I've been asked to research and purchase a 12 to 24 port switch that has the ability to filter traffic on individual ports based on IP address. Meaning, if traffic comes into a port and it doesn't have a particular IP address that traffic is blocked.
What is this feature or functionality called? I'm searching Google/NewEgg/etc for "switch ip filtering" but all the results are generic and unhelpful
Obviously I don't want to pay for more functionality than I need. So do I need a full layer 3 switch? Is that the option for the IP filtering capability I need? ACLs?
