CA not able to get NetFlow from router

[Gurdev Singh]

Hello,

We have approx 300+ cisco routers in our network and for a couple of them the data is not pulled on ca NetFlow, and the interface data is also not shown in CA PC.

We removed and re-added the netflow configs on the router but the issue remains the same.

When in CAPC I go in the menu > Group > Group settings > NFA > Router Groups, there the router is is not populated in any of the 2 harvesters.

Thanks,

Hi Gurdev

I suggest verifying the flows are arriving at the harvester using wireshark or packetmon. It is possible a firewall rule is blocking the flow.

Hope that helps.

Have you verified that you have the correct Community string configured in those routers?

Without the ability to poll the device via SNMP the flow data may be ignored.

Hi

Can explore below links which has additional information to earlier suggestions

How can I determine if a NetFlow enabled device is sending the correct fields and data using WireShark?

Why does my NFA stop displaying data for a router if it cannot be SNMP polled?
