Hello,
I'd like to configure CBWFQ over FR as below, one subinterface is for TCP user and another is for voice user.
Does subinterfaces inherently support CBWFQ?
class-map match-all TCP
match access-group 103
class-map match-all VOICE
match access-group 102
!
policy-map CBWFQ
class VOICE
bandwidth percent 45
class TCP
bandwidth percent 30
class class-default
fair-queue
!
interface Serial0/0
no ip address
encapsulation frame-relay
service-policy out CBWFQ
!
interface Serial0/0.1 point-to-point
ip address 192.168.10.1 255.255.255.0
frame-relay interface-dlci 400
!
interface Serial0/0.2 point-to-point
ip address 192.168.11.1 255.255.255.0
frame-relay interface-dlci 500
Thanks

Hello,
no, the policy is not inherited on the subinterfaces. For your configuration to work, you need to apply the following:
class-map match-all TCP
match access-group 103
class-map match-all VOICE
match access-group 102
!
policy-map CBWFQ
class VOICE
bandwidth percent 45
class TCP
bandwidth percent 30
class class-default
fair-queue
!
interface Serial0/0
no ip address
encapsulation frame-relay
--> frame-relay traffic-shaping
!
interface Serial0/0.1 point-to-point
ip address 192.168.10.1 255.255.255.0
frame-relay interface-dlci 400
--> class DLCI_400
!
interface Serial0/0.2 point-to-point
ip address 192.168.11.1 255.255.255.0
frame-relay interface-dlci 500
--> class DLCI_500
--> map-class frame-relay DLCI_400
service-policy output CBWFQ
--> map-class frame-relay DLCI_500
service-policy output CBWFQ
Watch out though, once you have enabled Frame Relay Traffic Shaping on your main interface, all the DLCI configured on the subinterfaces will default to 56000kbps. If, and that is likely, that is not what your DLCIs actually have available as bandwidth, configure the cir and bc/be values in the frame relay classes as well...
Let me know if you have problems with this.

Check this link out. It replaces the legacy FRTS with MQC based commands. So ur restriction of 56K per PVC is removed in this.

Hi GP/THT
thanks for answering, I knew CBWFQ for every logical interface is shape function need first,,,
what i am asking is somehow i should apply CBWFQ on main interface with ip addess based classes, and some cisco document saying that it works like single pipe, because subinterface is just logical interface.
configuration is more like this
class-map match-all TCP
match access-group 103
class-map match-all VOICE
match access-group 102
!
policy-map CBWFQ
class VOICE
bandwidth percent 45
class TCP
bandwidth percent 30
class class-default
fair-queue
!
interface Serial0/0
no ip address
encapsulation frame-relay
service-policy out CBWFQ
!
interface Serial0/0.1 point-to-point
ip address 192.168.10.1 255.255.255.0
frame-relay interface-dlci 400
!
interface Serial0/0.2 point-to-point
ip address 192.168.11.1 255.255.255.0
frame-relay interface-dlci 500
access-list 102 permit ip any 192.168.11.1 0.0.0.255
access-list 103 permit ip any 192.168.10.1 0.0.0.255
Had anybody been through before?
Thanks

Iam not sure this will work. But i was going through some document on using PVC bundles and mapping to IP QoS etc. It didnt make much of sense to me. Hope it helps you.
