Spanning Tree Mapping Ports

We have just had a big spanning tree loop between our two core switches, we are about to enable Spanning Tree Portfast BPDU Guard Enhancement but want to map the current port states. What is the best way to do this, to see which ports are root, designated and blocking?

Re: Spanning Tree Mapping Ports

From the switch, show spanning tree will tell you what your root swith and port is.
