I have noticed that two of my switches has "spanning-tree vlan 1002-1005" in my running configuration. Since we are not using those vlans, I was thinking of removing it from our running configuration by doing "no spanning-tree vlan 1002-1005". Is that possible? Would there be any issues should I remove it?
VLANs 1002-1005 are special default VLANs for Token Ring and FDDI. If you do not have those tachnologies, then you are probably not using those VLANs. Do the VLANs exist in the VTPS domain? If not, you should be able to get rid of them altogether.
When you do a "show vlan 1002" on those switches, do you see any active ports? NOte that some switches allow you to clear these VLANs from a trunk, and some do not.
