Chapter 2 Understanding The User Interface; User Interface Overview - Cisco Catalyst 8540 MSR Configuration Manual

Understanding the User Interface
This chapter describes the ATM switch router user interface and provides instructions for using the
command-line interface (CLI).
This chapter provides advanced configuration instructions for the Catalyst 8540 MSR,
Note
Catalyst 8510 MSR, and LightStream 1010 ATM switch routers. For complete descriptions of the
commands mentioned in this chapter, refer to the ATM Switch Router Command Reference publication.

User Interface Overview

The user interface for the ATM switch router provides access to several different command modes, each
with related commands. Users familiar with the Cisco IOS user interface will find the interfaces very
similar. This chapter describes how to access and list the commands available in each command mode,
and explains the primary uses for each command mode.
For security purposes, the user interface provides two levels of command access: user and privileged.
The unprivileged user mode is called user EXEC mode; the privileged mode is called privileged EXEC
mode, and requires a password.
Note Because all commands available in user EXEC mode are also available in privileged EXEC mode, user
EXEC mode is referred to as EXEC mode in this guide.
From the privileged level, you can access global configuration mode; from global configuration mode
you can access numerous submodes that allow you to configure specific, related features. Read-only
memory (ROM) monitor mode accesses a basic system kernel to which the ATM switch router may
default at startup if it does not find a valid system image, or if its configuration file is corrupted.
