•
wfq
- Weighted Fair Queueing shares bandwidth at the egress
ports by specifying a minimum bandwidth for each queue.
Guaranteed bandwidth is first supplied to each queue, any
remaining bandwidth is distributed in a round-robin fashion.
•
wrr
- Weighted Round-Robin shares bandwidth at the egress ports
by using scheduling weights.
•
strict-wfq
- Strict priority is used for the high-priority queues and
Weighted Fair Queueing for the rest of the queues.
• strict-wrr
- Strict priority is used for the high-priority queues and
Weighted Round-Robin for the rest of the queues.
•
sp-queue
- Specifies the strict priority queues used for the
strict-wrr
and
strict-wfq
options. This assigns the specified
queue up to the highest priority queue. (Range: 0-7)
Default Setting
Strict priority

Command Usage
• The ECN330-switch can be set to service the port queues based on
strict priority, WFQ, WRR, or a combination of strict and weighted
queueing.
• Strict priority requires all traffic in a higher priority queues to be
processed before lower priority queues are serviced.
• WFQ shares bandwidth at the egress ports by specifying a minimum
bandwidth for each queue. Guaranteed bandwidth is first supplied to
each queue, any remaining bandwidth is distributed in a round-robin
fashion. Use the
queue min-bandwidth
command (section 7.19.4 on
page 903) to assign the minimum bandwidth to each of the eight priority
queues.
• WRR queuing specifies a relative weight of each queue. WRR uses a
predefined relative weight for each queue that determines the
percentage of service time the ECN330-switch services each queue
