This is a simple question. I have 4948 switch but I don't know if I have any ports availabe to add an SFP module or whether they are all copper ethernet ports. How can I check what kind of ports are available as I don't have physical access to the switch.

Here's some info:

NAME: "Switch System", DESCR: "Cisco Systems, Inc. WS-C4948 1 slot switch "

PID: , VID: , SN:

NAME: "Linecard(slot 1)", DESCR: "10/100/1000BaseT (RJ45), 1000BaseX (SFP) Supervisor with 48 10/100/1000BASE-T p"

PID: WS-C4948 , VID: V06,

One other suggestion I would have would be to perform the "show interface status" command to determine if the ports in question are in use/active/or have any SFPs plugged in.

See reference from a 3750.

Port Name Status Vlan Duplex Speed Type

Fa0/48 notconnect 1 auto auto 10/100BaseTX

Gi0/1 notconnect 1 auto auto Not Present

Hope this helps, rate if it does.
