Configuring BOOTP/TFTP
The AI232 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 AI232 starts, it determines if the following conditions are met before using
BOOTP to find IP address information:
z AI232 is in standalone mode
z The IP address is not set.
If both of these conditions are met, AI232 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, AI232 will resume its boot process.
The following events occur when AI232 attempts to download a configuration file from
the TFTP server:
z Once the IP address information has been correctly configured from the BOOTP
reply, AI232 will attempt to contact a TFTP server only if the TFTP server IP
address and configuration filename were received by the BOOTP reply.
z AI232 will try to download the configuration file from the TFTP server once every
60 seconds for a maximum of 10 retries.
z If no valid configuration file is downloaded from the TFTP server after 10 retries,
AI232 will remove the previously configured IP address information from the
BOOTP server and completely restart the BOOTP process.
z If at any time the local configuration file stored on flash is changed by a user,
AI232 will stop attempting to contact the TFTP server.
z If a valid configuration is successfully downloaded from the TFTP server, AI232
will update the current configuration with the downloaded file.
