queue 3.
If port-based queue mapping mode is configured on a port, received packets are queued
according to the default priority of the port. The mapping between the default priority and
queues is consistent with that between 802.1p priority and queues.
The DIFF value relies on the DSCP in packets while the TOS/DIFF value depends on the
TOS/DSCP in packets. You can configure the mapping between priority and queues.
When a packet is tagged, the 802.1p value depends on the priority of 802.1Q in the
packet. When a packet is untagged, the 802.1p value depends on the default priority of
the port. You can configure the mapping between the 802.1p priority and queues.
When forwarding data, a port uses a scheduling mode to schedule the data of four queues
and the bandwidth of each queue. The switch supports two scheduling modes: Weighted
Round Robin (WRR), Hq-preempt mode, and STRICT mode.
WRR mode schedules data flows based on weight ratio. Queues obtain their bandwidths
based on their weight ratio. WRR prioritizes high-weight ratio queues. More bandwidths
are allocated to queues with higher weight ratio.
Hq-preempt mode forwards high-priority packets preferentially. It is mainly used for
transmitting sensitive signals. If a frame enters the high-priority queue, the switch stops
scheduling the low-priority queues and starts to process the data of the high-priority
queue. When the high-priority queue contains no data, the switch starts to process the
data of the queue with lower priority.
STRICT mode forwards high-priority packets preferentially. It is mainly used for
transmitting sensitive signals. If a frame enters the high-priority queue, the switch stops
scheduling the low-priority queues and starts to process the data of the high-priority
queue. When the high-priority queue contains no data, the switch starts to process the
data of the queue with lower priority.
