该公司有两个内网段：192.168.0.0/24，192.168.1.0/24。
192.168.0.0/24为低优先级内网段，192.168.1.0/24为高优先级内网段。
在class-map中premium_class类包括了192.168.1.0/24高优先级内网段，采用NBAR匹配实时性较高的应用如：napster、netshow、pcanywhere、realaudio、streamwork、vdolive、cuseeme、telnet、Http等。normal_class类包括了192.168.0.0/24低优先级内网段，采用NBAR匹配实时性不强的应用如：ftp、pop3、smtp等。
在policy-map中针对不同的class，采取不同的策略。如：CBWFQ、WRED等。因为我公司互联网带宽为2M，故考虑WRED中的指数加权因子为4，最小阀值为5，最大阀值为17，标记几率分母为1。
在route-map（PBR）中采用匹配不同的ACL 110#,ACL 120#。设置不同的IP precedence值。
在F 0/0以太口上增加inbound policy--ACL 130#，在上班时间8:30到18:00禁止BT下载。限制震荡波病毒的端口。
在S 0/0串口上采用Input CAR策略。对进入S 0/0串口的流量进行整形。
