This document is not restricted to specific software or hardware versions. Procedures and information in the examples might be slightly different depending on the software or hardware version of the device.

The configuration examples were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

The following information is provided based on the assumption that you have basic knowledge of bandwidth management.

Restrictions and guidelines

When you configure bandwidth management, follow these restrictions and guidelines:

· Traffic policies support nesting, and can be nested for up to four levels.

· The maximum bandwidth for a child traffic policy must be smaller than or equal to that for its parent traffic policy.

· The guaranteed bandwidth for a child traffic policy must be smaller than or equal to that for its parent traffic policy.

· The traffic profiles cannot be the same for the child and parent traffic policies.

· An interface with small default expected bandwidth might experience traffic loss if the following conditions exist:

○ There is a large amount of traffic on the interface.

○ The interface uses the default expected bandwidth.

To avoid traffic loss, implicitly set the expected bandwidth to a large value for such an interface. For example, you can set the expected bandwidth of a tunnel interface to a value greater than 64 kbps (the default) if there is a large amount of traffic on the interface.

· If a traffic policy to be copied has child traffic policies, only the parent traffic policy is copied.

Example: Configuring a single traffic profile

Network configuration

As shown in Figure 1, configure bandwidth management on the device to meet the following requirements:

· The maximum bandwidth is limited to 30 Mbps for both upstream and downstream iQiYiPPS application traffic of the host in the intranet.

· The guaranteed bandwidth is 30 Mbps for both upstream and downstream FTP traffic of the host .

· The bandwidth of the interface to the Internet is limited to 100 Mbps.
