1. Log in to the system.
2. Check the "discard packets" statistical information of the output interface using the show qos queueing

3. If the statistical information identified in step 2 is incremented, packets are discarded through discarding control
and shaper of QoS control.
4. Review to see if discard control and shaper have been set up appropriately for the system operation.

2. Specify port list in the show shaper command and check the "discard_pkt" statistical information on user queue
of the input and output interfaces used for communication.
3. Specify interfaces in the show qos queuing command and check the "discard_pkt" statistical information on the
port transmission/reception queue of the input and output interfaces used for communication.
4. Specify interfaces in the show qos queuing command and check the "discard_pkt" statistical information on the
distribution transmission/reception queue of the input and output interfaces used for communication.
5. If the statistical information identified in step 2 to 4 is incremented, packets are discarded through discarding
control of QoS control.
