No Spanning-Tree Vlan # on C2950

Hello everyone,

I've recently found that one of the switches on my network (which I never set up) is running a "no spanning-tree vlan 3, 5, 10" command, which I want to remove, but I have been unable to. When I do try and type in "spanning-tree vlan 3" nothing comes up, but when I show spanning tree it lets me know that it doesn't exist.

Is there a command I'm missing? (It's a larger number of vlans)

Thanks in advance,
David

Does vlan 3 exist on the

Does vlan 3 exist on the switch and are any ports assigned to vlan 3?

It does exist in the vlan

It does exist in the vlan table, it's coming from VTP. No ports are designated specifically with VLAN3

I'm not sure there would be

I'm not sure there would be anything for spanning tree to calculate if no ports on the switch are assigned to vlan 3.  Try assigning an unused port to vlan 3 and see if your output of sh spanning-tree vlan 3 changes.
