Config-Only Mode
Config-Only mode is entered if the configuration file that you are using is empty or
no protocols are configured. Config-Only mode can also be entered manually to
recover from an invalid configuration that is causing the router to crash during
start-up.
Automatic Entry Into Config-Only Mode
Config-Only mode is entered if the router detects a problem during operation or
during router initialization.
The following conditions cause the router to enter Config-Only mode:
vThe software load does not match the device configuration. Specifically, an
attempt is made to configure a device or data link that is not supported by the
software load.
vDevices are configured but no protocols are configured.
If the router enters Config-Only mode because an unsupported device is configured:
vChange the device information to match the hardware installed in (and supported
by) the router, or change the unsupported device to “null device”.
vEnter the Restart or Reload command from the Config (only)> prompt.
vThe router will automatically enter OPCON (*).
If no protocols or devices are configured other than default devices, the router
comes up in EasyStart. For additional information, see “Using EasyStart” on
page 40 .
Manual Entry Into Config-Only Mode
Toenter Config-Only mode, do one of the following:
vToreload or restart the router with no configuration.
Toreload or restart the router with no configuration, use the cc command.
vReload or restart the router with no protocols configured.
vUse the bootstrap monitor bc command to boot to config-only mode.
Note: If autoboot is enabled and if you press Ctrl-C while the software is loading,
you go directly to the bootstrap monitor >prompt without seeing the text and
you can skip step 1. Otherwise, the following text appears:
