Does MikroTik RouterOs support Netflow ? If it does how do I enable it ?
Thanks for any help

If it only works with Cisco IOS products then no.. but if it collects data via SNMP, I don’t see why it wouldn’t..

We have Traffic-Flow which is totally compatible with cisco’s Netflow.

Traffic-Flow is very similar to Cisco’s Net-Flow, you can read about it here:

http://www.cisco.com/warp/public/cc/pd/iosw/ioft/neflct/tech/napps_wp.htm
http://www.cisco.com/warp/public/732/Tech/nmp/netflow/index.shtml

Configuration is like this:

/ip traffic-flow - general configuration

enabled=yes/no

interfaces= all, or interface list

traffic flow will only work with the data that comes through the specified
interaces

cache-entries=1k - 512k - how many flows you will have at the same time

the following parameters identiry an unique flow:
source ip, destination ip, in interface, out interface, source port,
destination port, ip protocol.

active-flow-timeout= maximum lifetime of flow

inactive-flow-timeout= after there is no traffic, how much time will pass
until the flow will be counted as stopped


/ip traffic-flow target - where to send information about flows

address:port - where to send UDP packets
version - 1, 5 or 9 according to Cisco Netflow version

all these parameters are the same as in Netflow, you can read in the above cisco links or in RFC3954

Normis,
Thanks for the quick reply. Iam unable to get to those links as it needs additional access login. Any other way I can access those pages ?

Does traffic-flow come with mikrotik os ? or do I need anything additional ? And what would be the cpu/memory overhead on enabling this in my pc ?

Thanks

I can access both pages without any logins.
