Jody: I don't know if you answer basic HTB questions but I'l try anyway. I'm implementing AF and EF with a root rate of 500 kbps (kilo bits per second). I am using DSMARK to classify packets. I'm implementing this on two different hardware sets PPC and x86 with the same kernel options configured. Problem: My root rate is going about 75 kbps over its 500kbps limit (ceil 500). I believe this is because of burst and cburst settings. I am using default calculations now, on all classes. Is there a formula to use in tweaking these values? I would like my rates to follow the assigned rate more closely. I am generating traffic with a hardware traffic generator. Starting at 300 kbps stepping by 100 kbps up to 1mbps. Each step lasts for 60 sec. My config script is attached. Thanks. Jon <<diffserv9-26-gred>> Jon Flechsenhaar Boeing WNW Team Network Services (714)-762-1231 202-E7
