Dimension ES-3124 Ethernet Switch
Queuing Method 18-3
The following table describes the labels in this screen.
Table 18-1 Queuing Method
LABEL DESCRIPTION
Method Select Strictly Priority or Weighted Fair Scheduling.
Strictly Priority services queues based on priority only. When the highest priority queue empties,
traffic on the next highest-priority queue begins. Q7 has the highest priority and Q0 the lowest.
Weighted Fair Scheduling is used to guarantee each queue’s minimum bandwidth based on
their bandwidth portion (weight) (the number you configure in the Weight field). Queues with
larger weights get more guaranteed bandwidth than queues with smaller weights.
FE Port SPQ
Enable This field is applicable only when you select Weighted Fair Scheduling.
Select a queue (Q0 to Q7) to have the switch use Strictly Priority to service the subsequent
queue(s) after and including the specified queue for the 10/100 Mbps Ethernet ports. For
example, if you select Q5, the switch services traffic on Q5, Q6 and Q7 using Strictly Priority.
Select None to always use Weighted Fair Scheduling for the 10/100 Mbps Ethernet ports.
Port This label shows the port you are configuring.
Weight When you select Weighted Fair Scheduling, enter the queue weight here. Bandwidth is divided
across the different traffic queues according to their weights.
For Gigabit ports, if you enter 0 for the queue weight, the switch uses Strictly Priority to service
the queue.
