I did the show interfaces status command on my 3750-12S-S and I got half of my port as UNSUPPORTED and half 10/100/1000BaseTX SFP (see below)
Port Name Status Vlan Duplex Speed Type
Gi1/0/1 connected trunk a-full a-1000 unsupported
Gi1/0/9 connected 1 a-full a-1000 10/100/1000BaseTX SFP
port 1-6 has fiber connection and 7-12 has cat5E connected.
Why does it say UNSUPPORTED for the fiber?
Is 10/100/1000BaseTX SFP the SFP for copper connection?
