Instruction File
The instruction file is the initial file required for automatic remote configuration process to occur. The
instruction file is stored in the TFTP server with the .alu
extension.
The instruction file contains user information such as switch ID, file version, firmware version, image file
names and location, configuration file
(vcboot.cfg) name and location, script file name and location, FTP/
SFTP server IP address, username and password to connect to the FTP/SFTP server.
The TFTP server IP address and instruction filename details are received from the DHCP server by the
DHCP client on the OmniSwitch.
The instruction file is downloaded from the TFTP server and stored in the /flash/working directory of the
switch.
Notes.
• If an error or failure occurs during the file transfer, the transfer process is retried up to three times. If
file transfer and download are not successful, the automatic remote configuration process is halted and
the switch is made available remotely using SSH.
• All contents of the instruction file are stored in the switch log (swlog.log) file as evidence of the last
Automatic Remote Configuration download.
