Pcm topology discovery and spanning tree

[blk]

Hi there, another question on pcm, on network map i can watch some spanning tree links between some 5300xl and 4100 switchs but not link between 930x switchs. With sh cdp n command i can see all switch but no 930x , cdp and fdp run on 930x.

I think currently PCM map only supports the single instance spanning tree (STP). For the topology, you'll need to do sh cdp n command on the 930x to show all the connections since the 930x can only listen to CDP packets. If you do sh cdp n command on the 5300 or 4100, you won't see the 930x device since the 930x can not transmit CDP packet because of legal issue.
