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.

smaller weights.
