What is cucsEtherPIoPeerDn?

This is peerDn, the Dn of the device or port directly connected to the far end of this specific physical port, discovered via link-layer neighbor discovery. It tells you exactly what is plugged into this port without having to physically trace a cable through a dense data-center rack. For example, peerDn identifying a specific IOM uplink confirms this FI port is cabled to chassis 2's IOM-A rather than IOM-B, catching a miscabled uplink before it causes a surprise during a fabric failover.

Examples
