This article takes a look at TCP/IP (version 4), how it is structured and used to route traffic from source to destination across multiple intermediary points. It also covers a couple of the other protocols that are directly connected into the TCP/IP suite including TCP, UDP and ICMP.
This article takes a look at how Cisco organizes their configurations within a device, how these different configurations relate to each other and how they can be managed to ensure that the desired result is achieved. It also covers the procedure that can be used should the passwords to access the device be lost or forgotten.
This article takes a look at some of the most basic network verification commands that can be used on Cisco equipment and discusses the information that can be obtained from these commands.
One of the first and most important things that a new engineer needs to learn is how to actually connect to a Cisco device. This article will only cover the configuration of CCP which performs all of the functions of SDM and adds support for unified communications.
In August 2015, representatives of the United States Department of Defense (aka DoD, pronounced "Dee-oh-Dee") signed the 8140 directive. It replaces the now-outmoded (but not forgotten, for reasons I'll explain soon) 8570 directive. Both 8570 and 8140 require DoD personnel and contractors to obtain certifications in their work area specializations, particulary for IT-related job roles. This means that active duty military and DoD civilians who work in and around IT must obtain a variety of security credentials based on NIST's definition for the National Initiative for Cybersecurity Education (aka NICE). The devil, as always, is in the details, so let's look at some of them more closely.
