Re: [HELP] for using class group classifier network controller

when I set the classid to 0x10010, class 1:10's packet count was increased. 
But, according to your configuration, every packet has to flowed to 1:10 class. 
Yes, you are right.
Of course I know that the net_cls can't classify all packet because of the getting classid from the current task. 
Even though we consider it, Many packets are flowed to 1:30 class. 
therefore, the rate of the socket showed about 30mbps. This is the 1:30 class's rate.
I think it's because that 1:30 class is the default class. 
When I changed the default to 20, the rate was varied to 20mbps, class 1:20's rate.


To measure this rate, I used the iperf and scp command. Two results are the same.
How about your experiment's result? 
Would you check the accurate rate of the network using applications like a iperf?
I did same experience with nuttcp, I observed the same result, too.
(Almost packets were classified into default classid.)
 
By the results of my experiments, net_cls couldn't control the network rate of the group. 
What is your opinion?
I agree with you.
I'm going to investigate this problem.
