5 While the Access Point boots, verify the Access Point:
Sends a true BootP request.
●
Obtains and applies the expected IP Address from the BootP Server.
●
Downloads both the firmware and configuration files from the TFTP Server and updates them as
●
required. Verify the file versions within the System Settings screen.
Whenever a configuration file is specified, the Access Point will tftp the config file, parse it and use the
firmware file name in the config file.
If T136 is provided by the server, the Access Point strips off the TFTP root directory from the fully
qualified configuration file name to obtain a relative file name. For example, if using
bf=/opt/tftpdir/ftp/dist/ap.cfg and T136="/opt/tftpdir", the config file name is
ftp/dist/ap.cfg. T136 is only used for this purpose. It is NOT used to append to the config file name or
the firmware file name. If T136 is not specified, the Access Point uses the entire bf field as the config file
name.
NOTE
The update process is conducted over the LAN or WAN port depending on which Server responds first to
the Access Point's request for an automatic update.
NOTE
If the firmware files are the same, the firmware will not get updated. If the configuration file name matches
the last used configuration file on the Access Point or if the configuration file versions are the same, the Access
Point configuration will not get updated. The LAN Port needs to be configured as a BootP client. There's no BootP
support on the WAN Port. The WAN supports only DHCP.
BootP Priorities
The following flowchart displays the priorities used by the Access Point when the BootP server is
configured for multiple options:
If the BootP Server is configured for options 186 and 66 (to assign TFTP server IP addresses) the Access
Point uses the IP address configured for option 186. Similarly, if the BootP Server is configured for
options 188 and 129 (for the configuration file) the AP uses the file name configured for option 188.
