Example for Configuring HQoS (Subscriber Queues Configured Based on ACLs)
Networking Requirements
Voice, video, and data services from multiple users are transmitted on a network, and 802.1p priorities of voice, video, and data services are 6, 5, and 2 respectively. Bandwidth needs to be guaranteed for the voice, video, and data services in descending order of priority. Table 11-6 and Table 11-7 describe the configuration requirements.
Because the bandwidth is limited, the device needs to differentiate service priorities and shape traffic from different users to provide different bandwidth. Table 11-8 describes the configuration requirement.

Configuration Roadmap
The configuration roadmap is as follows:
- Create VLANs and configure interfaces so that the users can access the Internet through the Switch.
- Create a DiffServ domain on the Switch, map the 802.1p priorities of different service packets to PHBs and color, and bind the DiffServ domain to the inbound interface of the Switch.
- Configure a flow queue WRED drop profile, flow queue profile, and profile parameters on the Switch so that the Switch provides different scheduling priorities, drop profile parameters, and traffic shaping parameters for different services.
- Configure ACLs on the Switch to differentiate service traffic of different users based on VLAN IDs.
- Configure subscriber queues and traffic shaping parameters on the Switch, and reference the flow queue WRED drop profile and flow queue profile to implement HQoS.
Procedure
- Create VLANs and configure interfaces.
