Hi,I meet this problem several days ago, and i still have no idea to deal with this problem.Can someone help me? Thanks.

I have a Cisco WS-C3750X-48P-S switch and want to figure which port is fiber sfp and which port is copper sfp.

Gi1/0/5 connected trunk a-full a-1000 unsupported
Gi1/0/9 connected trunk a-full a-1000 1000BaseSX SFP
Gi1/0/11 connected 1 a-full a-1000 10/100/1000BaseTX SFP

Is gig1/0/9-gig1/0/11 a copper sfp transceive ?

One of them is copper, other is Multimode FO.

Most common SFP standards are:
SX - multimode FO
TX - copper
LX - singlemode (1310nm wavelength) FO
ZX - singlemode (1550nm wavelength) FO

See http://en.wikipedia.org/wiki/Gigabit_Ethernet for more details.
