Hello , I worked on the qos_sched application and I think, there may be an error in the config file. It seems that the allocation of the pipe profile mapping : - pipe 0-4095 = 0 ; These pipes are configured with pipe profile 0 is not in the right place. I think it should be in the subport configuration. For examples like this : ---------------------------------------------------------------------------------------------- [subport 0] number of pipes per subport = 4096 queue sizes = 64 64 64 64 64 64 64 64 64 64 64 64 64 pipe 0-4095 = 0 ---------------------------------------------------------------------------------------------- Moreover I did not find any parsing for the line : - subport 0-8 = 0 Thanks for your attention. Sincerely. Théo Margueret
