Appendix E: Configure DHCP Options
IPBS/IPBL include a DHCP client which allows the IP interface to be configured from a DHCP
server. In addition to that, IPBS/IPBL also allow configuring a number of settings via special
DHCP vendor options.
E.1 System Requirements
To use vendor specific DHCP options, a DHCP server that supports such options is required.
Most popular DHCP server implementations such as the Microsoft Windows DHCP service and
the Linux dhcpd do so.
E.2 Configuration
For the DHCP server to support vendor specific options, the options must be made known to the
server. Consult the accompanying documentation which comes with your DHCP server
implementation how to do this.
E.3 Supported Options
Name Data type Array Code Meaning How to code
H323
gatekeeper
IP address Yes 200 Defines the IP address
of both the primary and
the alternate gatekeeper
for the device. This is
only required, if
gatekeeper discovery is
not feasible
This is an array of IP
addresses. Put the
primary gatekeepers IP
into the first entry, the
alternate gatekeepers IP
into the second entry.
Further entries are
ignored.
H323
gatekeeper
id
String No 201 The gatekeeper id of
the gatekeeper the
device likes to register
with. Usually required
only if several
gatekeepers are running
and a particular one
must be chosen during
gatekeeper discovery
Type the gatekeeper id
as configured in the
gateway or PBX
configuration into the
string field.
POSIX TZ String No 202 Defines both the time
zone and the daylight
saving time
information.
This option is in fact
identical to the standard
DHCP option number
88 (TZ). However,
various DHCP servers
do not support this
option, so it is provided
as a redundant vendor
specific option. If your
DHCP server supports
option 88, the vendor
specific option is not
needed.
