LAN Brick

How to configure a LAN Brick™ via a boot file

Use of LAN Brick boot file

You can use the boot file to provide the LAN Brick with default values for; IP Address, Subnet Mask, and Gateway Address. This way the LAN Brick does not  require the presence of a BOOTP server (except for the first time)

Requirements:

  • A TFTP Daemon must be installed.
  • The BOOTP database entry for the LAN Brick must include a boot file definition, that is bf=<bootfile path>.
  • The boot file must reside on the same disk partition as the BOOTPTAB file.

Example LAN Brick boot file

Below is a listing of a typical LAN Brick boot file (lanbrick.cfg). 129.1.71.100 is the IP Address, 255.255.0.0 is the subnet mask, and 129.1.71.0 is the gateway address. i-data7913 is a mandatory boot file id.


 



i-data7913

default 129.1.71.100,255.255.0.0,129.1.71.0

The IP Address, subnet mask, and gateway address need not match those specified in the BOOTPTAB entry. If you for example intend to move the LAN Brick to another LAN environment (with no BOOTP server) you should specify the new IP Address etc. in the boot file, while maintaining the current IP Address etc. in the entry in the BOOTP server's database (BOOTPTAB). Refer to the Installation & Operator's Guide for information on LAN Brick boot file syntax and use of the micro code upgrade facility.

Example entry in BOOTP server database
