D Commands
This chapter describes the Cisco NX-OS interface commands that begin with D.
delay (interface)
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.
Syntax Description
Throughput delay in tens of microseconds. The range is from 1 to 16,777,215. |
Command Default
Command Modes
Interface configuration mode
Subinterface configuration mode
Command History
|

Examples
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:

description (interface)
To add a description to an interface configuration, use the description command. To remove the description, use the no form of this command.
Syntax Description
String description of the interface configuration. This string is limited to 80 characters. |
Command Default
Command Modes
Interface configuration mode
Subinterface configuration mode
Virtual Ethernet interface configuration
Command History

Usage Guidelines
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.
Examples
This example shows how to add a description for an interface:

duplex
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.

Usage Guidelines
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.
Examples
