CCNAv7 – Enterprise Networking, Security, & Automation (ESNA) – Packet Tracer 5.4.13 – Extended ACLs

In this comprehensive and exhaustive techtorial on Packet Tracer activity 5.4.12 (Configuring and Applying Named & Numbered Extended ACLs) we take a deep dive at how we can turn a list of written requirements into an effective Access Control List (ACL). We configure R1 with both a named and a numbered extended ACL and then review Cisco best practices with respect to placement of the ACLs and the implications of misplacing the ACLs. We also look at the validation and confirmation commands to help up determine on which interface an ACL might be applied and what Access Control Entries (ACEs) make up of the ACL.

*This techtorial/Packet Tracer activity is all done running Packet Tracer version 7.3.0 (for the Mac) which was recently released and is the MINIMUM version you can use for any of the new CCNAv7 curriculum activities! Be sure to leave your feedback and questions below and I hope I have earned the privilege of your time!

Enjoy!
