In this post, i will show the correct configuration and step by step how to get 100% for this Packet Tracer Activity. Mistake in using IP Address will not increase your mark although the IP address you use also applicable and correct for that particular purpose. However, you must be very precise when dealing with ACL and Packet Tracer Activity. It doesn’t involve advanced ACL such as reflexive, dynamic or time based ACL. ACL in this Packet Tracer Activity is using standard and extended ACL. To be specific, the title for the packet tracer activity is Configure IP ACLs to Mitigate Attacks. Chapter 4 Packet Tracer Activity A Network Security is about ACL. So using these tools to verify a network diagram can be a good exercise using PT.This post is solution or answer for Packet Tracer Activity Chapter 4 Network Security. For example, the output will guide you through the idea of learning a neighbor’s hostname, the interface used by the neighbor, and the local device’s interface. Unfortunately, that prevents the interfaces used in PT from matching the interfaces used in the book examples, but we still think you can learn from re-creating the book examples.Īlso, we suggest that you use PT to get a general idea of what you see with CDP and LLDP, but avoid trying to make a list of specific rules and expectations based on the output in PT. We used 2960 switches for the supplied PT files because those give the best LLDP support in PT. We see some differences in command support based on the PT device models, particularly with LLDP and switches. But both CDP and LLDP work well enough for you to re-create many of the examples from the book. The very function of CDP and LLDP poses challenges when comparing what PT can do in comparison to real gear. Then NTP inside PT can do the rest without waiting 15-30 minutes.ĬDP and LLDP discover details about neighboring devices. The goal: Press enter on the 2nd command at about 1 second after you pressed enter on the first command.įollowing this process, you will manually set the time to close to the same time. Get ready to issue the first command on that device, and within 1 second, switch to the second device and press enter. Just leave the command on the command line: Type these two commands on the two devices on which you want the time to converge – but do not press enter. NTP converges more slowly in NTP than in real gear. That said, you may get frustrated waiting for NTP to converge unless you take extra care. But you can definitely learn some details about NTP. The per-example accordion notes below give some insight into the known issues.

NTP works well enough with PT so you can re-create many of the examples. However, if you have access to any real gear, this is definitely a topic you should instead practice on real. That said, you should still be able to try some of the logging features in PT. We added notes in the per-Example notes below in this post pointing out command issues that we found. You can still learn about logging and Syslog using Cisco PT. You can read the examples as usual and learn a lot from those. The book covers the basics, as you might expect, but from a command perspective, that section covers many command options. We tested in PT 7.3 vs the flow used in the book examples and eventually decided it was not worth trying to re-create the examples. Let’s examine Chapter 9 of the CCNA 200-301 Cert Guide, Vol 2 as three separate topics, per the three major sections in the chapter:
