In the new Stackwise MIB with 12.2.25.SEE, there's a StackwiseRingRedundant indicator... on one of my switch pairs, it shows False (2) but both stack ports show Up in the CLI and passing frames in show switch. The only difference is that the other pairs are connected in an X (1-2) and the "non-working" pair is connected 1-1/2-2. Could that be making it show False? I know it works redundantly that way...
Thanks - Al
