bandwidth command for subinterfaces with shaping

[tholawrence]

Does anyone know why the bandwidth statement on the subinterface would be ignored unless its applied to the main interface? In a head-end setup i may have additional subs and I would think the bandwitch statement on the main int should reflect the actual bandwidth while the subs woudl reflect their individual allocation.. Config:

policy-map main-policy
class voice-class-map
  bandwidth percent 20
class video-class-map
  bandwidth percent 30
class management-class-map
  bandwidth percent 5
class critical-class-map
  bandwidth percent 25
  queue-limit 1024 packets
  random-detect
class class-default
  bandwidth percent 5
  queue-limit 1024 packets
  random-detect
policy-map traffic-shape-policy
class class-default
  shape average percent 90
  service-policy main-policy
!
int gi0/0
desc WAN
speed 100
duplex full
bandwidth 50000
!
int gi0/0.100
encap dot1q 100
ip 1.1.1.1 255.255.255.0
service-policy out traffic-shape-policy
bandwidth 50000

Thanks!

To configure bandwidth to be used as a reference for calculating rates of quality of service (QoS) percent configurations on a physical or logical interface, use the bandwidth qos-reference command in interface configuration or subinterface configuration mode.
