2.4.12.1 Autoprovisioning

Autoprovisioning

File

It is not necessary to set every option found in the autoprovisioning template. As long as the XML is

valid, the file can contain any subset. Options not autoprovisioned will default to the values stored in

the on board memory. For example if you only wanted to modify the device name, the following

would be a valid autoprovisioning file:

<?xml version="1.0" encoding="utf-8" ?>

<DeviceName>auto Intercom</DeviceName>

</MiscSettings>

</specific>

Get

Autoprovisioning

from DHCP

When this option is checked, the device will automatically fetch its autoprovisioning server address

from the DHCP server. The device will use the address specified in OPTION 150 (TFTP-server-

name) or OPTION 66. If both options are set, the device will use OPTION 150.

Refer to the documentation of your DHCP server for setting up OPTION 150.

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 {

max-lease-time 120;

default-lease-time 120;

option routers 10.0.0.1;

option subnet-mask 255.0.0.0;

option domain-name "voiplab";

option domain-name-servers 10.0.0.1;

option time-offset -8; # Pacific Standard Time

option tftp-server-name "10.0.0.254";

option option-150 10.0.0.254;

range 10.10.0.1 10.10.2.1;}

Autoprovisioning

Server (IP Address)

Instead of using DHCP to provide the autoprovisioning tftp server address, you can specify an

address manually.

Autoprovisioning

Autoupdate

When the device is set to autoprovision either after a period of time, or when idle, or at a time of day,

the device will do the following:

• Re-download the autoprovisioning file.

• Compare this new file to the one downloaded on boot, and if it finds differences, force a system

reset.
