end Cisco routers support router-based netflow aggregation to reduce export data volume and improve scalability. Does cflowd support all these aggregations?
More detail from Cisco available at http://www.cisco.com/warp/public/cc/pd/iosw/ioft/neflct/tech/napps_wp.htm. (as of Aug 2000). The five Cisco aggregation schemes allow summarization of data on the router before export. In fact, Ciscos will support multiple netflow `aggregation caches’. The normal flow ager process runs on each active aggregation cache the same way it runs on the main cache. On-demand aging is also supported. NetFlow v8 aggregation is available on all Cisco netflow-supported platforms beginning in 12.0(3)T and 12.0(3)S. Default secondary NetFlow v8 aggregation cache size is 4096 entries on all platforms that support Cisco IOS NetFlow. Note that traditional v1/v5 aggregation netflow services may be enabled simultaneously, but only the router-based aggregation feature uses v8 export format.
