I just tried with CAPSMAN 2 and ROS v6.44 - if you do so, there is "unsupported channel" message" with CAPSMAN 2.
I know it's an old thread, just I could not find solution elsewhere.
Well, that's not clear. According to Wiki the spanning tree protocol applies to CSR models, which is not my case. Are you saying every router would get that change?Did you read the release notes? Noticed anything about spanning tree? Did you try to disable spanning tree on the bridge?
