Configuring Traffic Prioritization
QoS Classification
The PT-7324 supports inspection of layer 3 TOS and/or layer 2 QoS tag information to determine
how to classify traffic packets.
Queuing Mechanism
Setting Description Factory Default
Weighted Fair
The PT-7324 has 2 priority queues. In the weight fair
scheme, an 16:1, 8:1 or 4:1 weighting is applied to the
two priorities. This approach prevents the lower
priority frames from being starved of opportunity for
transmission with only a slight delay to the higher
priority frames.
Strict
In the Strict-priority scheme, all top-priority frames
egress a port until that priority’s queue is empty, and
then the next lower priority queue’s frames egress.
This approach can cause the lower priorities to be
starved of opportunity for transmitting any frames but
ensures all high priority frames to egress the switch as
soon as possible.
