EDS-828 Series Featured Functions
3-39
The EDS-828 supports inspection of layer 3 TOS and/or layer 2 CoS tag information to determine how to
classify traffic packets.
Queuing Mechanism
Setting Description Factory Default
Weighted Fair The EDS-828 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.
Weight Fair
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.
Inspect TOS
Setting Description Factory Default
Enable/Disable Check the checkbox to enable the EDS-
828 to inspect the Type
of Service (TOS) bits in IPV4 frame to determine the priority of
each frame.
Enable
Inspect COS
Setting Description Factory Default
Enable/Disable Check the check box to enable the EDS-828 to inspect the
802.1p COS tag in the MAC frame to determine the priority of
each frame.
Enable
Default Port Priority
Setting Description Factory Default
Low/Normal/
Medium/High
Set the Port Default Priority of the ingress frames to different
priority queues. If the received packets are not equipped with
any tag information (CoS, TOS) the default port priority will
take effect.
Normal
NOTE
The priori
ty of an ingress frame is determined in order by:
1. Inspect TOS
2. Inspect CoS
3. Default Port Priority
NOTE
The designer can enable these classifications individually or in combination. For instance, if a ‘hot,’ higher
priority port is required for a network design, “Inspect TOS” and “Inspect CoS” can be disabled. This setting
leaves only port default priority active, which results in all ingress frames being assigned the same priority on
that port.
