NetFlow/NetQOS on a 3750x switch

[andrewb]

Hello, I have 3750x running c3750e-universalk9-mz.122-55.SE5 layer 3 capable. Im trying to enable net flow on the switch but for some reason the flow commands dont appear to be available in config t mode. Are there some other global commands that have to be enabled first in order for the netflow commands to be available or is it  the image that doesnt support netflow?

Hey Andy,

Regarding your question, 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 check the running feature set with command "show license all" and change if required.

HTH.

Thanks Rajeevsh,

I ran the command I got the output below, i do see ipbase in there but dont know if that means its active..

Maybe it needs to have IP services as you pointed out..

Thanks for looking at this..

I also ran it on another 3750x where netflow commands seem to work and the output is different..see below:

Hey Andy,

The license on the box is ipbase:

StoreIndex: 1   Feature: ipbase                            Version: 1.0
        License Type: Permanent
        License State: Active, In Use <<<<<< look here
        License Priority: Medium
        License Count: Non-Counted

So it should support netflow, however only other thing required is the network servie module, so have a look on this link for more information:

Also i checked that minimum IOS requirement for this service module to work is 15.(0)1SE and you are running 12.2(55)SE5 so I believe you need a hardware upgrade as well.
