media-type

Use the media-type interface configuration command to manually select the interface and type of a

dual-purpose port or to enable the switch to dynamically select the type that first links up. Use the no

form of this command to return to the default setting.

This command is visible only on the Cisco ME- 3400G-12CS and ME-3400G-2CS switches.

Syntax Description

The default is that the switch dynamically selects the link (auto-select)

Usage Guidelines

You cannot use the RJ-45 interface and the SFP interface of the dual-purpose ports simultaneously to

provide redundant links.

When you select auto-select, the switch dynamically selects the type that first links up. This is the

default mode. The switch disables the other media type until the active link goes down. When the active

link goes down, the switch enables both types until one of them links up. If there are active links on both

media, the SFP link has priority. In auto-select mode, the switch configures both types with

autonegotiation of speed and duplex (the default).

When you select rj45, the switch disables the SFP module interface. If you connect a cable to the SFP

port, it cannot attain a linkup 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.

When you select sfp, the switch disables the RJ-45 interface. If you connect a cable to this port, it cannot

attain a linkup 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.
