Configuring BOOTP/TFTP

The AI296 configuration can be automatically downloaded from a TFTP server when the card is in standalone mode and has BOOTP information stored in AI198 Menu 10. For more information about BOOTP configuration, refer to “Configuring the BOOTP Table” in the AI198 Common Logic Controller System Manager/User’s Manual.

When AI296 starts, it determines if the following conditions are met before using BOOTP to find IP address information:

zAI296 is in standalone mode

zThe IP address is not set.

If both of these conditions are met, AI296 attempts to contact a BOOTP server until it obtains valid IP address information or the IP address is set by a user with the

ip init shell command. When an IP address has been obtained either by BOOTP or through the ip init command, AI296 will resume its boot process.

The following events occur when AI296 attempts to download a configuration file from the TFTP server:

zOnce the IP address information has been correctly configured from the BOOTP reply, AI296 will attempt to contact a TFTP server only if the TFTP server IP address and configuration filename were received by the BOOTP reply.

zAI296 will try to download the configuration file from the TFTP server once every 60 seconds for a maximum of 10 retries.

zIf no valid configuration file is downloaded from the TFTP server after 10 retries, AI296 will remove the previously configured IP address information from the BOOTP server and completely restart the BOOTP process.

zIf at any time the local configuration file stored on flash is changed by a user, AI296 will stop attempting to contact the TFTP server.

zIf a valid configuration is successfully downloaded from the TFTP server, AI296 will update the current configuration with the downloaded file.
