Configuring Automatic Updates using a DHCP or Linux BootP server
B
4. Restart the access point.
5. While the access point boots up, verify the access point:
• Obtains and applies the expected IP Address from the DHCP Server
• Downloads the firmware and configuration files from the TFTP Server and updates both as
required. Verify the file versions within the System Settings screen.
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.
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.
DHCP priorities
The following flowchart indicates the priorities used by the access point when the DHCP server is
configured for multiple options.
If the DHCP 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 DHCP Server is
configured for options 187 and 67 (for the firmware file) the access point uses the file name
configured for option 187. If the DHCP Server is configured for embedded and global options, the
embedded options take precedence.
