It depends on how many active flows you have at any one time. Also, I
don't think the SIP-601 supports full netflow V5 in hardware, only V8,
which is aggregated netflow, which may not be what you want. It does
do V5/V9 sampled netflow in hardware. The sampled netflow on that
platform is better than on say the 6500/7600, so I would just go with
that.

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

Hi all, I have a customer who has a MPLS network for E/// Media
Gateway (MGW) NB-AMR VoIP traffic. The packet size for the NB-AMR
traffic is fixed size 110 bytes. During the high load period, it
can reaches 450Kpps on a STM-1 link. The router platform is Cisco
12000 series, can the router generate 100% netflow data with such
traffic load? Also can someone suggest a carrier class netflow
collector for mobile service provider environment.
Just a quick note..
You may want to post the Line Cards they have...Distinct LC have
distinct Netflow capabilities (and impact).
