Class based shaping Query

Hi All,

I read in some of the documentation ,that it is not possible to configure CB
shaping on per DLCI basis when the Frame-Relay interface is multipoint
subinterface with more than one DLCI.You can only apply CB shaping on the
sub-interface and cumulatively shape traffic for all DLCI's on the
sub-interface.

You will have to use FRTS in this scenario if you need per DLCI shaping.

But when I tried to lab it up,I was able to configure per DLCI CB shaping
with FR multipoint interface.Could you please confirm if there are any
latest changes in support of this feature.

Here are the configurations....

*interface Serial0/0/0
 no ip address
 encapsulation frame-relay
 clock rate 2000000
!
interface Serial0/0/0.125 multipoint
 ip address 155.1.155.2 255.255.255.0
 frame-relay interface-dlci 201
  class test1
 frame-relay interface-dlci 202
  class test2*

*map-class frame-relay test1
 service-policy output shape
!
map-class frame-relay test2
 service-policy output shape*

*policy-map shape
 class class-default
