Flexible Netflow multiple exporters

mpidoux_upc
Level 1
Level 1

Hello everyone,

 

I configured Flexible Netflow on a Cisco ASR-920-4SZ-A, with IOS asr920-universalk9_npe.03.18.03.SP.156-2.SP3

The first exporter is working well but the second one is not working, no data sent.

If I remove the first exporter, it's working well. Netflow monitoring server is working well, it receives data from another interface.

Is there something wrong in my configuration ? Is it normal or a bug ? I read in the official doc it was possible to configure multiple exporters.

I would try to configure exporters with different configurations. For example, use different ports and source-interfaces (maybe loopback ones).

Give it a try.

Still the same result, no data sent to the client.
