Chapter 4 Router Components

Introduction

Whether accessed from the console or by a Telnet session through an auxiliary port, the router can be placed in several modes. Each mode provides different functions:

• User EXEC mode-A "look-only" mode in which the user can view some information about the router, but cannot change anything.

• Privileged EXEC mode-Supports the debugging and testing commands, detailed examination of the router, manipulation of configuration files, and access to configuration modes.

• Setup mode-Presents an interactive prompted dialog box at the console that helps the new user create a first-time, basic configuration.

• Global configuration mode-Implements powerful one-line commands that perform simple configuration tasks.

• Other configuration modes-Provide more complicated multiple-line configurations.

• RXBOOT mode- A maintenance mode that can be used, among other things, to recover lost passwords.

• The router has modes for examining, maintaining, and changing the components. In the examining mode, what does the router do?

• Show commands are used for examination. What does the show command examine?

• Use CDP to show entries about neighbors.

• Access other routers with Telnet.

• Test network connectivity layer by layer. Testing commands include ping, trace, and debug. What is the difference between trace and ping?
