Description
Strict – Services the egress queues in sequential order, transmitting all
traffic in the higher priority queues before servicing lower priority
queues. This ensures that the highest priority packets are always serviced
first, ahead of all other traffic.
WRR– Shares bandwidth at the egress ports by using scheduling weights,
servicing each queue in a round-robin fashion.
Strict and WRR – Uses strict priority on the high-priority queues and
SDWRR for the rest of the queues. (This is the default setting.)
The ID of the priority queue. (Range: 0-3)
If "Strict and WRR" mode is selected, then a combination of strict service is
used for the high priority queues and weighted service for the remaining
queues. Use this parameter to specify the queues assigned to use strict
priority when using the strictweighted queuing mode. (Default: Strict and
WRR mode, with Queue 3 using strict mode)
Sets a weight for each queue which is used by the SDWRR scheduler.
(Range: 1-255; Default: Weights 1, 2, 4, 6 are assigned to queues 0 - 3
respectively)
