Hello again, Thank you for you help last time. I try to create final check for htb, and found some problem. Can you give a quick fix for the problem? 1:1 (ceil 1500kbps) / \ (ceil 800kbps) 1:2 1:8 (ceil 700kbps) / \ \ 1:4 1:12 1:14 / \ (prio 0) 1:10 1:11 (prio 1) The tree under 1:2 is almost the same as you example and is working. And I try to build a larger tree (4 levels) and I would like to do following: class 1:14 is completed isolated even no traffic, the BW will not borow. class 1:12 is empty all the time. class 1:10 is prio 0 and class 1:11 is prio 1 1. My understanding is 1:8 and 1:2 are isolated because of ceil and will not borrow? 2. Since 1:12 is always emppty, it can borrow the excess to tree 1:4 and 1:10 will get all the BW. But in my case, the prio parameter seems to be not very ok. It will give BW to both 1:10 and 1:11. My HTB: echo "sim7 can do the priority BW" echo Clean all the tc setup ./tc qdisc del dev lo root ./tc qdisc add dev lo root handle 1: htb default 12 ./tc class add dev lo parent 1: classid 1:1 htb
