Entering EXEC Commands from a Configuration Mode
EXEC commands can be executed from any configuration mode by preceding the command with the do
keyword. Executing EXEC commands from a configuration mode allows you to display the state of the
system without exiting the configuration mode. For example:
RP/0/0/CPU0:router(config)# do show version

ROM Monitor
(ROMMON)
The ROM Monitor is a bootstrap program that initializes the hardware and boots the system when a
router is powered on or reset. ROM Monitor mode is also known as ROMMON, which reflects the
CLI prompt for the mode.
rommon B1>
During normal operation, users do not interact with ROMMON. This mode is accessed only by
manually interrupting the boot process and placing the system in ROMMON. Once in ROMMON,
you can perform ROM Monitor tasks, including reinstallation of the Cisco IOS XR software,
password recovery, and other diagnostic tasks.
The ROM Monitor CLI mode is accessible only from a terminal connected directly to the Console
port of the primary RP, a terminal-modem connection to the AUX port, or through a terminal server.
For information and instructions on using ROM Monitor mode, see Cisco IOS XR ROM Monitor
Guide for the Cisco XR 12000 Series Router.
