2,常用几种命令

服务器端:

[root@localhost home]# iperf3 –s

客户端:

iperf3: interrupt - the client hasterminated

解释:

默认情况客户端使用TCP协议

-s:指明是服务器端

-c: 指明是客户端

192.168.0.222为服务端IP地址

iperf3: interrupt - the client hasterminated

解释:

-u:指定是udp报文

-b:指定发送带宽大小。

 

服务器端:

[root@localhost home]# iperf3 -s -p 2480

客户端:

iperf3: interrupt - the client hasterminated

解释:

-p:指定端口
