Example for Configuring Priority-based Shaping for a GQ

This section provides an example for configuring priority-based shaping for a GQ.

Networking Requirements

Assume that there are N QinQ users. Use users test1 and test2 as an example. The PE VLAN ID and CE VLAN ID of user test1 are 1 and 100 respectively, and the PE VLAN ID and CE VLAN ID of user test2 are 1 and 200 respectively. The bandwidths of the EF and BE queues are respectively 1 Mbit/s and 100 Mbit/s for user test1 and are respectively 2 Mbit/s and 200 Mbit/s for user test2. It is required that the bandwidth be guaranteed for priority-specific queues of all users and the traffic rate be restricted to 5 Mbit/s for EF queues of all users in the GQ and to 600 Mbit/s for BE queues of all users in the GQ.

Subinterface1.1, Subinterface2.1, Interface2 in this example are GigabitEthernet0/1/0.1, GigabitEthernet0/1/0.2 and GigabitEthernet0/1/8, respectively.

Configuration Roadmap

The configuration roadmap is as follows:

Configure flow WRED objects.
Configure scheduling algorithms and parameters for the user test1 flow queue.
Configure scheduling algorithms and parameters for the user test2 flow queue.
Configure priority mapping and shaping values for the GQ.
Configure user-queue scheduling parameters for user test1.
Configure user-queue scheduling parameters for user test2.
Configure a QoS profile for user test1 on the outbound interface of the router.
Configure a QoS profile for user test2 on the outbound interface of the router.

Data Preparation

To complete the configuration, you need the following data:

Scheduling algorithms and related parameters for flow queues
Shaping values for a group queue
Applied interface

HQoS must be applied to outgoing packets on an interface.
The cir cir-value must be set to 0.
The configuration of priority-based shaping for a GQ can be bound to a priority-based FQ profile only.

Procedure

Configure a WRED object referenced by a flow queue.

[*HUAWEI-flow-queue-template-test2] commit
[~HUAWEI-flow-queue-template-test2] return

Configure priority mapping and shaping values for the GQ.

<HUAWEI> system-view
[~HUAWEI] user-group-queue test priority-mode
[*HUAWEI-user-group-queue-test] priority 1 shaping 5000 outbound
[*HUAWEI-user-group-queue-test] priority 2 shaping 600000 outbound
[*HUAWEI-user-group-queue-test] commit
[~HUAWEI-user-group-queue-test] return

Configure user-queue scheduling parameters.

Configure user-queue scheduling parameters for user test1.

<HUAWEI> system-view
[~HUAWEI] qos-profile test1
[*HUAWEI-qos-profile-test1] user-queue cir 0 pir 2000000 flow-queue test1 user-group-queue test outbound
[*HUAWEI-qos-profile-test1] commit
[~HUAWEI-qos-profile-test1] return

Configure user-queue scheduling parameters for user test2.

<HUAWEI> system-view
[~HUAWEI] qos-profile test2
[*HUAWEI-qos-profile-test2] user-queue cir 0 pir 2000000 flow-queue test2 user-group-queue test outbound
[*HUAWEI-qos-profile-test2] commit
[~HUAWEI-qos-profile-test2] return

Apply the configuration to an interface.

Create a QinQ sub-interface, configure QinQ termination for the sub-interface, and apply the user test1 configuration to interface 0/1/0.1.

<HUAWEI> system-view
[~HUAWEI] interface gigabitethernet 0/1/0.1
[*HUAWEI-GigabitEthernet0/1/0.1] encapsulation qinq-termination

[*HUAWEI-GigabitEthernet0/1/0.1] commit
[~HUAWEI-GigabitEthernet0/1/0.1] quit

Create a QinQ sub-interface, configure QinQ termination for the sub-interface, and apply the user test2 configuration to interface 0/1/0.2.

<HUAWEI> system-view
[~HUAWEI] interface gigabitethernet 0/1/0.2
