[j-nsp] NetFlow on M7i

[Erdem Sener]

 Hi,

   No, not all the M7i's come with an integrated ASM (Adaptive
Services Module). Some are bundled with on board GE interface, some
are bundled with ASM and some are 'plain', so to speak.

 You can check which one you're logged in with 'show chassis hardware'
and see what you have on FPC1 PIC 2.

 You can technically do sampling without a services pic but in this
case you'll not risk running into performance issues (based on your
volume, how busy is your RE without sampling etc.) but you may hit the
PFE problem described on PSN-2007-02-026, if you're using a older code
(in terms of build date)

 Cheers,
 Erdem
