Privileged Exec Mode; Rom Monitor Mode; Global Configuration Mode - Cisco Catalyst 8540 MSR Configuration Manual

Accessing Each Command Mode

Privileged EXEC Mode

The privileged EXEC command set includes all user-level EXEC mode commands and the configure
command, through which you can access global configuration mode and the remaining configuration
submodes. Privilege EXEC mode also includes high-level testing commands, such as debug, and
commands that display potentially secure information.
To enter privileged EXEC mode from EXEC mode, use the enable command and enter your password;
the prompt changes to the ATM switch router's host name followed by the pound sign (#):
Switch> enable
Password:
Switch#
To exit from privileged EXEC mode back to EXEC mode, use the disable command.
Switch# disable
Switch>
The system administrator uses the enable password global configuration command to set the password,
which is case sensitive. If an enable password has not been set, privileged EXEC mode can only be
accessed from the console.

ROM Monitor Mode

ROM monitor mode provides access to a basic system kernel, from which you can boot the ATM switch
router or perform diagnostic tests. If a valid system image is not found, or if the configuration file is
corrupted, the system might enter ROM monitor mode. The ROM monitor prompt is the angle bracket:
>
You can also enter ROM monitor mode by intentionally interrupting the boot sequence with the Break
key during loading. For a description of this process, refer to the Configuration Fundamentals
Configuration Guide.
To return to EXEC mode from ROM monitor mode, use the continue command:
> continue
Switch>

Global Configuration Mode

Global configuration mode provides access to commands that apply to the entire system. From global
configuration mode you can also enter the other configuration modes described in the following
subsections.
To enter global configuration mode from privileged EXEC mode, enter the configure command and
specify the source of the configuration commands at the prompt; the prompt changes to the ATM switch
router's hostname followed by (config)#:
Switch# configure
Configuring from terminal, memory, or network [terminal]? <CR>
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#
