Building, Configuring, and Troubleshooting ACLs
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.
What you'll learn
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, Building, Configuring, and Troubleshooting ACLs, you'll 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'll be able to write your own access control lists to filter whatever traffic you want to either permit or deny on your networks.
