Using Netflow v9 in a Active/Active cluster

[rkra]

I configured a Netflow profile and associated it with a "Untrust" Interface on my active Machine in my setup.

I was surprised seeing that the second Active machine got this assotiation too. So I accume both machines are sending to the same receiver and to the same port.

I'm new to Netflow and my question is: How does the receiver distinguish which data is coming from which server?

Both IFs are sending to UDP 2055.

Do I have to send each Flow to a different port on the Flow-Receiver?

Hi RKRa,

In Active/Active set up both box remains active. One is Active-Primary and other is Active-Secondary. Data Interface for bot boxes processes traffic.

Hence if anything is configured on those interfaces its active for both the devices.

However, Newflow source traffic should be different for both the box. I think you can distinguish based on source IP.
