Configuring Port Settings
Beginning in Privileged EXEC mode, use the following commands to
configure various port settings.
Command Purpose
configure Enter Global Configuration mode.
interface
interface Enter interface configuration mode for the specified
interface. The interface variable includes the interface type
and number, for example tengigabitethernet 1/0/3.
A range of interfaces can be specified using the interface
range command. For example, interface range
tengigabitethernet 1/0/8-12 configures interfaces 8, 9, 10,
11, and 12.
description
string Add a description to the port. The text string can be
from1-64 characters.
shutdown Administratively disable the interface.
speed {10
|100|1000|10000 | auto
[100|1000|10000]}
Configure the speed of a given Ethernet interface or allow
the interface to automatically detect the speed.
If you use the 100, 1000, or 10000 keywords with the auto
keyword, the port auto-negotiates only at the specified
speeds. Setting the speed without the auto keyword forces
the speed to the selected value and disables auto-
negotiation. It is possible to configure a fiber port for a
speed not supported by the transceiver. In this case, the
port will not link up.
On combo ports, it is possible to configure auto-
negotiation even if only the fiber interface is active. The
auto-negotiation settings will be utilized when the copper
port is active or a 1000BASE-X transceiver is inserted.
Fiber ports always operate in full-duplex mode.
