What Is New

•
The NetFlow Data Export Version 9 is an enhancement to support different technologies such as Multicast, Internet Protocol Security (IPSec), and Multi Protocol Label Switching (MPLS).

•
Users can define aggregation schemes by choosing keys and values. The key fields form a unique key for output file records. The value fields for records with the same unique key are aggregated.

CNS NetFlow Collection Engine, Release 4.0 can be deployed on a Linux platform using RedHat Linux 7.1 for i386 processors.

Note
CNS NetFlow Collection Engine, Release 4.0 requires at least 45 MB of disk space for its binary and configuration files.
CNS NetFlow Collection Engine generates output files containing aggregated data. These files require additional disk space; the exact amount depends on the flow arrival rate, collection interval, number of aggregation schemes specified, binary versus ASCII data file types, use of compression or not, and data file retention policies.
For more information on planning and managing disk space usage, see the section about Managing Disk Space in Chapter 5 of the Cisco CNS NetFlow Collection Engine Installation and User's Guide.
