Hello,
Has anyone had these same symptoms on software version 16.3.7?
I had a switch stack reboot and now one of the stack ports is un-useable.
-I tried replacing the stack module as well as the stacking cable however the switch would still show Stack port 1 on switch 1 failed to authenticate during the boot and then just stay there. Mean while the switch member 2 booted completely leaving half of a production line not working.
Please let me know if anyone else has seen this issue using WS-C3650-48FQM-S switches on software version 16.3.7
Thanks
