Configuring Traffic Prioritization
QoS Classification
The IE-SW-VL08M 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 IE-SW-VL08M shows
8 ports.)
Queuing Mechanism
Setting Description Factory Default
Weighted Fair
The Ethernet Switch
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
Enable/Disable
