media-type
media-type
Use the media-type interface configuration command to manually select the interface and type of a
dual-purpose uplink 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.
media-type {auto-select | rj45 | sfp}
no media-type
Syntax Description
Defaults The default is that the switch dynamically selects auto-select.
Command Modes Interface configuration
Command History
Usage Guidelines You cannot use the dual-purpose uplinks as redundant links.
To configure the speed or duplex settings on a dual-purpose uplink, you must select the interface type.
When you change the type, the speed and duplex configurations are removed. The switch configures both
types with autonegotiation of both speed and duplex (the default).
When you select auto-select, the switch dynamically selects the type that first links up. 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).
When you select rj45, the switch disables the SFP module interface. If you connect a cable to this port,
it cannot attain a link up 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 link up 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.
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.
auto-select Enable the switch to dynamically select the type based on which one first links up.
rj45 Select the RJ-45 interface.
sfp Select the small form-factor pluggable (SFP) module interface.
