I have been asked to suggest a Cisco Nexus Switch model to buy on Ebay. The Nexus should be able to act as Supervisor for N2K FEX, L2 / L3 capability, 10G, and BGP if possible. If SD-WAN possible, it will help, but not mandatory.
I was trying to Google the info but realized that the NX-OS license is not fixed anymore on Cisco and features need to be licensed. Also, seems like the licenses have expiry dates. I don't want to make a wrong recommendation, because of my lack of knowledge.
So, can some kind folks here please suggest a couple of models of Nexus switches that are not too expensive which I can suggest that they purchase on Ebay? Budget: 500 - 1000 USD. Thanks in advance for your guidance.
