Please follow the below steps
- Set up the iperf client as a laptop/pc behind the lan of this site
- Set up the iperf server on a laptop/pc behind the lan of a remote site
Set up the server machine as below
root@speedtest:/home/esundberg# iperf3 -s -p 5001 -i 5
Perform the speed on the Client machine as below (replace x.x.x.x with the ip-address of the servcer machine)
C:\temp\iperf>iperf3 -u -b 4000M -c x.x.x.x -p 5001 -l 1400
C:\temp\iperf>iperf3 -u -b 4000M -c x.x.x.x -p 5001 -l 1400 -R (this will test the speed in the “reverse” direction)
Just before you start the speed test, please start the below on the local and remote site (please ensure it’s taken on both the sites)
admin@Flex3-cli> show interfaces port statistics brief | nomore | repeat 2 << on putty terminal 1
admin@Flex3-cli> show class-of-services interfaces extensive | nomore | repeat 2 << on putty terminal 2
It’s best if you perform these tests during “non-production” hours so that the only traffic on the link would be the iperf generated traffic
Sample results from a lab machine are as below
