In the output, Port is the port as seen on the rear panel. Ports Gi0/25 and Gi0/26 are internal to the switch architecture. Ports Ex0/1 and Ex0/2 are the two SFP+ uplink ports. The Status is the state of the port. The Duplex, Speed, and Negotiation are the parameters of the link. The Capability indicates if auto-crossover capability is on.
