Bandwidth Command on CISCO Router/Switch

Command

Bandwidth

Use

This command is used to logically set the bandwidth of an interface. This does not affect the physical speed of the link, it only affects routing protocols and other technologies that use bandwidth as a calculation.

Syntax

Router(config-if)#bandwidth <kilobits>

Example

In this example, we change R1’s Fa0/0 interface to have a logical bandwidth of 768 kbs.

R1(config-if)#do show int fa0/0 | in BW
MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec,
R1(config-if)#
R1(config-if)#bandwidth 768
R1(config-if)#do show int fa0/0 | in BW
MTU 1500 bytes, BW 768 Kbit, DLY 100 usec,
