Hi everybody sorry for my poor=20 english.

My script doesn't work very = well

I want to share bandwidth between 3 = subnet (64k,=20 128k, 256k)

if i put the flag bounded on the class = root that's=20 doesn't work bandwidth is not limited

if i put the flag bounded on each = class, all the=20 subnet is limited by each rule:

subnet 64 can't use more than a = total of 64k=20 as it was 1 single user

...

so i don't know how to share 64k by = user on subnet=20 64, 128k by user on subnet 128, 256k by user on subnet 254.

What's wrong with my = script?

thx a lot.

Michael
