I recently discovered my controllers thought they were the root bridge, and it appeared to be due to them using rapid-stp. I changed this over and afterward found that I receive no output from issuing show spanning-tree. Another thread indicated a similar problem and a suggestion to try show spantree was given. This too seems to give no output.
I would like to enable spanning-tree on the controllers so that they can participate in the layer 2 broadcast domain like all other switches we run. The goal is to use one 10g port and one 1g port, so that if the 10g fails it will have a 1g alternate state blocking port to use immediately rather than failover completely to the secondary in our HA pair.
Is there any way to verify the local spanning-tree configuration once you have migrated to rapid-pvst?
