  • Page 87 Appendix BOOTP Configuration Method (default) BOOTP (Bootstrap protocol) is a low-level protocol that provides configuration information to other nodes on a TCP/IP network with DOS, Microsoft Windows, Windows NT, Windows 9x, VMS, and HP-UNIX platforms. BOOTP configuration files let you automatically assign IP addresses to the ENI.

  • Page 88: Appendix B Using Bootp

    BOOTP Configuration Method (default) When BOOTP is enabled, the following events occur at power-up: The ENI broadcasts a BOOTP-request message containing its hardware address over the local network or subnet. The BOOTP server compares the hardware address with the addresses in its look-up table in the BOOTPTAB file. The BOOTP server sends a message back to the ENI with the IP address and other network information that corresponds to the hardware address it received.
  • Page 89 BOOTP Configuration Method (default) Edit the BOOTP Configuration File The boot-server configuration file, , is located in the directory. BOOTPTAB is an ASCII file that looks like: This file contains the information needed to boot the ENI. You must edit the file to include the name, IP address, and hardware address for each ENI you want the server to boot.
  • Page 90 BOOTP Configuration Method (default) 2. Make one copy of the configuration template for each ENI in your system. 3. Edit each copy of the template as follows: a. Replace “sigma1” with the name of the ENI. Use only letters and numbers; do not use underscores. b.

    BOOTP Configuration Method (default) Based on this configuration, the file looks like: Run the Boot Server Utility You can run either the DOS-based utility or the Windows-based BOOTP utility, but not both. If you have BOOTP enabled and the message appears, check the cabling connections and the BOOTP server system.

The DNI allows you to connect DF1 devices to DeviceNet networks. DF1 Full-Duplex DF1 is a standard (open) point-to-point communication protocol.
  • Page 94 Glossary Full-duplex A high-performance protocol that allows simultaneous two-way data transmission. For point-to-point applications only. IP (Internet Protocol) IP specifies the format of packets and the addressing scheme. Most networks combine IP with a higher-level protocol called Transport Control Protocol (TCP), which establishes a virtual connection between a destination and a source.
