[c-nsp] c7200 - QoS on ATM subinterfaces/PVCs

I'm tryin to configure QoS (PQ and shaping) on ATM PVC.
te09186a00800d76b5.shtml) says configuration is pretty straightforward.
Below is sample configration from CCO, in my case situation is about the
same, only thing that differs is 'priority xxx' instead of 'bandwidth
bandwidth percent 60
bandwidth percent 20
shape average 10240000 40960 40960
interface ATM5/0/0.1 point-to-point
vbr-nrt 50000 50000 94
service-policy output parent
class-map match-all 3
match ip dscp af31
match ip dscp af32
match ip dscp af33
class-map match-all 5
match ip dscp ef
shape average 512000
If I try to apply service-policy AAA to some PVC (not subinterface), and
immediately after that try to look at subinterface configuration ("do
show runn int atm2/0.134) - service-policy command is there (under 'pvc'
statement), like below:
interface ATM2/0.134 point-to-point
ip address 188.8.131.52 184.108.40.206
atm route-bridged ip
pvc zzz 4/44
service-policy output AAA
, but as I exit PVC configuration mode - following string appear at
logging buffer - "GTS : Not supported over ATM VCs", and there are no
service-policy like commands at subinterface configuration.
What's a bit interesting - if I try to configure same policy-map for
both - output and input, at first box says "GTS : Can be enabled as an
output feature only", what I believe means that GTS can't be enabled for
input (that's OK), but it should be supported as output feature, but
next string says the same as before - "GTS : Not supported over ATM VC".
Here comes question - is it supported or not? And if it is - how to
configure it correctly? Maybe it's not supported if PVC is UBR and I
should configure some VBR cell rates?
Box is c7206-VXR running 12.3(2)T2 code.
