I'm somewhat new to networking and I have been looking to pick up an older Nexus switch to learn more about it and the converged features. I found a Nexus 3048 (for what I assume to be a reasonable price) on eBay however the seller states that there are no licences for it.

So the question is can I use a Nexus NX-OS switch without any licences? Is there a default base license that comes with them?

Thank you anyone that can help, Greg

  • Yes, there's a built-in license you aren't supposed to be able to erase. Despite what Cisco want's you to believe, the doctrine of first sale applies, so the user license is transferable. (if I buy X, I can turn around and resell X, exactly as I received it, and any right-to-use licenses go with it.)

In the Cisco Nexus 3048 Switch Data Sheet in table 3 you can see this:

(sorry for the image I cannot get the formatting right with a text paste)

So without specific license you get basic features with the system default. That is layer 2 features.

The switch may have been shipped with a base license, required for layer 3 (routing) features but you should ask the vendor for the result of a "show license" command.

  • Thank you for that, the seller showed a printout of the show license cmd and it returned nothing. I was hoping to be able to do IVR, but if I don't have a license maybe I should go with a 5000 series and use my router as router on a stick

  • Have them try show license usage instead. Jan 23, 2019 at 21:16
