Hi Team,

Thanks for the response,

$ ./build/qos_sched -c 0xe -n 4 -- --pfc "0,1,3,2" --cfg "profile.cfg"EAL: 
Detected 4 lcore(s)
PMD: bnxt_rte_pmd_init() called for (null)

EAL:   probe driver: 8086:10c9 rte_igb_pmd
EAL: Error - exiting with code: 1
  Cause: Cannot init mbuf pool for socket 0

I getting error something like this: Cannot init mbuf pool for socket 0.

$ grep -i Huge /proc/meminfo

Is 476 hugepages are sufficient to execute qos_sched application?

Could you help me in running this app as per my system configuration.

For this instance the application log is giving you a good instruction of where the problem might be, right? Please run the usertools/dpdk-devbind.py script to make sure that all the NIC ports you need are handled by DPDK. Please make sure you have the root privileges to run this app, huge pages are required.

> For qos_sched sample application require more than one NUMA node?

No. Please take a look at the user guide on how to run this sample app: http://www.dpdk.org/doc/guides/sample_app_ug/qos_scheduler.html
