当前vlan201-TEL带宽为100M，那么限速在80M里比较合适，上载不限速；
打标先做连接标记，再做包的标记；
记得不管连接还是包标记都记得加方向，下载是in-interface=vlan201-TEL，上载是out-interface=vlan201-TEL；
包的大小分为0-1M,1M-3M,3M-6M,6M-无限大，优先级为别为1，2，3，4；
下载queue=pcq-download-default，上载queue=pcq-upload-default。
亲测效果比较佳！另外，如果需要对游戏不限速，需要添加游戏端口到fasttract。fasttract模式下限速无效
至于接口名称，请自行修改。速度值也需要做相应的修改
