On a Cisco IOS switch, run "show interface GigabitEthernet 0/x" where "x" is the number of the port. You should see something like this in the output:

Auto-duplex (Full), 1000Mb/s, media type is SX

Auto-duplex (Full), 1000Mb/s, media type is LX

On a Catalyst OS switch, run "show port x/y" where "x" is the slot the module is in, and "y" is the port where the GBIC is. (Run "show port" to see all ports.) You should see something like this:

Port Name Status Vlan Duplex Speed Type

----- ------------------ ---------- ---------- ------ ----- ------------
