To return to the default setting, use the media-type auto interface or the no media-type interface
configuration commands.
When you change the interface type, the speed and duplex configurations are removed. The switch
configures both types to autonegotiate speed and duplex (the default). If you configure auto-select, you
cannot configure the speed and duplex interface configuration commands.
When the switch powers on or when you enable a dual-purpose uplink port through the shutdown and
the no shutdown interface configuration commands, the switch gives preference to the SFP module
interface. In all other situations, the switch selects the active link based on which type first links up.

Purpose
Select the interface and type of a dual-purpose uplink port. The
keywords have these meanings:
•
auto-select—The switch dynamically selects the type. When link
up is achieved, the switch disables the other type until the active
link goes down. When the active link goes down, the switch
enables both types until one of them links up. In auto-select
mode, the switch configures both types with autonegotiation of
speed and duplex (the default). Depending on the type of installed
SFP module, the switch might not be able to dynamically select
it. For more information, see the information that follows this
procedure.
rj45—The switch disables the SFP module interface. If you
•
connect an SFP module to this port, it cannot attain a link even if
the RJ-45 side is down or is not connected. In this mode, the
dual-purpose port behaves like a 10/100/1000BASE-TX
interface. You can configure the speed and duplex settings
consistent with this interface type.
sfp—The switch disables the RJ-45 interface. If you connect a
•
cable to the RJ-45 port, it cannot attain a link even if the SFP
module side is down or if the SFP module is not present. Based
on the type of installed SFP module, you can configure the speed
and duplex settings consistent with this interface type.
For information about setting the speed and duplex, see the
and Duplex Configuration Guidelines" section on page
Return to privileged EXEC mode.
Verify your setting.
(Optional) Save your entries in the configuration file.
