Configuring Traffic Prioritization
QoS Classification
The EDS supports inspection of layer 3 TOS and/or layer 2 QoS tag information to determine how
to classify traffic packets. (NOTE: The user interface for the EDS-408A shows 8 ports.)
Queuing Mechanism
Setting Description Factory Default
Weighted Fair
The EDS-408A/405A has 4 priority queues. In the
weight fair scheme, an 8, 4, 2, 1 weighting is applied
to the four 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.
Weight Fair
Inspect TOS
Setting Description Factory Default
