CyberData 10935 Operation Manual page 66

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;
subnet 10.0.0.0 netmask 255.0.0.0 {
Autoprovisioning
Instead of using DHCP to provide the autoprovisioning tftp server address, you can specify an
Server (IP Address)
address manually.
Autoprovisioning When the device is set to autoprovision either after a period of time, or when idle, or at a time of day,
Autoupdate
the device will do the following:
•
•
•
Autoprovisioned An Autoprovisioned firmware upgrade only happens after a reboot, will take roughly three minutes,
Firmware Upgrades
and the web page will be unresponsive during this time.
The 'FirmwareVersion' value in the xml file must match the version stored in the 'FirmwareFile'.
<FirmwareVersion>v6.5.1</FirmwareVersion>
<FirmwareFile>651-intercom-uImage</FirmwareFile>
If these values are mismatched, the board can get stuck in a loop where it goes through the following
sequence of actions:
1. The board downloads and writes a new firmware file.
2. After the next reboot, the board recognizes that the firmware version does not match.
3. The board downloads and writes the firmware file again.

Re-download the autoprovisioning file.
Compare this new file to the one downloaded on boot, and if it finds differences, force a system
reset.
After rebooting, the board will configure itself according to this new file.
