ADSL：外网接口
qiao：桥接口，或者是内网网卡接口。如果有多个内网网卡，建立放在一个桥内管理，或者采用交换机模式管理。

端口
8291,20-25,110,1720-1723,3389,3306,3690,15906,35719请修改成你要优先的端口。

192.168.88.0/24 修改成您自己的网段。（代码为上行512K，下行8M的代码）
limit-at=128k/1M //这行的意思是保证上行128K，下行1M。
max-limit=500k/8M //这行的意思是最大上行和下行，这里我取的是最大。pcq-upload-default/pcq-download-default 这是默认的，不需要做什么修改。（本文属于原创，转载请注明出处：http://www.znl.net）
这里多说几句，要做PCQ，一定要在simple queue里做。那些人在queue tree中做，虽然有一点效果，但只是起到了htb的作用，却没有pcq的作用，pcq是基于IP来做的。
纯属自己理解，勿喷。
OK！请尽情的享受吧。
补充阅读#
补充 RouterOS 6.0 单线 QoS 配置的阅读顺序，说明接口、网段和优先端口的替换位置。
如何理解与使用#
先读 mangle 标记，再读队列如何引用标记；ADSL、桥接口与内网网段是这份配置的重要环境参数，不能只替换其中一个。
验证与边界#
用真实流量检查各标记是否命中，并在链路繁忙时比较优先业务与普通业务表现。文中端口和带宽属于历史示例，应按当前需求调整。
