I think you can apply CBWFQ to a sub Ethernet interface if you configure
Traffic Shaping in a hierarchical Policy,

You can't apply CBWFQ where the interface bandwidth is unknown eg to an
ATM PVC under a PVP where the PVP speed is configured, as the PVC is then
not able to be configured with a speed (bandwidth considered 0 or unknown).
Also it can't be applied to Ethernet subinterfaces as they don't have
a true "bandwidth" dedicated to them - it must be applied on the full
interface.
Further, you can only reserve up to 75 percent of the bandwidth of an
interface, although you can override that by setting an explicit
max-reservable-bandwidth.
David.
