For UDP (-u) the -l on the client defines the UDP payload size.  A 1470
byte UDP payload will generate the max ethernet frame for ipv4 and 1450
bytes for ipv6.

TCP is a byte protocol where there is no direct control of a layer 2
packet's frame size.   The -l sets the write() size, -w the window size, -M
the maximum segment size and the MTU size is set on an interface per the
operating system.

[Iperf-users] Framesize

2019-05-29 Thread Sudeep Gupta
Hi,

I want to run a test using a fixed framesize. I couldn't find an option to
set the framesize in iperf documentation. Can someone point me to the
parameter which can specify framesize?

Regards,
Sudeep
