iperf3命令使用

iperf3命令使用

1，iperf3安装

iperf3下载：https://iperf.fr/iperf-download.php#fedora

[root@localhost home]# rpm -ivhiperf3-3.1.3-1.fc24.x86_64.rpmPreparing...                         ################################# [100%]Updating / installing...  1:iperf3-3.1.3-1.fc24             ################################# [100%]

2，常用几种命令

服务器端：

[root@localhost home]# iperf3 -s

客户端：

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

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：
