[c-nsp] cisco maximum rate-limit interfaces

[Mike]

Hi,

I have a 7201 running c7200p-advipservicesk9-mz.122-33.SRD8.bin, 
configured as a bras (pppoe). I have about 1000 simultaneous pppoe 
sessions at the moment, and most subscribers are rate-limited by their 
cpe devices (under our administrative control). There are some 
subscribers, however, which we instead use a radius profile and cisco 
avpairs to apply rate limits (ala "Cisco-AVPair += 
lcp:interface-config=rate-limit input 1000000 1100000 1300000 
conform-action transmit exceed-action drop" for example) to their 
interface when it comes up. This works well, but I'm trying to figure 
out if there is a maximum or realistic number of these I can have at any 
one time and whether there are any tradeoffs or caveats to be aware of 
if scaling this up to many hundreds or more of users?

Thanks.

Mike-
