Anyone have links to Spanningtree commands for a 3508 switch?The commands used on the 2948, 4000 & 5000 series don't work on the 3508!(i.e. "set spantree backbonefast enable" , etc. doesn't work)

Well, actually, I set up a test environment: By running "Uplinkfast" on the Closet switches, both the port to the Router, and the East/West link are Forwarding. But by allowing only the 2 "floor" VLANs on the trunks, The East/West link only passes ...
What are you running on the Router (ip routing only? IRB? )What happens when you do "show ip route" on router? Can a device on vlan 2 ping device on vlan3?
