Switch Boot Optimization
The normal switch boot process involves a memory test, file system check (FSCK), and power-on
self-test (POST).
The boot fast command in global configuration mode is enabled by default to permit switch boot
optimization, which disables these tests and minimizes the bootup time. However, after a system crash
this feature is automatically disabled.
Reload sequences occur immediately if your switch is set up to automatically bring up the system by
using information in the BOOT environment variable. Otherwise, these reload sequences occur after you
enter the manual boot command in bootloader configuration mode.
First Reload
The switch disables the boot fast feature and displays the following warning message:
“Reloading with boot fast feature disabled”
After the system message appears, the system saves the crash information and automatically resets itself
for the next reload cycle.
Second Reload
The boot loader performs its normal full memory test and FSCK check with LED status progress. If the
memory and FSCK tests are successful, the system performs additional POST tests and the results are
displayed on the console.
The boot fast feature is reenabled after the system comes up successfully.
Feature Default Setting
Operating system software image The switch attempts to automatically boot up the system using
information in the BOOT environment variable. If the variable is not set,
the switch attempts to load and execute the first executable image it can
by performing a recursive, depth-first search throughout the flash file
system.
The Cisco IOS image is stored in a directory that has the same name as
the image file (excluding the .bin extension).
In a depth-first search of a directory, each encountered subdirectory is
completely searched before continuing the search in the original
directory.
Configuration file Configured switches use the config.text file stored on the system board in
flash memory.
A new switch has no configuration file.
