Chapter 2 Cisco ME 3400 Ethernet Access Switch Cisco IOS Commands
To configure speed or duplex settings on a dual-purpose port, you must first select the media type. If you
configure auto-select, you cannot configure the speed and duplex 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).
When the media type ia auto-select, the switch uses these criteria to select the media type:

An SFP is not installed until it has a fiber or copper cable plugged into the SFP module.
If only one media type is installed, that interface is active and remains active until the media is
removed or the switch is reloaded.
If you install both media types in a dual-purpose port that is enabled, the switch selects the active
link based on which type is installed first.
When the switch powers on with both cables connected, or when you enable a dual-purpose 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 the type that first links up.
