At NASA, we take full netflow from ASR1000s with 5Gbps active on 10Gbps links.. No problem.
Up to 300 flows/sec (with much higher peaks) which may be lower than you as we have long running FTP downloads of environmental science data. We collect with the open-source SiLK software, and use FlowViewer for a web front end. All kinds of value.

We use ME3600's for L3VPN tails only (As they unfortunately do not support Netflow). After suggestions on an upgrade path from 1G -> 10Gb+ - We can do mulitple 1Gb links between POP's, and ME3600->ASR1K(For VRF/VPLS traffic), but it seems more like a bandaid solution, and we are limited at some POP's with port density (i.e. ASR1001's). Do we stick with ASR1K's, but larger ones (1004, 1006), so we can install single port 10Gb SPA's...or something else that supports Netflow, but higher density 10Gb...or bandaid (Multiple 1Gb ports) until we no longer "require" Netflow for billing...If netflow wasnt in the equation, what platform would be recommended for 10Gb+ "Core" (i.e. push the ASR1K's out to IPTransit/Peering, ME's for L3/L2 termination(PE), but what for the "core"(P)? Thanks in advance for any suggestions. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
