Cisco ICND2 1.1: Configuring and Troubleshooting ACLs

This course is included in our On-demand training solution.


Standard and extended Cisco IOS access control lists (ACLs) can be used to classify IP packets. Using ACLs, you can apply a number of features to the classified packets, such as encryption, policy-based routing, quality of service (QoS), Network Address Translation (NAT), and Port Address Translation (PAT).
You can also configure standard and extended Cisco IOS ACLs on router interfaces for access control (security). Cisco IOS features are applied on interfaces for specific directions (inbound versus outbound). This course describes the steps that you use to configure named and numbered, standard, and extended access control lists (ACLs). This course also explains how to verify that the ACLs are functioning properly, and discusses some common configuration errors to avoid.
