The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The description command is meant to provide a reminder in the configuration to describe what certain interfaces are used for. The description appears in the output of the following commands such as show interface and show running-config.
You can use this command on the following interfaces:
This example shows how to add a description for an interface:
switch# configure terminal switch(config)# interface ethernet 1/1 switch(config-if)# description "10G Server Link" switch(config-if)#
This example shows how to add a description for a virtual Ethernet interface:
switch# configure terminal switch(config)# interface vethernet 1 switch(config-if)# description "Virtual interface" switch(config-if)#

Command |
Description |
|---|---|
|
show interface ethernet |
Displays the interface configuration information. |
|
show interface vethernet |
Displays the virtual Ethernet interface configuration information. |
|
show running-config |
Displays the contents of the currently running configuration file. |
To specify the duplex mode as full, half, or autonegotiate, use the duplex command. To return the system to default mode, use the no form of this command.
duplex { full | half | auto }
no duplex { full | half | auto }
|
full |
Specifies the duplex mode as full. |
||
|
half |
Specifies the duplex mode as half.
|
||
|
auto |
Specifies the duplex mode as autonegotiate. |
None

This command was introduced. |
The interface speed that you specify can affect the duplex mode used for an interface, so you should set the speed before setting the duplex mode. If you set the speed for autonegotiation, the duplex mode is automatically set to be autonegotiated. If you specify 10- or 100-Mbps speed, the port is automatically configured to use half-duplex mode, but you can specify full-duplex mode instead. Gigabit Ethernet is full duplex only. You cannot change the duplex mode on Gigabit Ethernet ports or on a 10/100/1000-Mbps port that is set for Gigabit Ethernet.
See the Cisco Nexus 5000 Series NX-OS Layer 2 Switching Configuration Guide for more information on interface speed and duplex settings.
This command does not require a license.
This example shows how to specify the duplex mode for full duplex:
switch# configure terminal switch(config)# interface ethernet 1/5 switch(config-if)# duplex full switch(config-if)#
