Hi everyone, I want to perform tests by creating different numbers of
flows. Are
there any commands that I can see the number of flows I have created? Also,
where can I find flow samples created in different numbers? I could get
very little information in the document. For example how do I create 1000
or 10000 flows?

Hi everyone, I will get flows using the "range" command. So I am reviewing
documents and sample codes about this topic. I would like to ask a few
things that I cannot understand. What is the flow generation procedure of
range command? Take port 0 as an example. 128 different ip addresses and
2000 different port numbers are used for source and destination. As far as
I understand, these lines are repeated for each package.But how is the flow
creation procedure?
My opinions:
First: Is it a random port number and ip address for each pass over the
file? So total 128 * 2000= 256000 flows were created here.
Second: when we think of increment operator, generated packets:
1. packet:  dst_ip: 192.168.1.1  ,  src_ip:  192.168.0.1 , dst_port: 2000 ,
src_port: 5000
2. packet   dst_ip: 192.168.1.2  ,  src_ip:  192.168.0.2 , dst_port: 2001 ,
src_port: 5001
................................
128. packet:   dst_ip: 192.168.1.128  ,  src_ip:  192.168.0.128 , dst_port:
2128 , src_port: 5128
129.packet      dst_ip: 192.168.1.1  ,  src_ip:  192.168.0.1 , dst_port:
2129, src_port: 5129  or (???)  dst_ip: 192.168.1.128  ,  src_ip:
192.168.0.128 , dst_port: 2129, src_port: 5129

then it will end when source and destination port numbers reach their
highest value..

........
Can you help with this issue? I want to measure the performance of the
system that I have created in different flow numbers with the pktgen tool.
For this reason, the number of flows is important for me. Thanks for your
help.
