[c-nsp] Need working ASR1k pppoe police/shaping

[Mike]

Hi,

     I am trying to determine a basic configuration for my Asr1k that 
will allow me to establish some basic policing / shaping for my PPPoE 
subscribers. I have read a lot of the cisco ISG documents and frankly 
don't understand any of them; there isn't a clear explanation of the 
interrelationships between policiy maps, class maps, control classes and 
all the other numerous moving parts that all have to work in order for 
any of it to work. No other 'examples' I have encountered online work 
either, they all barf with various errors or simply fail to engage for 
silent unexplained reasons. I have asked here a few times generally and 
have not gotten a working solution. I still need some help!

     I have radius and am terminating pppoe sessions. On my c7201, I am 
using CAR from radius to establish basic bandwidth limits per subscriber 
(for those who need it set at the bras end, where their own cpe isn't 
doing it for them), and this works well. I can connect via pppoe on 
1gbps ethernet and have the radius attributes set so that the pppoe 
session is limited to 10mbps down / 1mbps up and it works flawlessly, 
and is quit easy to understand and use.

     I would like to be able to replicate these results on ASR1k 
initially where the rate limits are being established in radius only and 
the ASR just polices the pppoe session. As a future stretch goal, I'd 
also like to be able to do finer grained QoS and help my end users make 
better use of their pipe.

     Does anyone have a pointer to any examples for either or both of 
these that work on ASR1k on the IOS-XE 3.10.xx?

Mike-
