Chapter 22 Interface Configuration
22.1 Configuring Interface Common Attribute
The following content describes the command that can be executed on an interface of any type
and configures common attributes of interface. The common attributes of interface that can be
configured include: interface description, bandwidth and delay and so on.
22.2 Adding Description
Adding description about the related interface helps to memorize content attached to the interface. This
description only serves as the interface note to help identify uses of the interface and has no effect on any
feature of the interface. This description will appear in the output of the following commands: show running-
config and show interface. Use the following command in interface configuration mode if user wants to add a
description to any interface.
Command Purpose
description
string Adds description to the currently-configured interface.
For examples relevant to adding interface description, please refer to the following section ‘Interface
Description Example’.
22.2.1 Configuring Bandwidth
The upper protocol uses bandwidth information to perform operation decision. Use the following command to
configure bandwidth for the interface:
Command Purpose
bandwidth
kilobps Configures bandwidth for the currently configured
interface.
The bandwidth is just a routing parameter, which doesn’t influence the communication rate of the actual
physical interface.
22.2.2 Configuring Time Delay
The upper protocol uses time delay information to perform operation decision. Use the following command to
configure time delay for the interface in the interface configuration mode.
Command Purpose
delay
tensofmicroseconds Configures time delay for the currently configured
interface.
The configuration of time delay is just an information parameter. Use this command cannot adjust the actual
time delay of an interface.
22.3 Monitoring and Maintaining the Port
To maintain and monitor the interface, perform the following tasks:
