Spanning Tree is blocking one of the ports on one of my Aruba J9773A switches.
How do I discover what port on what device is on the other end of the cable connected to that port?
It's probably one of many other Aruba switches in that location, I would like to know precisely which one.
What I've tried:
- List LLDP neighbours/remote-devices on that port: None.
- View the MAC address learned on that port: None.
- Looked over the spanning tree debug information, and other spanning tree logs: Didn't include what I'm looking for.
Is tracing the physical cable the only way to figure this out?
