Command Usage

The description is displayed by the show interfaces status command
(page 4-229) and in the running-configuration file. An example of the value
which a network manager might store in this object is the name of the
manufacturer, and the product name.

Example

The following example adds a description to port 24.

speed-duplex

This command configures the speed and duplex mode of a given interface when
autonegotiation 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 for both

100BASE-TX and Gigabit Ethernet ports is 100full.

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. However, this switch does
provide a means of safely forcing a link to operate at 1000 Mbps, full-duplex
using the giga-phy-mode command (page 4-225).

• 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
