ABSTRACT
Breaking Down the Protocols Network managers tasked with securing organizational resources need to control who can access network devices and what they can do. In Chapter 6, “Implementing Non-AAA Authentication,” you learned about enable, console, line, and local passwords. Using these passwords is not without problems. Briefly, the problems are:
You must maintain local passwords on all your routers and update them all when you change passwords. Now, in a small network, this might not seem like such a big deal; but when you have hundreds of routers, this is a mammoth task guaranteed to go wrong. You could forget one device or you might not change the password in a timely manner, not to mention the labor associated with the task itself.
