When I ran the iperf command with -b bandwidth option, it always has the following warning message

WARNING: option -b implies udp testing

Is there a way to let the command not display this warning message?

Hi,

The "-b" option is used for  UDP bandwidth to send at, in bits/sec. This implies the -u option. Default is 1 Mbit/sec.

What command are you using? The sample command should be;

node1> iperf -c node2 -u -b 10m
