How are the ports labeled on a Cisco WS-C2960G-48TC-L

WS-C2960G-48TC-L： 44 10/100/1000 and 4 dual-purpose uplinks, has two or four dual purpose ports that are a combination of an RJ45 copper and an SFP slot. In the CLI when I do a show interface status I get 48 ports. Gi0/1-44 show as 10/100/1000baseTX but Gi0/45-48 show as auto not present.

How does this work?

Do the dual purpose ports de-activate port Gi0/45-48 when they are used?

Below is the solution:

It is a dual purpose port, so you able to use it 10/100/1000 copper or you able to plug SFP to use optical connections!

so you have GigabitEthernet ports 0/1 to 0/44 copper

and you have GigabitEthernet 0/45 to 0/48 dual purpose ports....

it shows no sfp detected....:

Gi0/2  notconnect  1    auto  auto Not Present

it shows sfp detected....:

Gi0/1  40 es szoba     connected   trunk  a-full a-1000 1000BaseSX SFP
