Determines the weight factor T_WFQ of the queue at the WFQ
scheduler input to which it is connected. Refer to Section 4.2.2.7
“Guaranteed Cell Rates and WFQ Weight Factors” on
Page 114.
The value WFQ Factor = 0 connects the queue to the high priority
Round Robin Scheduler.
The value WFQFactor = 16383 (all ones) connects the queue to the
low priority Round Robin Scheduler.
Modifying the WFQFactor during operation:
• If one of the Round Robin Schedulers (WFQFactor=0 or
WFQFactor=16383) is used the WFQFactor must not be
changed
• If the WFQ Scheduler (WFQFactor=1..16320) is used the WFQ-
Factor may be varied in a range 1 to 16320.
