NetFlow - Meraki MX100


What needs to be tweaked to get NetFlow working on a Meraki MX100?  The NetFlow v9 Template is failing due to missing fields.  Both MX100 and LogicMonitor Collector are running the latest code.  I have NetFlow running successfully on many ASA's so I am familiar with the overall NetFlow requirements.

Thanks in-advance for any assistance!

Hi Todd,

My understanding is that Meraki is providing NetFlow data in a non-standard format that many monitoring tools have trouble with, due to the Meraki-specific implementation of NetFlow.

There is a little more information to be had regarding the situation - as covered here: https://www.plixer.com/blog/netflow-reporting-2/meraki-netflow-support/ :

"NOTE: The Meraki documentation states that “The MX and Z1 do not support exporting an SNMP ingress or egress interface index via NetFlow.” This means that some NetFlow Analyzers will not be able to report on the export."

This is (unfortunately) not the first time we've run into this issue, and the most effective thing we can do at this point is to encourage Meraki to fix their NetFlow implementation - by having customers provide them with direct feedback - which can be done through the Meraki interface: https://meraki.cisco.com/blog/2014/07/make-a-wish-2-0/
