Queue-Servicing Algorithms
The following queue-servicing algorithms are available for egress queues:
■
Weighted fair queueing (WFQ)
■
Strict Priority
■
Class-based queueing (CBQ)
■
Class-based weighted fair queueing (CBWFQ)
* Note: In earlier versions of the switch software, you could set ingress
queues to use the weighted fair queuing (WFQ) and strict
priority queue-servicing algorithms. In v5.3.1 and later, you can
set only egress queues to use these queue-servicing algorithms.
To service ingress queues, use the policing feature.

How WFQ Works
WFQ is the default queue-servicing algorithm. When a port is set to use the
WFQ algorithm, each queue:
WFQ algorithm, each queue:

Is assigned a weight increment. This value never changes.

Maintains an accumulated weight. After the switch services a
queue, its accumulated weight is reset to the value of its weight
increment, and the accumulated weight for the other queues is
increased by their respective weight increments.
