This section provides the details of the files downloaded and how they are utilized during the automatic<br />
configuration process. The main component files are:<br />
• Instruction file —The instruction file is the initial file required for the automatic remote configuration<br />
process to occur. The instruction file is stored in the TFTP server with the .alu extension. For further<br />
details, see “Instruction File” on page 12-12<br />
• Firmware upgrade files—The firmware files or image files differ for different Omni<strong>Switch</strong><br />
platforms. These image files contain executable code, which provides support for the system, Ethernet<br />
ports, and network functions. For further details, see “Firmware Upgrade Files” on page 12-14<br />
• Bootup configuration file —The file contains bootup configuration information for the switch. The<br />
bootup configuration file stores the network configuration parameters. For further details, see “Bootup<br />
Configuration File” on page 12-14<br />
• Debug Configuration file — The debug configuration file stores the default debug configuration<br />
information. For further details, see “Debug Configuration File” on page 12-14<br />
• Script file —The script file consists of commands to be performed on the switch so that<br />
appropriate actions can be taken on the downloaded files. For further details, see “Script File” on<br />
page 12-15<br />
Instruction File<br />
The instruction file is the initial file required for automatic remote configuration process to occur. The<br />
instruction file is stored in the TFTP server with the .alu extension.<br />
The instruction file contains user information such as switch ID, file version, firmware version, image<br />
file names and location, configuration file (vcboot.cfg) name and location, script file name and location,<br />
FTP/SFTP server IP address, username and password to connect to the FTP/SFTP server.<br />
The TFTP server IP address and instruction filename details are received from the DHCP server by the<br />
DHCP client on the Omni<strong>Switch</strong>.<br />
The instruction file is downloaded from the TFTP server and stored in the /flash/working directory of the<br />
switch.<br />
Note.<br />
• If an error or failure occurs during the file transfer, the transfer process is retried up to three times. If<br />
file transfer and download are not successful, the automatic remote configuration process is halted and<br />
the switch is made available remotely using SSH.<br />
• All contents of the instruction file are stored in the switch log (swlog.log) file as evidence of the last<br />
Automatic Remote Configuration download.<br />
