Dear all, I am starting with Linux Qos mechanism. I believe that for my needs the two Qdiscs: - PRIO - pfifo_fast are enough. In fact I am trying to set up a simple Linux-box 1Lan-1Wan able to distinguish and give priority to VoIP traffic against IP BE traffic on WAN interface. Yet I cannot find any examples concerning these Qdisc (for pfifo_fast I cannot even find manpages) . May you help me ? Thanks in advance for your support.

It may be worthwhile to add to FAQ that if you have a cbq or some other queuing discipline attached to the network device, and you want to go back to pfifo_fast qdisc, you can achieve this by simply deleting the current qdisc. Then pfifo_fast falls just in place. I don''t know whether this is the right way, but it works for me, and since it is linux, this makes it the right way ;-) Kind regards, -- Vik
