Usage Guidelines

Usage Scenario

To improve system performance, you can decrease the packet sending bandwidth of a DCN interface to reduce CPU usage when the device is heavily loaded but increase the packet sending bandwidth to raise CPU usage when the device is lightly loaded.

The bandwidth command helps modify the packet sending bandwidth of a DCN interface based on CPU usage.

NOTE:

The bandwidth command is supported only in transport mode.

Precautions

In VS mode, this command is supported only by the admin VS.

Example

# Configure the packet sending bandwidth of a DCN Ethernet interface as 512 kbit/s.
