The following table describes the labels in this screen.
Table 41 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.

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.
