.. note::
To get statistics on the sample app using the command line interface as described in the next section,
- DPDK must be compiled defining *CONFIG_RTE_SCHED_COLLECT_STATS*,
- which can be done by changing the configuration file for the specific target to be compiled.

Interactive mode
~~~~~~~~~~~~~~~~
.. code-block:: console
- ./qos_sched -l 1,5,7 -n 4 -- --pfc "3,2,5,7" --cfg ./profile.cfg
+ ./<build_dir>/examples/dpdk-qos_sched -l 1,5,7 -n 4 -- --pfc "3,2,5,7" --cfg ./profile.cfg
This example uses a single packet flow configuration which creates one RX thread on lcore 5 reading
from port 3 and a worker thread on lcore 7 writing to port 2.
.. code-block:: console
- ./qos_sched -l 1,2,6,7 -n 4 -- --pfc "3,2,2,6,7" --pfc "1,0,2,6,7" --cfg ./profile.cfg
+ ./<build_dir>/examples/dpdk-qos_sched -l 1,2,6,7 -n 4 -- --pfc "3,2,2,6,7" --pfc "1,0,2,6,7" --cfg ./profile.cfg
Note that independent cores for the packet flow configurations for each of the RX, WT and TX thread are also supported,
providing flexibility to balance the work.
