Configuring HQoS on a Low-speed Links Interface

Configuring HQoS on a Low-speed Links Interface

In HQoS, synchronous serial interfaces of the E1 channel are configured for a CPOS interface or an E1 interface. In this case, each user can access the network through a synchronous serial interface, better utilizing the interface bandwidth.

Usage Scenario

HQoS is mostly used on the user side of

  • A PE device of a backbone network

  • An access router of an access network.

In the case of multiple user access and multiple service access, HQoS can differentiate users in a network for priority scheduling and bandwidth guarantee. In addition, HQoS can also save the costs in network operation and maintenance.

Pre-configuration Tasks

Before configuring HQoS, complete the following tasks:

  • Configuring IP addresses for the interfaces

  • Configuring IP routing protocol on the routers and ensure that the link works normally

  • Configuring simple traffic classification


Before you configure the HQoS function, it is recommended that you configure the simple traffic classification or complex traffic classification; otherwise, in FQ scheduling all traffic is considered BE by default.
