交换机端口限速

配置入方向接口限速

配置名称为qoscar1的CAR模板指定限速带宽大小，并将该模板在接口GE1/0/1下应用。

[Quidway] qos car qoscar1 cir 10000 cbs 10240

[Quidway] interface gigabitethernet 1/0/1

[Quidway-GigabitEthernet1/0/1] qos car inbound qoscar1

配置出方向接口限速

在接口视图下执行命令qos lr cir cir-value [ cbs cbs-value ] [ outbound ]，对通过该接口的流量进行限速。









使用流策略进行限速:



根据IP地址进行限速

对IP地址为192.168.1.10的PC限速，带宽限制为4M。
