Netflow Version 5 is the most popular and one of the simplest versions of netflow to enable. Its popular due to its almost ubiquitous support on Cisco routers as well as the fact that it is also the most efficient in terms of bandwidth usage.
To enable netflow you must first enable the global set of commands
- ip flow-export destination ip_address 2055
- ip flow-export source interface
- ip flow-export version 5 [peer-as | origin-as]
- ip flow-cache timeout active 1
- ip flow-cache timeout inactive 15
- snmp-server ifindex persist
Then enable netflow on each interface you wish to monitor
