discard_pkt
statistics item displayed for the port input and output queues of the input
and output interfaces used for communication.
3. Execute the
show qos queueing command with the distribution parameter, and check
the
discard_pkt statistics item displayed for the distribution input and output queues for
the input or output interface used for communication.
4. If the counts of the statistics items checked in steps 2 and 3 are incremented, packets are
discarded by QoS control drop control.
5. Check whether drop control and the legacy shaper are being used appropriately in the
system configuration.
For AX3800S, AX3600S, and AX2400S series switches:
1. Log in to the Switch.
2. Use the
show qos queueing command to check the information displayed for discard
packets in the output interface statistics.
3. If the count of the statistics item checked in step 2 is incremented, packets are discarded
by drop control and the QoS control legacy shaper.
4. Check whether drop control and the legacy shaper are being used appropriately in the
system configuration.
(4) Checking whether packets have been discarded by drop control and the QoS control
hierarchical shaper
For AX6700S, AX6600S, and AX6300S series switches:
1. Log in to the Switch.
2. Execute the
show shaper command with the port list parameter, and check the
discard_pkt statistics item displayed for the user queues of the input and output
interfaces used for communication.
3. Execute the
show qos queueing command with the interface parameter, and check the
discard_pkt statistics item displayed for the port input and output queues of the input
and output interfaces used for communication.
4. Execute the
show qos queueing command with the distribution parameter, and check
the
discard_pkt statistics item displayed for the distribution input and output queues for
the input or output interface used for communication.
5. If the counts of the statistics items checked in steps 2 to 4 are incremented, packets are
discarded by QoS control drop control.
6. Check whether drop control and the hierarchical shaper are being used appropriately in
the system configuration.
