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.

delay tens-of-microseconds

no delay

Syntax Description Throughput delay in tens of microseconds. The range

is from 1 to 16,777,215.

tens-of-microseconds

Command Default 10 microseconds

Command Modes Interface configuration mode

Subinterface configuration mode

Command History ModificationRelease

This command was introduced.4.0(0)N1(1a)

Support for Layer 3 interfaces was added.5.0(3)N1(1)

Examples This example shows how to set a delay of 30,000 microseconds on an interface:

switch(config)# interface ethernet 1/1

switch(config-if)# delay 30000

switch(config-if)#

This example shows how to set a delay of 1000 microseconds on a subinterface:

switch(config)# interface ethernet 1/1.1

switch(config-subif)# delay 1000

switch(config-subif)#

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.

You can use this command on the following interfaces:

•Ethernet interface

•Management interface

•Subinterfaces

•Virtual Ethernet interface

D Commands

description (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.

duplex {full| half| auto}

no duplex {full| half| auto}

Syntax Description Specifies the duplex mode as full.full

Specifies the duplex mode as half.

This keyword is not supported on a

management interface.

Note

half

Specifies the duplex mode as autonegotiate.auto

Command Default None

Command Modes Interface configuration mode

network-adminvdc-admin

Command History ModificationRelease

This command was introduced.5.1(3)N1(1)

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.

This command does not require a license.

Examples This example shows how to specify the duplex mode for full duplex:

switch#

configure

terminal switch(config)#
