Good point.
Bringing in the frame relay encapsulation; up until 12.2(13)T it was
necessary to configure frame-relay traffic shaping in a class map for
MQC to take effect and for the show policy-map interface command to show
anything. This is no longer the case. You can do the same trick with
shaping as decribed below to configure MQC on a per sub-interface (so in
the case of a p2p interface, this is per DLCI) basis for frame relay
too.

We are not allowed to do queuing on a Subinterface, but we can shape on
a Subinterface/ so doing nested CBWFQ Policies to cheat requirements.
class-map match-all Trafico_VOZ
match access-group 100
policy-map HIJA
class Trafico_VOZ
priority 12
on sub int we are not allowed to apply it so we create another policy
name parent policy-map PAPA
class class-default
shape average 1000000
service-policy HIJA
interface Ethernet0/0.50
encapsulation dot1Q 50
ip address X.X.X.X
service-policy output PAPA
