Command Usage
The description is displayed by the
show interfaces status
command
(page 4-230) 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.

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 4-226).
• 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
