Understanding Access Control Lists Network Fundamentals Part 14
ACLs, or Access Control Lists, are one of the fundamental ways to control or influence the traffic flowing through your network.
They can be used in several different ways, but in this video we’ll look at how to use ACLs as a packet filter. Packet filters use ACL’s to control traffic that is and is not allowed through the network.
An ACL is, as the name suggests, a list containing Access Control Entries (or ACE). Each entry is a rule, with ‘match’ conditions. If traffic matches these conditions, then an action (permit or deny) is applied.
Standard ACL’s are the original type, and can only match based on source address. Extended ACLs are newer can can match on a variety of criteria.
There are several ways that ACLs can be configured. Numbered ACLs, is where each entry in the ACL is identified by a number. Named ACLs are more advanced, and group the entries inside a container.
This video contains a lab, where you can see how to configure all these options.
