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

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)#
