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
#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
Extended IPv4 ACLs? No problem. Matching packets going towards the client? A little more of a problem. Deciding whether you need to match ARP and OSPF in your ACL? Even more of a problem. This latest drill makes you think
This next Extended IPv4 ACL Drill continues to focus on some key ACL concepts. You have to think about where the ACL will reside, and for what direction of packet flow, before choosing the syntax of the commands. This next
The previous post listed a set of ACL requirements that require an IPv4 Extended ACL. Your job: using those requirements, configure an extended named ACL. Of course, this post makes no sense without the post that states the requirements, so check
Extended Access Control Lists (ACLs) can be a challenge for many reasons. In the first few posts in this series, these ACL exercises will focus on just a few of those issues. In particular: The concept and syntax to match
This latest lab breaks the config lab mold just a tad, but for a good reason. It looks like a straightforward config lab, requiring just 10 minutes or so to do on paper. But it sets you up for one
Are you comfortable matching packets with extended IPv6 ACLs? How about with TCP and UDP ports in those ACLs? Here’s a 10-minute lab exercise to practice; all you need is the time and a piece of paper or a place
No muss, and just a little fuss with thinking about SNMP, today’s lab is mostly about how to match packets with an extended numbered ACL. Do the lab for yourself, and check here when you’re done.
