Hi,
I would like to have more information about NetFlow and OpenFlow application on Nexus 31108PC-V platform.
In my scenario I have a Nexus 31108PC-V with release 7.0(3)I4(3) and base license, I can see the feature NetFlow in "show feature" output:
SW-N3K-2# show feature
Feature Name Instance State
-------------------- -------- --------
netflow 1 disabled
but I can't enable it bicause in configuration mode this feature is not available:
SW-N3K-2(config)# feature n?
ntp Enable/Disable NTP
nv Enable/Disable VxLAN
nxapi Enable/Disable nxapi
Instead, OpenFlow seems a feature not available.
Could be a license restriction?If yes, which license is needed? What else?
Thanks in advance.
Best regard
Gian Luca

Hi Peter,
I know that NetFlow and OpenFlow are two different feature and there aren't relation between the two.
If is better I open a discussion dedicated to OpenFlow.
Thanks

Hello Gian Luca,
Unfortunately, the 31108PCV switch does not support NetFlow. The fact you saw the NetFlow feature printed out in the show feature is in fact a cosmetic defect only; that feature should not have been listed there at all. The 7.0(3)I7(5) does not report this feature anymore:
N3K2(config)# show ver | i NXOS|Chassis NXOS: version 7.0(3)I7(5) NXOS image file is: bootflash:///nxos.7.0.3.I7.5.bin NXOS compile time: 8/28/2018 2:00:00 [08/28/2018 09:51:46] cisco Nexus 31108PCV Chassis (Nexus 9000 Series) N3K2(config)# show feature | i flow openflow 1 disabled sflow 1 enabled N3K2(config)# feature n? nat Enable/Disable NAT netconf Enable/Disable netconf Services ngoam Enable/Disable ngoam ntp Enable/Disable NTP nv Enable/Disable VxLAN nxapi Enable/Disable nxapi nxsdk Enable/Disable nxsdk Services
I am sorry to disappoint you; you will not be able to start NetFlow on this platform (in fact, no N3K platform currently supports it).
OpenFlow is an entirely different and unrelated mechanism; it is not used for traffic statistics collection but rather to control traffic forwarding entries in the hardware. We should not talk about OpenFlow in relation to NetFlow at all; these two are entirely different things.
Best regards,
Peter

Hello Gian Luca,
My apologies - since you have been talking about the two unrelated features in the same thread, and did not really clarify what exactly are you focusing on with the OpenFlow, I was not sure if you were confusing the two. I apologize - I meant no offense.
Maybe it would be better to open another thread just for the OpenFlow issue you are looking at.
Thank you!
Best regards,
Peter
