3750X netflow configuration.

Hello Nicos,

Does your 3750x has the C3KX-SM-10G module?  I believe you need it to export flows.

When I checked the guide for NetFlow on 3750 I found this note

Flexible NetFlow is supported only on the Catalyst 3750-X and 3560-X switch running the IP base or IP services feature set and equipped with the network services module. It is not supported on switches running the NPE or the LAN base image.

So from an IOS perspective you are fine and should not need to upgrade your IOS. I am not clear whether your 3750 has the network services module that they describe.

Here is the link that I was using if you want to check it further

3750X netflow configuration.

OK, it seems that i need the C3KX-SM-10G module instead of the C3KX-NM-10G i currently have.

3750X netflow configuration.

I would advise that even with that module, trying to get useful Netflow data on a L3 switch is often an unsatisfying endeavor. There are a number of limitations and caveats and they vary model to model and across IOS releases.

If at all possible in your environment you are much better off extracting Netflow data from a router.

Hi Jake

 

I am having the same module C3KX-SM-10G but still I am not able to configure the netflow. Can you please guide me on it,

I just had to go through this

I just had to go through this and I created a post with step by step instructions on how to get this to work.  I needed to setup NetFlow for several VLANs and used a SPAN to mirror them over to an interface on the C3KX-SM-10G.  We also had to create a loopback cable to get the fiber SFP to come up.  Hope this helps!
