I have a Cisco Catalyst 3560-CG that has two combo ports with SFP and RJ45 each. Is it possible to manually set the combo port to use the RJ45 only? If so, how is it done? I am troubleshooting a connection and I don't want this to be a variable.
It is the media-type interface command:
The 3560 uses the physical port that can get a link and deactivates the other as long as the link is up. When both variants can get a link (at power on) the SFP port is prioritized.
You can disable the SFP priority with the interface media-type command.
