Hi Bert Hubert, > I received one report of it not working as expected. I studied the code, and > it looks sound. So Junus, give it a try and let us know if it works! The > HOWTO mentions how to configure this tri-band fifo. Where is the location of exampe how to using prio qdisc? I can't find the example of prior qdisc at Linux advanced Networking HowTo. When I looked at section 9.1 "pfifo_fast" and 14.4. "Prioritizing interactive traffic", they never give an example how to using it. Now I am still learning the source code sch_prio.c, maybe it will be help. Regards, Junus Junarto D
