Defaults The environment variables have these default values:
MANUAL_BOOT: No (0)
BOOT: Null string
ENABLE_BREAK: No (Off or 0) (the automatic boot process cannot be interrupted by pressing the
Break key on the console).
HELPER: No default value (helper files are not automatically loaded).
PS1: switch:
CONFIG_FILE: config.text
BAUD: 9600 b/s
HELPER_CONFIG_FILE: No default value (no helper configuration file is specified).
SWITCH_NUMBER: 1
SWITCH_PRIORITY: 1
Note Environment variables that have values are stored in the flash file system in various files. The format of
these files is that each line contains an environment variable name and an equal sign followed by the
value of the variable. A variable has no value if it is not listed in this file; it has a value if it is listed in
the file even if the value is a null string. A variable that is set to a null string (for example, “ ”) is a
variable with a value. Many environment variables are predefined and have default values.
Command Modes Boot loader
Command History
Usage Guidelines Environment variables are case sensitive and must be entered as documented.
Environment variables that have values are stored in flash memory outside of the flash file system.
Under normal circumstances, it is not necessary to alter the setting of the environment variables.

configuration command.
The BOOT environment variable can also be set by using the boot system filesystem:/file-url global
configuration command.
The ENABLE_BREAK environment variable can also be set by using the boot enable-break global
configuration command.
The HELPER environment variable can also be set by using the boot helper filesystem:/file-url global
configuration command.
The CONFIG_FILE environment variable can also be set by using the boot config-file flash:/file-url
global configuration command.
The HELPER_CONFIG_FILE environment variable can also be set by using the boot helper-config-file
filesystem:/file-url global configuration command.
