69. Switch Port Commands

69-1 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}
no duplex
Parameters
full
half
auto
Default
The duplex mode will be set as auto 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 eth1/0/1 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 eth1/0/1
Switch(config-if)# speed 100
Switch(config-if)# duplex auto
Switch(config-if)#
69-2 flowcontrol
This command is used to configure the flow control capability of the port interface. Use the no form of
command to revert to the default setting.
flowcontrol {on | off}
no flowcontrol
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.
