某单傡内部有200多个计算机终端上网，通过H3C MSR3620 路由器作为出口网关，由于有很多用户随意下载和浏览视频，很容易造成网络拥堵，通过调整带宽限速来解决问题。

      互联网接入为拔号上网，典型配置如下：

 telnet server enable

 dialer-group 1 rule ip permit
 dialer-group 2 rule ip permit
#

 bandwidth 100000
 ppp chap password cipher $c$3$fwpd22HVP4TVgwRXMaNSkBu+8H+N50LBVA==

 ppp pap local-user username@hrtn-jz password cipher password***

 dialer bundle enable

 增加流控策略，限制192.168.0.1-192.168.0.9 ，192.168.0.21-192.168.0.253 上传下载为2000M, 192.168.0.10-192.168.0.20 不限速
