•
Use to specify the configuration with which the system is rebooted.
CAUTION: All versions of this command except those using the
running-configuration or startup-configuration keywords erase the current
system running configuration. Before issuing one of those versions, you
might want to save the running configuration to a .cnf file by issuing the
copy running-configuration command.
•
You can require the system to reboot from a configuration file.
To specify an existing system configuration (.cnf) file that the system uses for the next
reboot and all subsequent reboots:
host1(config)# boot config newconffile.cnf
To specify an existing system configuration (.cnf) file that the system uses only on the
next reboot. On subsequent reboots, the system will use the running configuration
current at the time of that reboot:
host1(config)# boot config newconffile.cnf once
•
You can require the system to reboot from an existing local script (.scr) file that the
system uses only on the next reboot. On subsequent reboots, the system will use the
running configuration current at the time of that reboot:
host1(config)# boot config scriptfile.scr
Configuring this option causes the system to ignore—only at the next reboot—an
autocfg.scr file that you may also have configured.
•
If you specify a .cnf file, upon the next reboot the system resets to the factory defaults;
it then opens the .cnf file and begins applying it immediately. If you specify a .scr file,
upon the next reboot the system resets to the factory defaults; it then waits for a
600-second countdown timer to expire before applying the script. This period gives
the line modules an opportunity to fully initialize before configuration begins. Upon
timer expiration or system initialization (whichever occurs first), the script executes
regardless of the state of the line modules. You can escape from the countdown by
pressing Ctrl+c; the system prompts you to execute the script immediately or return
to the system console.
•
You can require the system to reboot from the configuration running on the system at
the time of the reboot.
If the system is in Automatic Commit mode:
host1(config)# boot config running-configuration
If the system is in Manual Commit mode:
host1(config)# boot config startup-configuration
See “Saving the Current Configuration” on page 264 in “Managing the System” on page 239,
for information about Automatic and Manual Commit modes.
