2.3.2.1 Autoprovisioning
Enable With autoprovisioning enabled, the board will get it's configuration from a remote TFTP server on
Autoprovisioning
startup or periodically on a scheduled delay. These autoprovisioned values will take precedence
Option
over values stored in the boards own non-volatile memory. The board gets it's autoprovisioning
information from an XML-formatted file hosted from a TFTP server. CyberData will provide a
template for this XML file and the user can modify it for their own use.
Get On the webpage you can specify an address where the board will look for autoprovisioning
Autoprovisioning
information or have it use an address supplied by your DHCPD server through option 66 (tftp-
from DHCP
server-name) or 150.
Autoprovisioning If autoprovisioning is turned on and the autoprovisioning autoupdate value is something other than
Autoupdate
0 minutes, a service is started on startup that will wait the configured number of minutes and then
try to re-download it's autoprovisioning file. It will compare it's previously autoprovisioned file
with this new file and if there are differences, it will reboot the board.
Autoprovisioning On boot the device will go to it's autoprovisioning server address and try to read a configuration
Server (IP Address)
file. The board will look for a configuration file named <mac address>.config. For example:
0020f7350185.config
The mac address has to be all lower case.
It's possible to only configure a subset of all configuration options using autoprovisioning. Options
not autoprovisioned will default to the values stored in the on board memory.
To set up a Linux DHCPD server to serve autoprovisioning information (in this case using both
option 66 and 150), here's an example dhcpd.conf:
# dhcpd.conf
#
# Configuration file for ISC dhcpd (see 'man dhcpd.conf')
#
ddns-update-style ad-hoc;
option option-150 code 150 = ip-address;
