Chapter 5
Managing a Cisco Internetwork
THE CCENT EXAM OBJECTIVES COVERED IN THIS CHAPTER INCLUDE THE FOLLOWING:
- Describe the operation of Cisco routers (including: router bootup process, POST, router components)
- Manage IOS configuration files (including: save, edit, upgrade, restore)
- Manage Cisco IOS
- Verify network status and router operation using basic utilities (including: ping, traceroute, telnet, SSH, arp, ipconfig), SHOW & DEBUG commands
Here in Chapter 5, I'll show you how to manage Cisco routers on an internetwork. The Internetwork Operating System (IOS) and configuration files reside in different locations in a Cisco device, so it's really important to understand both where these files are located and how they work.
You'll be learning about the main components of a router, the router boot sequence, and the configuration register, including how to use the configuration register for password recovery. After that, you'll find out how to manage routers by using the copy command with a TFTP host when using the Cisco IOS File System (IFS).
I'll wrap up the chapter with an exploration of the Cisco Discovery Protocol (CDP), and you'll learn how to resolve hostnames and some important Cisco IOS troubleshooting techniques.
