Install iperf3


Code Block
titleNode
lsb_release -a

on Debian:
apt-get install  iperf3


Speed test:

Run an iperf UDP stream with at specific rate (in Mbps):




Code Block
titleiperf

...

# iperf3 –u -p <listening port> –c <server IP@> -b <X>m -d

...

# iperf3 –u –p <listening port> –s 

-u : UDP packet , best for bandwitdh test
-c it's the Client side
-s it's the Server side
-p destination port number on the client side
( or listening port number on the server side)
-b for bandwidth ( default 1m)  
-d for dualtest ( bi-directional)  >> becarefull at the ID number in the report


Speed test:

Run an iperf UDP stream with at specific rate (in Mbps):

Start an iperf UDP server:       # 

...

iperf3 –u –p <listening port> –s           # 

...

iperf3 –u –p 80 –s

Then on the client:                   # 

...

iperf3 –u –p <listening port> –s           # 

...

iperf3 –u -p 80 –c 10.1.0.3  –b 200m

unlimited

The -t 0 option indicates an unlimited test duration.

root@R4PLAB:/home/ocnos# iperf3 -c 10.10.10.10 -t 0


Single test: Client to Server


1- note the different port for the signaling and the data traffic?????
