Editing a Boot
Configuration
File
You can edit a boot configuration file using a text editor on your
management workstation. To edit a file, you must upload it from the switch
to your management workstation. You cannot edit a boot configuration file
directly on the switch. Once you have edited the file, you can download it
back to the switch and make it the active boot configuration file.
For instructions on how to upload a configuration file from a switch to your
management workstation, refer to “Uploading a System File” on page 209.
For instructions on how to download a configuration file from your
workstation back to the switch, refer to “Downloading a System File” on
page 202. For instructions on how to designate an active boot
configuration file, refer to “Setting the Active Boot Configuration File” on
page 179.
Here are several guidelines to editing a boot configuration file:
ˆ The text editor must be able to store the file as ASCII text. Do not
insert special formatting codes, such as boldface or italics, into a boot
configuration file.
ˆ The configuration file must contain AT-S62 command line commands.
You enter the commands you want the switch to perform when reset or
power cycled. For a description of the commands, refer to the AT-S62
Command Line User’s Guide.
ˆ A boot configuration file is divided into sections with each section
devoted to the commands of a particular function. For example, the
VLAN Configuration section should contain commands for creating
VLANs or for setting the VLAN mode. When entering new commands,
be sure to place them in the appropriate sections.
ˆ Each command must start flush left against the margin.
ˆ To comment out a command so that the switch does not perform it,
precede the command with the symbol “#”.
ˆ You should test the commands manually by entering them at the
command line before inserting them into a boot configuration file. This
helps to insure that you understand the syntaxes and parameters of
the commands and that the commands produce the desired results.
Troubleshooting
a Boot Configura-
tion File
If a boot configuration file contains an invalid or incorrect command, the
switch, when reset or power cycled, will stop processing the configuration
file at the point of the invalid command. The invalid command and any
commands following it in the file will not be performed. To troubleshoot a
configuration file, start a local management session with the switch and
reset the device. Messages on the screen during the boot up and
configuration process will indicate the line in the configuration file with the
error. You can download the file to your management workstation and edit
it to correct the error.
