Setting the CONFIG_FILE Environment Variable

You can specify multiple configuration files with the set boot auto-config command by separating them
with a semicolon (;). You must specify both the device name and the filename for each configuration file.
Note You cannot prepend or append configuration files to the CONFIG_FILE environment variable. Entering
the set boot auto-config command erases any list of configuration files previously specified using the
set boot auto-config command.
To set the CONFIG_FILE environment variable, perform this task in privileged mode (depending on
your supervisor engine and switch type):
Task
