Selecting specific traffic as it flows through a network is valuable to make networks function in a predictable way. This course, will walk you through the operation, implementation, and troubleshooting of standard and extended access control lists.
Access Control Lists (ACLs) are an important and useful tool on a data network. ACLs allow an administrator to select traffic and filter traffic as it flows through a network. In this course, Access Control Lists (ACLs) for Cisco CCNA 200-125/100-105, you will first examine how standard and extended IPv4 access lists operate. Next, you'll learn how to implement each type of list on a router. Finally you'll explore common errors and how to troubleshoot ACLs using Wireshark. By the end of this course, you will be able to write your own access control lists to filter whatever traffic you want to either permit or deny on your networks.
Course Overview Hi, everyone, my name is Ross Bagurdes, and welcome to my course, Access Control Lists. I'm a network engineer with 20 years' experience building and managing enterprise networks and teaching people about them. Access control lists are one of network engineer's greatest tools to manipulate traffic flow on a network. Understanding ACLs will allow you to manage a network, contain malicious traffic, and restrict access to devices and services. In this course, we will learn about standard and access controls lists and how they can be applied to interfaces and other functions on a router. By the end of this course, you will be able to use Wireshark to build and implement an access control list, as well as having a method to troubleshoot ACLs that are not functioning as desired. Before beginning this course, you should definitely be familiar with IP addressing, packet headers, TCP and UDP segments and their headers, as well as how packets are routed through a network. And all this information can be learned in previous videos in this CCNA training series. From here you should feel comfortable diving into the Network Address Translation course. I hope you'll join me on this journey to learn standard and extended access control lists with the Access Control List course at Pluralsight.
