1  简介

本文档介绍使用QoS嵌套CBQ特性的典型案例。

2  配置前提

本文档不严格与具体软、硬件版本对应,如果使用过程中与产品实际情况有差异,请参考相关产品手册,或以设备实际情况为准。

本文档中的配置均是在实验室环境下进行的配置和验证,配置前设备的所有参数均采用出厂时的缺省配置。如果您已经对设备进行了配置,为了保证配置效果,请确认现有配置和以下举例中的配置不冲突。

本文档假设您已了解QoS特性。

3  配置举例

3.1  组网需求

图1所示,Host A,Host B和Host C在同一子网内,通过Router与Internet相连,均可访问Internet。现要求:

·     Host A、Host B、Host C访问Internet的总访问速率不能高于5Mbps。

·     其中Host A访问Internet的速率不低于2Mbps。

·     Host C在每日08:00到20:00时间段不能访问Internet。

3.2  使用版本

本举例是在Release 2311版本上进行配置和验证的。

3.3  配置思路

为了使主机能够按要求访问Internet,需要在路由器Router上分别配置QoS父策略和子策略,并将二者关联起来,最后将父策略应用在Router接口出方向上。

3.4  配置注意事项

·     在父策略行为下应用子策略时,最多只能嵌套一层策略,并且不能嵌套自己。

·     如果父策略和子策略中配置了相同的行为,先执行父策略的行为再执行子策略的行为。

·     如果子策略中配置了CBQ,那么父策略中必须配置GTS,并且配置的父策略GTS带宽必须大于子策略CBQ带宽,否则配置失败。

3.5  配置步骤

[Router] traffic classifier son_c

[Router-classifier-son_c] if-match acl 3003

[Router-qospolicy-son] quit

# 将子策略关联到父行为下。
