show boot Field Descriptions
Description
Displays a semicolon separated list of executable files to try to
load and execute when automatically booting.
If the BOOT environment variable is not set, the system attempts
to load and execute the first executable image it can find by
using a recursive, depth-first search through the flash file
system. In a depth-first search of a directory, each encountered
subdirectory is completely searched before continuing the
search in the original directory.
If the BOOT variable is set but the specified images cannot be
loaded, the system attempts to boot the first bootable file that it
can find in the flash file system.
Displays the filename that Cisco IOS uses to read and write a
nonvolatile copy of the system configuration.
Displays the filename that Cisco IOS uses to read and write a
nonvolatile copy of the private configuration.
Note
Displays whether a break during booting is enabled or disabled.
If it is set to yes, on, or 1, you can interrupt the automatic boot
process by pressing the Break key on the console after the flash
file system is initialized.
Displays whether the switch automatically or manually boots. If
it is set to no or 0, the boot loader attempts to automatically boot
the system. If it is set to anything else, you must manually boot
the switch from the boot loader mode.
Displays a semicolon separated list of loadable files to
dynamically load during the boot loader initialization. Helper
files extend or patch the functionality of the boot loader.
Displays the buffer size that Cisco IOS uses to hold a copy of the
configuration file in memory. The configuration file cannot be
larger than the buffer size allocation.
Description
Specifies the size of the file system-simulated NVRAM in flash memory.
Specifies the filename that Cisco IOS uses to read and write a nonvolatile
copy of the system configuration.
Enables interrupting the automatic boot process.
Enables manually booting the switch during the next boot cycle.
Specifies the filename that Cisco IOS uses to read and write a nonvolatile
copy of the private configuration.
Specifies the Cisco IOS image to load during the next boot cycle.
Only the Cisco IOS software can read and write a copy
of the private configuration file. You cannot read, write,
delete, or display a copy of this file.
