If you want UPLNK to be the max then children need UPLINK/4 - the parent
will not cap it. Use ceil UPLINK aswell if you want each to be able to
reach max when other classes are empty.>

This is strange, not sure if it''s what you want - you don''t
need another
htb here, though it is possible it''s not normal. If you just want a
child under 1:10 then do as you do below with parent 1:10, but remember
parents don''t cap rate of children.

If you really want htb under htb then classid 10:11 may work.
