Access Control List Explained

ACL stands for Access Control List. ACL either permits or denies traffic. You can think of an ACL as a traffic cop. It inspects every packet coming in and going out of a network device on a per-interface basis and either permits or denies traffic based on a predefined checklist 🤓

In this video, I explain ACLs at a high level. I also provide an overview of various types of ACLs. All in about 5 minutes 👨‍🏫

This video is part of my popular Tech Nuggets series. The goal of tech nuggets is to cut to the chase & explain tech concepts in the form of small nuggets that you can consume right before walking into a customer meeting or a job interview 🧳

That was an awesome and clear explanation of what ACLs and ACEs are, but it would have been nice to see some examples of the function of real ACLs, like DENY ICMP or some other traffic manipulation... There seems to be so many logic bombs with ACLs, you can find yourself locked out of your own switch if you aren't careful...
