Running CW 2.5.1 with latest updates.
CM Topology map is not being populated from RME groups. On some 3750 stacks it shows correctly linked edge switches, but on others it shows nothing. Using Device Manager, some 3750 stacks show cdp neighbours, others show none (even though you can see cdp neighbours at the cmd line).
Same batch of 3750's, same IOS, identical configs.
Have deleted a 3750 from RME, rebooted CW, then re-added it & still get the same problem. Has anyone else seen this or have any ideas on why??
