and one packet from LOW priority queue.
2 Four packets are sent from the HIGH priority queue
and one packet from LOW priority queue.
3 Six packets are sent from the HIGH priority queue

The command displays the QoS settings

show qos [type=<port|tag|tos>] [port=<port|list|range>]
Sometimes it is necessary to change the priority of the packets going out of a switch. For
example, when a packet is received untagged and has to be transmitted with an addition
of the 802.1p priority tag, the tag can be assigned depending on the
example if the command is set to
untag
received on that port will be tagged with a priority low upon transmit.
The command defines the 802.1p user priority assigned to untagged received
untag
packets to be transmitted as tagged from the priority queue.
