that have VTP enabled (mainly a Dell switch shop), but you *may* be able to do something like:

sh spanning-tree int g1/2 detail

I gave it a shot, lots of detail, but nothing about pruning.

Thank You

show vtp status doesn't show you what you're wanting?

sh vtp status only shows that pruning is enabled, but not which vlans are being pruned.

"sh interface trunk" will show which vlans are pruned and which aren't ie. from a 3750 switch -

show interface trunk

Port Mode Encapsulation Status Native vlan

Gi1/0/1 auto negotiate trunking 1

Port Vlans allowed on trunk

Gi1/0/1 1-4094

Port Vlans allowed and active in management domain

Gi1/0/1 1-4

Port Vlans in spanning tree forwarding state and not pruned

Gi1/0/1 1-4

Note last entry about vlans in STP forwarding and not pruned.

Another is "show interface switchport". It will give you a more detailed output.
