Configuring automatic updates using a DHCP or Linux BootP server
B
NOTE
The bf option prefixes a forward slash (/) to the configuration file name. The forward slash may
not be supported on Windows based SFTP Servers.
3. Copy the firmware and configuration files to the appropriate directory on the SFTP Server.
By default, auto update is enabled on the access point (since the LAN Port is a DHCP Client,
out-of-the-box auto update support is on the LAN Port).
4. Restart the access point.
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 SFTP 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 sftp 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 SFTP root directory from the
fully qualified configuration file name to obtain a relative file name. For example, if using
bf=/opt/sftpdir/sftp/dist/ap.cfg and T136="/opt/sftpdir", the config file name is
sftp/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:
