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.

You can check rxerror/txerror in stacking ports by command

sh port stack-ports txerrors|rxerrors

Is it possible to get an alarm (syslog or trap) if command "show port stack-ports rxerrors" shows any errors ?

Maybe via CLEAR Flow / UPM / EXOS Scripting ?

Unfortunately this values are NOT able to monitor via SNMP!

i opened a GTAC Case for this - now i have a feedback!

Unfortunately there is no EMS Event to trigger an event NOR you can read out this values via SNMP!
So i create a Feature Request to have this (maybe) in the near future.
