Four type of WFQ :
- Flow-based WFQ
- Flow-based Distributed WFQ (DWFQ)
- Class-based WFQ
- Class-based Distributed WFQ

Distributed just run on versatile interface processor (VIP) for faster performance and a route switch processor (RSP).

Example simple implement WFQ :

#config interface to WFQ

(config-if) fair-queue

#verify

show interface INT
...
