How can i request rx (and tx) errors on extreme (alternate) stacking port - escpecially 10Gb / 40GB ports. Standard "show port rxerrors" will not work because ports are in the Stacking mode and in currently indicated as NP (not present). "Show stacking stack-ports" does also not provide this information.
How can i determine if maybe some cable or gbic problem exists on the stacking connections.
