1] I see that you have mixed "bandwidth" and "bandwidth remaining percent / bandwidth percent" . You cannot configure this together in same policy. It will give you an error.

2] Is this configuration going to be on sub-interface ?

[Vinayaka Raman]

1) I want assure 18 meg to cm_af4x..Is there any other way of doing it?

2) No..it will be applied over physcal interface

[Nandan Mathure]

1] You can you policing there as there is not option or you can calculate all the "remaining percentages" and convert them for "bandwidth" only command set.

2] CBWQ is not supported on subinterfaces , Only shaping is supported on the subinterfaces. So class-map with class-default is necessary as all it does is tricks the router that its actually just using shapping.

E.G.

policy-map PARENT

class class-default

shape average 100

service-policy pmmpls5

Shaping to 100% percent means traffic is sent as is.

*EDIT*

I see that you changed it to physical interface.

So no need for another class-default class map.

Yes and no.  You always have a default class, even if you don't explicitly define it.

Since you match "everything" in cm_af2x you would think nothing would fall into class-default, but you didn't really match everything, you only matched any IP.
