Strict Priority
. The priority for packet passing egress port of switch depends on
the CoS value in
Port Classification
.
2
–8 Queues Weighted
. When congestion occurs, the priority for packet passing
egress port of switch depends on the proportion of total rate.
For example, select
Scheduler Mode
as
2 Queues
Weighted
. The max speed limit of
port 1 and port 2 is 500 kbps. When congestion occurs, 50% ingress port packet will
pass the egress port. See the following for the configuration:
1) Select
Scheduler Mode
as
2 Queues Weighted
2) In
Ingress Queue Shaper
, set the
Rate
of
Q0
and
Q1
to be 500 kbps, and
Rate-type
to be Line.
3) In
Egress Queue Shaper
, set the
Rate
to be 500 kbps, and
Rate-type
to be
Line
.
When congestion occurs and the speed of the two ports is 400 kbps, the speed
passing the egress port is 250 kbps.
