Appendix A Catalyst 3750 Metro Switch Boot Loader Commands
set
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 bps
HELPER_CONFIG_FILE: No default value (no helper configuration file is specified).
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 History
BAUD
rate
—The rate in bits per second (bps) used for the console. The software
inherits the baud rate setting from the boot loader and continues to use this value
unless the configuration file specifies another setting. The range is from 0 to
4294967295 bps. Valid values are 50, 75, 110, 150, 300, 600, 1200, 1800, 2000,
2400, 3600, 4800, 7200, 9600, 14400, 19200, 28800, 38400, 56000, 57600, 115200,
and 128000.
The most commonly used values are 300, 1200, 2400, 9600, 19200, 57600, and
115200.
HELPER_CONFIG_FILE
filesystem
:/
file-url
—The name of the configuration file
to be used by the helper image. If this is not set, the file specified by the
CONFIG_FILE environment variable is used by all versions of software that are
loaded, including the helper image. This variable is used only for internal
development and testing.
