200-301 V2 Part 1: IP ACLs
Config Lab: Extended Numbered ACL 1
Ready to review how to match subnets with extended ACLs? And how to match well-known ports? Today’s lab lets you do just that. Along the way, you get to think about where to place the ACL to most efficiently filter
Config Lab: Standard Named ACL 1
Standard named ACLs follow a nice simple format, which is great for getting started with ACLs. This next lab gives you some exercise on the basic syntax, while throwing in a few issues related to the application of the ACL.
Config Lab: Standard Numbered ACL 1
Write a 1-line ACL to match something? Easy. Write a several line ACL with a bunch of requirements? A little harder. Choosing where to put that multi-line ACL, when the ACL requirements span multiple subnets? Yet another bump. Combining all
CCNA Packet Tracer Labs – CCNA Vol 2, Chapter 3
CCNA Volume 2's first ACL chapter gets over the big fundamental Access Control List (ACL) concepts and configuration, with Chapter 3 (the subject of this post) moving on to more detailed ACL topics. In particular, this chapter examines extended ACLs,
CCNA Packet Tracer Labs – CCNA Vol 2, Chapter 2
Access Control Lists (ACLs) may be one of the most uncomfortable topics to learn during your first few hours reading about the topic. Getting into lab early in your reading can help, so take advantage of this post and re-live
A: TCP Transport Ports
You might have missed this latest #CCNA question because configuring routers and switches does not reinforce the concepts required to answer this question. If you do want to do some labbing to learn more, download Wireshark (or some other network
Q: TCP Transport Ports
Most CCNA candidates focus on the topics that require deeper learning, topics that you need to configure, verify, and troubleshoot on routers and switches. At the same time, Cisco includes a small set of topics for which you need only
A: Matching Port Numbers with ACLs 1
First, think of TCP headers, and the source port and destination port. Then think about the predictable port – the well-known port – and whether it will be the source or destination port. Then think about the syntax of the
Q: Matching Port Numbers with ACLs 1
#CCNA ACL questions can uncover your weaknesses even without a detailed and complicated list of requirements to place in a single ACL. In fact, my “Acing the CCNA Exam” live course on Safari features ACL Port Matching as one of
