Hi all, the LC on 12000 series is 12000-SIP-601 (engine 5) with multiple ST=
M-1 SPA card. As far as I know the engine 5 card cannot do 450Kpps on netfl=
ow. Since the STM-1 is mainly for NB-AMR traffic (95%), do you recommend th=
e sampled netflow instead? Does anyone aware of the sampled netflow accurac=
y?

Just a quick note..
You may want to post the Line Cards they have...Distinct LC have distinct N=
etflow capabilities (and impact).
