WX5002的用户流量限速CAR功能的典型配置

WX5002的用户流量限速CAR功能的典型配置

适用WX5002版本：Comware Software, Version 5.20, Release 1106P01                                   

一、组网需求

WX5002、WA2110、H3C POE交换机、便携机（安装有11b/g无线网卡）

二、组网图

WX5002的IP地址为192.168.1.9。

交换机为三层交换机，WX5002和WA2110在VLAN 1，服务器在VLAN100。

VLAN1和VLAN100的接口地址分别是192.168.1.254和192.168.100.254。

本例中WA2110的序列号为210235A22W0077000088。

使用的SSID的名称为H3C-Car。

无线客户端MAC地址为0019-d221-a8d6，限制此客户端的上行流量为500K。

四、验证结果

在无线网络中，QoS策略需要在无线用户上线之前配置，无线用户上线后相应的QoS策略才会生效。在完成上述配置后，可通过以下方式验证上述配置：

用IxChariot打流量，流量方向为无线客户端到服务器192.168.100.10，通过IxChariot的流量图可以明确地看出无线客户端的上行流量被限制在500K左右。

以下为没有限制客户端上行流量时的流量图，可以看到此时客户端的上行流量为20M左右。
