Hi,
I have to put differnet QOS policies on 2 sub interfaces of my 7204 router, but I am getting the following message when applying,
TEST(config)#int pos4/0.72
TEST(config-subif)#service-policy output MPLS-Link
CBWFQ : Not supported on subinterfaces
TEST(config-subif)#
Please sugust how to solve this issue,
Regards,

Ok, the map-class issue took us off-track and your problem is that you didn't change the config as I recommended back on my first post on February 6th.
You must configure a hierarchical policy with the shape command at the parent level. Use the bandwidth command for CBWFQ, or the priority command for Low Latency Queueing (LLQ) at lower levels.
Here is sample config that works
policy-map MPLS-Link
class VOIP
priority 10000
set dscp af31
class class-default
fair-queue
random-detect
!
!
!
policy-map MPLS-Sub
class class-default
shape average percent 75
service-policy MPLS-Link
On the subinterface, remove the map-class and apply service-policy output MPLS-Sub

Posting the MQC configuration will sure help.

Hi, read:

Hope this helps, please rate post if it does!

HI Mohammed, [Pls RATE if HELPS]
Normally, the CBWFQ is not supported in Sub-interfaces of CISCO.
Create a Policy-map as Parent & match only "class class-default" in the Parent Policy-map. Then apply the "service-policy output MPLS-Link" inside the Parent Policy-map.
Finally, apply the "Parent" policy-map to the sub - Interface.
It should work....

Let's see map-class frame-relay frclass portion of the config.

HI Mohammed, [Pls Rate if HELPS]
Interface B/W of POS4/0.72 is only 155000
The requested B/W for class VOIP is 10000Kbps.
It means out of B/W=155000, only 28Kbps is left Un-used. Refer is there any Class map already using the more Bandwidth of the Interaface.
Refer: "map-class frame-relay frclass" and show the configuration.

You are missing the map-class from the post. This may be influencing your available bandwidth on the interface.
I don't recommend applying a service-policy on the interface along with a map-class. You should add the service-policy under the map-class as a child policy and apply the map-class on the interface.
HTH,

I have took off the service policy from the interface and applied on sub interface and getting the error when assiging policy to map-class,

And we are still unable to see what's contained on the map-class.
The reason you haven't post it is due to confidential information (not sure how confidential can be a map-class) or you aren't understanding what I am asking for?
I also don't know what other interfaces are under POS4/0 as they also consume the allocated bandwidth. The bandwidth is assigned to the main physical interface, not the subinterfaces.

hi,
The resason you cant see anything in map-class cos,at present nothing contained in map-class, cos as soon as I try to attach service-policy in class-map it trough error message and does not attach service-plicy to frame- class as below,
conf t
TEST(CONFIG)# map-class frame-relay frclass
service-policy output MPLS-Link
"Error"
I/f POS4/0.72 DLCI 16 class VOIP requested bandwidth 10000 (kbps), available only 28 (kbps) ,
I have moved the b/w command from subint, I have 2 subint under physical pos4/0.

Hi,
This router has not been connected to network yet, I am middle of building it, so output of these commands does not show much.
