Netflow Nexus 7000

Hi all,

A few months ago I have configured netflow on a Nexus 7000 with NX-OS version 6.0.2.

This was my config:

flow exporter Fluke_NetflowTracker

  description export netflow to Fluke_NetflowTracker

  destination x.x.x.x use-vrf management

  transport udp 2055

  source mgmt0

  version 9

flow exporter Fluke_Optiview

  description export netflow to Fluke_Optiview

  destination x.x.x.x  transport udp 2055

  source Vlanx

  version 9

flow monitor MonitorTrafficToFluke

  record netflow-original

  exporter Fluke_NetflowTracker

  exporter Fluke_Optiview

This flow was activated on some SVI's. "ip flow monitor MonitorTrafficToFluke input"

Recently we have upgraded the NX-OS to version 6.1.3. The netflow keeps on working, but the syntax of the netflow configuration has changed. Now you have to add a sampler as well.

So I have created the following sampler.

sampler NetFlow-Sampler
  description Netflow Sampler
  mode 1 out-of 1000

When I want to update the current configuration with the sampler I can't adapt or remove the existing netflow configuration on the SVI.

NK7(config-if)# no ip flow monitor MonitorTrafficToFluke input
ERROR: A sampler must be configured for an interface on an F2 card

NK7(config-if)# ip flow monitor MonitorTrafficToFluke input sampler NetFlow-Sampler
An additional 1:100 sampler, over the configured sampler is applicable for F2 ports
Error: Sampler can not be changed on Interface Vlanx. Remove flow monitor first.
ERROR: Command has failed

How do I update or remove the existing configuration on the SVI.

I want the config to be "ip flow monitor MonitorTrafficToFluke input sampler NetFlow-Sampler"

Thank you,

Best Regards,

Joris

Hi Joris,

Try no feature netflow under the interface and try to re-apply the whole configs. Since its a F2 we dont support config changes until 6.2(2) only way is to remove the configs using no feature netflow and re-applying it.

Thanks,

Richard.

Hi Richard,

Disabling the netflow feature does the trick.After re-enabling it I can use the new syntax.

Thanks for you feedback.

Best Regards,

Joris
