To communicate the bandwidth value of an interface to the higher-level protocols, use the bandwidth interface configuration command. Use the no form of this command to restore the default values.
bandwidth kilobits
no bandwidthSyntax Description
kilobits Intended bandwidth in kilobits per second. Default
Default bandwidth values are set during startup and can be displayed with the EXEC command show interfaces.
Command Mode
Interface configuration
Usage Guidelines
This command first appeared in Cisco IOS Release 10.0.
The bandwidth command sets an informational parameter to communicate the current bandwidth to the higher-level protocols.
IGRP uses the minimum path bandwidth to determine a routing metric. The TCP protocol adjusts initial retransmission parameters based on the apparent bandwidth of the outgoing interface.
At higher bandwidths, the value you configure with the bandwidth command is not what is displayed by the show interface command. The value shown is that used in IGRP updates and also used in computing load.
Note: This is a routing parameter only; it does not affect the physical interface.
Example
The following example sets the full bandwidth for DS3 transmissions:
interface serial 0 bandwidth 44736
