四、查看配置信息
3550#show run
policy-map 5m
class dkxs
police 5000000 500000 exceed-action drop
policy-map 1m
class dkxs
police 1000000 100000 exceed-action drop
policy-map 80k
class dkxs
police 80000 8000 exceed-action drop
policy-map 10m
class dkxs
police 10000000 1000000 exceed-action drop
五、通过iperf软件进行验证
即先在一台服务器上运行iperf的服务器端,命令如下:
F:\tools>iperf -s
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 8.00 KByte (default)
------------------------------------------------------------
然后在交换机的22口上分别应用表示不同速率的policy-map,每应用一次,通过一台连接到22端口的笔记本电脑运行iperf的客户端,进行端口速率测试,结果分别如下:
(交换机设置)
3550(config-if)#service-policy input 80k
(IPERF客户端测试结果)
F:\tools>iperf -c 10.66.66.8

为了使测试的结果更准确,每种速率下都进行了两次测试,从测试的结果看,端口限速确实生效了。
