Which AOS-CX switches support weighted fair queuing (WFQ)?
Which AOS-CX switches support weighted fair queuing (WFQ)?
AOS-CX switches that support weighted fair queuing (WFQ) is the 8400 model. The 8400 switch specifically has the capability to utilize WFQ, which is not supported by the other models such as 8320, 8325, 6300, and 6400. Those other switches may support other queuing mechanisms like deficit weighted round robin (DWRR), but not WFQ.

Correct Answer: C
A: 8320 and 8325 both support WFQ
Selected Answer: A , Only 8320 and 8325 this is from 8400 Data sheet: Quality of Service (QoS) • Strict priority (SP) queuing and Deficit Weighted Round Robin (DWRR)
The factory default profile has eight queues, numbered 0-7. For each queue, you specify a scheduling algorithm and settings associated with that algorithm. All the AOS-CX switch models support strict priority (SP) for the algorithm. In addition, the 8325, 8320, 6400, and 6300 support deficit weighted round robin (DWRR) while the 8400 supports weighted fair queuing (WFQ).
