I just bough a couple of Cisco 3900 series routers and I see that it has 3 gig ports. But for gig0/1 and 0/2, I see that it is either copper or fiber. I have 2 SX transceivers plug into it. My question is I can use those 2 ports either copper or fiber. Correct? Can I use one with fiber and the other one for copper?
Also, is there a command to see the hardware connection to the ports. On the switch, I use sh int status and I can see the spec for the ports, either copper or fiber. But that command does not seem to work on the router. Thanks
