Good afternoon,

what will be a cause of the stacking port to failed, only one port of the node is down , stacking ring still up connectivity remains on the node, any commands to see what causes the error? just reboot the node?

thanks

Is the failed port in NP mode?

Choose a time when the stack can be down. Take one switch out of the stack ("disable stacking node address xx:xx:xx:xx:xx:xx") which will reboot into factory default mode. Loop the stacking cable, then run stack port diagnostics ("run diagnostics stack-port"). After that completes, I would run regular diagnostics as well ("run diagnostics normal"). Reconnect the cable into the ring and put it back into the stack ("enable stacking node address xx:xx:xx:xx:xx:xx") . Keep track of stack member mac addresses to simplify the process. Repeat the process on all stack members and all cables. Hopefully it will tell you something useful.
