Cisco runs a brilliant business dedicated to keeping the world’s networks running quick and securely. The only problem is that the high level of documentation on hardware and software products can make it confusing when trying to implement a new network design or modification.
The first reference material to consider is Cisco posters. These posters, often found free through the Cisco Academy or through third party retailers, cover many topics such as router commands and network hardware specifications. Keeping up a Cisco poster in your room is a great way to learn all of the ins and outs of Cisco products a little bit each day at a time.
Cisco also has great software utilities that can guide you through the process of learning how networks operate. Packet Tracer is their flagship software suite, which is only offered to those who are either in the Cisco Academy or have been in the past. This free program is a godsend for teachers, who are able to easily create labs and print them off for students.
You can find other types of software as well, that instead acts like a dictionary or reference guide. These programs are free for everyone, and not just Cisco students. Having a Cisco dictionary around is ideal for the workplace, for when you need to know what a command or piece of hardware does immediately. Students find it useful, as explanations are given in addition to command names.
Cisco has their own line of books and learning materials. The only downside is that these manuals are often hard to read and require attention to detail in order to allow the information to sink in. Books also are subpar in terms of quick reference, as they are thick with information and flipping through pages can be time consuming. Desktop software and posters are quicker, but books tend to be more thorough in explanations.
If all you need is a quick reference, consider using the help tool in the Cisco IOS. This help tool will quickly show you different commands that you are able to use, show how to use them, and give a brief description. It will not teach you how to use the commands in detail, so you will need to consult an expert or book for that. The in-program help feature is best suited for someone who might have forgotten a simple command.
In Conclusion
There are plenty of references to find in Cisco materials. Depending on what you need, you might want the simple desktop program or an expensive book to help you out. Cisco classes are tough work, so do not feel discouraged over the course of your networking hardware and software studies.
