18 DHCP SERVER
18.1 DATA FROM DHCP
The phone has support for DHCP by which the following IP configuration data can be
provided:
• Own IP address, subnet mask and default gateway, received in the DHCP stan-
dard fields (1 and 3).
• The VLAN used for the phone can generally be set in option 132 or be part of
Option 43. If the phone’s configuration has another value than that of the option
value it will configure according to the Option 132 value and making a reboot.
• IP address to the software server. The path to the firmware to be downloaded
from the software server can also be provided as well as the protocol to be used.
The recommendation is to use DHCP option 66 (TFTP server name), but DHCP
option 60 (vendor class identifier) and option 43 (vendor specific information
field) can also be used.
The following examples show the different possibilities on how to use option 66,160 or
159 in order to get the IP address or host and its path to the software server. For http
and https it is possible to define the port. Default port for http is 80 and default port for
https is 443:
http://192.168.1.45
http://192.168.1.45/path
http://192.168.1.45:8080/path
http://srv.example.com/path
The default dhcp precedence order is 43, 160, 159, 66. So if the phone receives the
software server configuration in both option 66 and option 43, then option 43 takes
precedence over option 66.
If option 66 is already in use, it is possible to set the configuration server in either option
160 or 159 instead.
18.2 DHCP SETTINGS FOR OPTION 66
Enter the URL to the software server according to the example in 18.1 Data from DHCP
on page 63.
18.3 DHCP SETTINGS FOR OPTION 43 AND 60
DHCP option 60 (vendor class identifier) and option 43 (vendor specific information
field) can also be used to get the software server address and also to load a unique
configuration file dependent on telephone type.
The first step is to initiate option 60 for each telephone type:
