[c-nsp] BW allocation

[ambedkar]

hi,
i am using vsat link of 256kbps, two channels of 100kbps and 156 kbps 
each. i am using cisco 3845 router. here i want to restrict the second 
channel to 156 kbps.

I have an idea about class-map,policy map and service policy.

i tested with the class-map. have a look at it.

class-map match-all TEST
match input-interface gig 0/0.11 (sub-interface which is of 156kbps)

but the problem is it is taking as a global interface i.e., gig0/0 
instead of sub-interface i.e., gig0/0.11.

And also want to know in policy map, what is the difference between 
bandwidth and police.

thanks in advance.
bye.
