Configuring Automatic Updates using a DHCP or
Linux BootP Server
This section provides specific details for configuring either a DHCP or Linux BootP Server to send
firmware or configuration file updates to an access point.
The AutoUpdate feature updates the access point firmware and/or configuration automatically when
the access point is reset or does a DHCP request. 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.
The firmware is automatically updated each time firmware versions are found to be different between
what is running on the access point and the firmware file that resides on the server. The configuration
file is automatically applied when the configuration filename is found to be different between what
resides on the access point and the filename residing on the server or when the configuration version is
found to be different between what resides on the access point and the configuration version residing
on the server.
The configuration version can be modified in the text file to cause the configuration to be applied when
required. The parameter name in the file is “cfg-version-1.1-01”. The access point only checks the two
characters after the third hyphen (01) when making a comparison. Change the last two characters to
update the configuration. The two characters can be alpha-numeric.
