Switch Port Commands

108-1 duplex
This command is used to configure the physical port interface's duplex setting. Use the no form of
command to revert to the default setting.
duplex {full | half | auto} [rj45 | sfp]
no duplex [rj45 | sfp]
Parameters
full
half
auto
rj45
sfp
Default
The duplex mode will be set as automatic for 1000BASE-T interfaces.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
For 1000BASE-T modules, if the speed is set to 1000, then the duplex mode cannot be set to half-duplex.
If the duplex mode is set to half-duplex, then the speed cannot be set to 1000.
Auto-negotiation will be enabled if either the speed parameter is set to auto or the duplex parameter is set
to auto if the speed parameter is set to auto and the duplex parameter is set to the fixed mode only the
speed will be negotiated. The advertised capability will be configured to the duplex mode combined with
all the possible speeds. If the speed is to set to a fixed speed and duplex is set to auto, only the duplex
mode is negotiated. The advertised capability will be both full and half-duplex mode combined with the
configured speeds.
Example
This example shows how to configure the interface Ethernet 1/1/1 to operate at a forced speed of
100Mbits and specifies that the duplex mode should be set to auto-negotiated.
Switch# configure terminal
Switch(config)# interface ethernet 1/1/1
Switch(config-if)# speed 100
Switch(config-if)# duplex auto
Switch(config-if)#
Specifies that the port operates in the full-duplex mode.
Specifies that the port operates in the half-duplex mode.
Specifies that the port's duplex mode will be determined by auto-
negotiation.
(Optional) Specifies to configure the duplex for RJ45 media. For
combo ports, if RJ45 or SFP is not specified, RJ45 is implied.
(Optional) Specifies to configure the duplex for SFP media.
