Cisco VGD 1T3 Voice Gateway Software Configuration Guide
EXEC commands are not saved when the software reboots. Commands that you issue in a configuration
mode can be saved to the startup configuration. If you save the running configuration to the startup
configuration, these commands will execute when the software is rebooted. Global configuration mode
is the highest level of configuration mode. From global configuration mode, you can enter a variety of
other configuration modes, including protocol-specific modes.
ROM monitor mode is a separate mode that is used when the Cisco IOS software cannot load properly.
If a valid software image is not found when the software boots or if the configuration file is corrupted at
startup, the software might enter ROM monitor mode. Use the question symbol (?) to view the
commands that you can use while the device is in ROM monitor mode.
