配置基于模板的HQoS示例
根据不同的子接口接入不同业务的流量，以基于模板的场景为例，介绍如何配置HQoS示例。
组网需求
用户通过DSLAM接入路由器，路由器为骨干网的接入设备。如图8-4所示。
用户的三个业务映射到DSLAM的3个PVC中，在路由器上同一用户的流量分别通过GE0/1/0.1、GE0/1/0.2和GE0/1/0.3三个子接口上接入，不同的子接口接入不同业务的流量。流量进入路由器时带有两层tag，内层tag表示用户，外层tag表示业务。要对用户的流量进行统一调度，保证带宽为100M，其中EF流量带宽为30M、AF1流量带宽为10M。用户所属用户组的总带宽为500M。在接入路由器下行接口EF类型的报文流量不能超过120M。同时，业务类型PC、VOIP和IPTV分别标记外层VLAN tag为1、2、3；内层VLAN tag均为1～100。
本例中Subinterface1.1，Subinterface2.1，Subinterface3.1，interface2分别代表GE0/1/0.1，GE0/1/0.2，GE0/1/0.3，GE0/2/0。
配置思路
采用如下的思路配置基于模板的HQoS功能。
配置流队列WRED对象的报文丢弃的参数。
配置流队列的调度算法及参数。
配置用户组队列shaping值。
配置业务模板的精度调整长度。
配置QoS模板中用户队列调度参数。
配置类队列WRED对象的报文丢弃的参数。
在接入路由器下行接口配置类队列。
数据准备
完成此例配置，需准备以下数据：
flow-wred报文丢弃的参数
flow-queue调度算法及其参数
user-group-queue的shaping值
QoS模板中user-queue CIR、PIR和network-header-length的值
QoS模板应用的接口
port-queue引用的port-wred的参数
port-queue调度算法及其参数、shaping值
操作步骤
- 配置流队列引用的WRED对象
# 配置flow-wred报文丢弃的参数。
