Hi everyone,
I think is an easy question but I have a doubt about it, I hope someone can help me. I need Know what connection is using on Cisco 2811 router.
I have this interface in Cisco 2811, I need Know if this port is connected to Fiber or Copper. I think is copper with RJ45 but I see 100 base TX/FX so this make me doubt about it because TX its for copper link and FX for fiber.

Please read again what I wrote. Fa0/0 is fixed 100Base-TX.
This is the out for show inventory raw command:
"For ports other than fa0/0 and 0/1..."
show interface fast 0/0 capabilities is not allowed.
"By the way, on switches..."; that was just an extra info.

Hi,
Please let us know whether you have this interface supoorting both SFP and RJ-45..?
If yes this may be due to dual support on this interface but at a time you can use only 1.
Thanks

How can I do it?

FastEthernet0/0 is the first fixed port on the 2811, it's 100Base-TX. For ports other than fa0/0 and 0/1, check the HW by entering the show inventory command.
By the way, on switches you can get the required information by entering the show interfaces capabilities or the show interfaces

This is the out for show inventory raw command:
