The trick is that "logical" interface has no actual state of congestion -
hence
any bandwith reservation by itself is useless. You need to introduce
artifical
congestion with shaping (MQC or FRTS) and apply CBWFQ as second-level
policy.
One special exeption is MLP bundle interface. it does support CBWFQ
*directly*,
in order to permit LLQ and enable voice packets interleaving.
