What would be nice is if you could document what happens when a) child ceil > parent ceil b) child rate > parent ceil c) child ceil > parent rate d) child rate > parent rate How does this influence the shaping results and the shaping of other classes? I've actually asked a similar question before: If you have 1:1 / \ / \ 1:2 1:3 /|\ \------ / | \ \ \ 1:4 1:5 1:6 1:7 1:8 if 1:7 and 1:8 respects the rate/ceil of 1:3 and 1:3 respects the rate/ceil of 1:1, but 1:4 does not respect the rate/ceil of 1:2 and 1:2 respects the rate/ceil of 1:1, does the shaping of 1:3 work as normal and only those classes under 1:2 are adversely affected or not? from your previous answer, it seems that the classes under 1:3 would not be affected, but I would love to know why. what happens with 1:4 requests some bandwidth which 1:2 does not have... --=20 Regards Abraham NEWARK has been REZONED!!
