speed-duplex

This command configures the speed and duplex mode of a given interface when auto-negotiation is
disabled. Use the no form to restore the default.

Syntax

speed-duplex {1000full | 100full | 100half | 10full | 10half}

no speed-duplex

1000full - Forces 1000 Mbps full-duplex operation

100full - Forces 100 Mbps full-duplex operation

100half - Forces 100 Mbps half-duplex operation

10full - Forces 10 Mbps full-duplex operation

10half - Forces 10 Mbps half-duplex operation

Default Setting

Auto-negotiation is enabled by default.

When auto-negotiation is disabled, the default speed-duplex setting is 100full on the
1000BASE-T ports.

Command Mode

Interface Configuration (Ethernet, Port Channel)

Command Usage

The 1000BASE-T standard does not support forced mode. Auto-negotiation should always be
used to establish a connection over any 1000BASE-T port or trunk. If not used, the success of
the link process cannot be guaranteed when connecting to other types of switches.

To force operation to the speed and duplex mode specified in a speed-duplex command, use
the

no

negotiation

command to disable auto-negotiation on the selected interface.

When using the

negotiation

command to enable auto-negotiation, the optimal settings will be

determined by the

capabilities

command. To set the speed/duplex mode under

auto-negotiation, the required mode must be specified in the capabilities list for an interface.

Example

The following example configures port 5 to 100 Mbps, half-duplex operation.

Console(config)#interface ethernet 1/5

Console(config-if)#speed-duplex 100half

Console(config-if)#no negotiation

Console(config-if)#
