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.

This chapter describes the Cisco NX-OS interface commands that begin with D.
To set a delay value for an interface, use the delay command. To restore the default delay value, use the no form of this command.
Throughput delay in tens of microseconds. The range is from 1 to 16,777,215. |
Interface configuration mode
Subinterface configuration mode
|
|
This example shows how to set a delay of 30,000 microseconds on an interface:
This example shows how to set a delay of 1000 microseconds on a subinterface:

---|---|
To add a description to an interface configuration, use the description command. To remove the description, use the no form of this command.
String description of the interface configuration. This string is limited to 80 characters. |
Interface configuration mode
Subinterface configuration mode
Virtual Ethernet interface configuration
|
|
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.
This example shows how to add a description for an interface:
This example shows how to add a description for a virtual Ethernet interface:

---|---|
Displays the virtual Ethernet interface configuration information. |

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.
no duplex { full | half | auto }
Specifies the duplex mode as half. Note This keyword is not supported on a management interface. |
|

---|---|
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 example shows how to specify the duplex mode for full duplex:

---|---|
Displays information about the interface, which includes the duplex parameter. |
