hi, i am looking for recommendations for managed switches with security options and flow exports (sFlow or NetFlow). i really need a smart switch that can help me block rogue dhcp servers on our network by figuring out which port it's communicating on and/or blocking the MAC address. these rogue servers are usually NOT on the same subnet of our network.
i've looked for hours but there's a lot of different terms that the companies use and vastly different prices for switches that seem to do the same thing. I need a 48 port (or two 24 port) managed switch recommendations that are reliable and offer security options. This is for a small business so price should (hopefully :-) be low.
