Hi,
Is anybody else seeing 3750 PoE switches coming on to your maps, but missing links between neighbouring 3750 switches. We are upgrading from 3500XLs, which all showed links without failure, to 3750s stacks.
The topology is core switch 1 <-> access 3750 cluster closet A switch <-> access 3750 cluster closet B <-> core switch 2 in a redundant configuration.
snmp is fine from the Ciscoworks host, and cdp on the switches shows both uplinks back to each side of the core layer.
ios is 12.2.20

Do you have Spanning tree protocol disabled ?

We are running mst stp on all the switches.
