Cisco ICND2 1.1: Introducing ACL Operation

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


Access control is very important within any organization and once you understand the uses of Access Control Lists (ACLs), you can determine how to implement them on your Cisco network. 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).
