CLI Reference Guide
Use this command to configure the physical port interface speed/duplex setting.
Specifies to operate in full duplex mode.
Specifies to operate in half duplex mode.
Specifies that the duplex mode will be determined by auto-negotiation.

Interface configuration
Physical port interfaces are valid for this configuration. If the duplex mode is not
supported by the hardware, an error message will be returned.
The following hardware restrictions apply:
• 1000SX/LX is always fixed to 1000 and full duplex.
• 100FX is always fixed 100 and full duplex.
• For all SFP/XFP modules,the duplex command will not take any effect.
Auto-negotiation is enabled if either for speed or duplex. If speed is set to auto,
and duplex is set to full or half mode, then only the speed will be negotiated. The
advertised capability will be the configured duplex mode combined with all
possible speeds. If speed is to set to a fixed speed and duplex is set to auto, then
only duplex mode is negotiated. The advertised capability will be both full and
half duplex mode combined with the configured speeds.
Before adding ports to a Port-Channel, please verify that all settings are identical
on the candidate ports; otherwise the port members of a Port-Channel with
different settings will operate in an indeterminate manner.
This example shows how to configure interface eth3.1 to force the settings to a
speed of 100Mbits and auto-negotiate to the duplex mode.
Verify the settings by entering the show interface command.
