80-Series QoS

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. 

This section contains the following information and procedures:

WFQ is the default queue-servicing algorithm. When a port is set to use the 
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.
