by the classifier profile set rule priority command). This value determines the scheduling
behavior received by a packet. If a packet is not classified, scheduling priority 0 is assigned
to the packet by default.
If you select the priority service discipline, the profile supports 8 queues, each corre-
sponding to a scheduling priority from 0-7. Each queue can hold a maximum of 32 pack-
ets at any instant. Scheduling priority value 0 assigns the lowest priority while 7 assigns
the highest priority.
If you select the WF2QPlus service discipline, the weight value (percentage) configured
for a scheduling priority determines the share of bandwidth received by packets belong-
ing to the scheduling priority level. A single default queue with a weight of 100% is cre-
ated by default. Packets with scheduling priority 0 are always enqueued in the default
queue. You may configure weights for scheduling priority levels (1-7) using the scheduler
profile set queue weight command.
If you do configure weight for a scheduling priority level, the corresponding packets are
enqueued in a separate queue and the bandwidth is allocated in accordance with the con-
figured weights. Otherwise, packets are enqueued in the default queue.
Each queue can hold a maximum of 32 packets at any instance.
In addition, this created scheduler profile may be configured with shaping and algorithmic
dropper (RED/WRED):
• Shaping: you can configure the scheduler profile for shaping by using the scheduler
set profile shaping command. Shaping is disabled by default.
• Algorithmic Dropper: you can configure Algorithmic Dropper (RED/WRED) for a
queue by using the scheduler profile set queue ald profile command.
You can set the profile to work on a transport by using the transport set scheduler pro-
file command.
