Setting the Type of a Dual-Purpose Uplink Port
Only Catalyst 2960 switches have dual-purpose uplinks ports.
Note
Some switches support dual-purpose uplink ports. By default, the switch dynamically selects the
interface type that first links up. However, you can use the media-type interface configuration command
to manually select the RJ-45 connector or the SFP module connector. For more information, see the
"Dual-Purpose Uplink Ports" section on page
Beginning in privileged EXEC mode, follow these steps to select which dual-purpose uplink to activate so
that you can set the speed and duplex. This procedure is optional.

The switch might not support a pre-standard powered
device—such as Cisco IP phones and access points that do
not fully support IEEE 802.3af—if that powered device is
connected to the switch through a crossover cable. This is
regardless of whether auto-MIDX is enabled on the switch
port.
