Step 3 Select mode.
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. See Figure 3-57.
2) In Ingress Queue Shaper, set the Rate of Q0 and Q1 to be 500 kbps, and Rate-type to
be Line.
In Egress Queue Shaper, set the Rate to be 500 kbps, and Rate-type to be Line.
3)
When congestion occurs and the speed of the two ports is 400 kbps, the speed passing
the egress port is 250 kbps.
