bandwidth

Function

The bandwidth command sets configuration bandwidth for an interface.

The undo bandwidth command cancels the configuration bandwidth set for an interface.

By default, no configuration bandwidth is set for an interface.

Usage Guidelines

Usage Scenario

Interface bandwidth is classified as physical bandwidth or configuration bandwidth. The bandwidth command sets configuration bandwidth for an interface, which does not affect the physical bandwidth of the interface. To view the command configurations, you can check the ifSpeed and ifHighSpeed objects in the IF-MIB on the NMS.

If the configured bandwidth is smaller than 4000 Mbit/s, ifSpeed and ifHighSpeed are respectively displayed as bandwidth×1000×1000 and bandwidth.
If the configured bandwidth is equal to or larger than 4000 Mbit/s, ifSpeed and ifHighSpeed are respectively displayed as 4294967295 (0XFFFFFFFF) and bandwidth.

Precautions

A main interface's bandwidth determines the default sub-interface bandwidth.

If the bandwidth command is run more than once, the latest configuration overrides the previous one.

Example

# Set the configuration bandwidth of Eth-Trunk1 to 512 Kbit/s.

<HUAWEI> system-view
[HUAWEI] interface Eth-Trunk 1
[HUAWEI-Eth-Trunk1] bandwidth 512 kbps

# Set the configuration bandwidth of GE 0/1/0 to 10000 Mbit/s.

<HUAWEI> system-view
[~HUAWEI] interface GigabitEthernet 0/1/0
[*HUAWEI-GigabitEthernet0/1/0] bandwidth 10000
