In this video blog, Anthony Sequeira walks students through troubleshooting a missing NAT Translation table entry.
In this Cisco Video Blog, Anthony Sequeira demonstrates the difference between frame-relay map and frame-relay interface-dlci.
This post discusses the use of a subnetting conversion chart in the ICND1 and ICND2 exams. We all know that we need to learn TCP/IP Subnetting for success in the ICND1 and ICND2 exams. In fact, we must completely master it and understand how and why it works the way it does, and then we have to learn tricks and strategies to ensure that we can succeed in the exams given the intense number of questions we will face and their complexity. Note that it is very important that you master subnetting first as a subject, and then you can go on and learn the shortcuts for solving the questions.
This post aims to help our CCNA students when it comes to Frame Relay terminology.CCNA students consistently report that one of their trouble areas in the exam is Frame Relay and its terminology. It is second only to subnetting when it comes to student reports of exam difficulties. In this Epic Live Blog post, I am going to cover the terms you should know about Frame Relay for the real world and your certification exam, and of course, I am going to use plain English and simple analogies to assist you.
Data Terminal Equipment (DTE)
DTE equipment is electronic stuff that needs to connect to the Frame Relay network in order to communicate. In our case, we often think of our Cisco router as the DTE. The DTE could also be a multiplexor, concentrator, bridge, or even simply a Frame Relay I/O board in some other piece of networking equipment.
Data Communications Equipment (DCE)
This is typically what we term the Frame Relay networking devices of the Frame Relay Service Provider. These DCE devices provide clocking and switching services to the DTE equipment and they make sure our happy little data frames make their way safely through the big and scary Wide Area Network (WAN).
