Hi,

I have 7600 router with RSP720 and i need to configure Netflow export to external server. Do i have to configure NDE as well?

Thanks

Hello,

or contact me directly. Configuration is really easy.

Hi Rojer,

If you plan to export NetFlow statistics, globally enable NDE on the router the you can configure like below....

#ip flow-export destination
#ip flow-export version
#mls nde sender version

And enable NetFlow on individual interfaces which are you want by issuing the following commands:

#interface
#ip flow ingress

(Optional) To configure NetFlow sampling, do the following:

Enable sampled NetFlow globally on the router (mls sampling).
Enable sampled NetFlow on individual interfaces (mls netflow sampling).

Verify the NDE configuration to ensure that it does not conflict with other features such as QoS or multicast. Use the show ip interface command to verify the configuration.

Please rate if this helped you...

Hi Naidu,

As mentioned, you mean i have to configure NDE everytime i enable Netflow? Anyway, as Jan posted, no need to configure NDE.

Thanks

Hi,

What do you mean "i have to configure NDE everytime i enable Netflow"

That is a global configuration command not a interface command, so it is onetime configuration...

Hope this clear you...

Hi Naidu,

If i configure just as command below, is it enough to get flow statistics? or i need to use NDE command as well.

router(config)# ip flow-export version 5
router(config)# ip flow-export destination  2000
router(config)# ip flow-export source FastEthernet0
router(config-if)# ip flow ingress

Thanks

Hi,

Yes, that looks fine...

Just configure like that and see if you are getting any netflow stats by giving command Router#sh ip flow export & Router#sh ip flow interface & Router#sh ip cache flow

If you are not getting any stats then you need to configure NDE like belwo...

Router#mls nde sender version

Please rate if this helped you...
