Notes:
•
Typically, IP addressing at the customer site is done by DHCP.

33.1.4 DHCP-based Provisioning
This method is similar to the setup described in Local Configuration Server with
BootP/TFTP on page 391, except that DHCP is used instead of BootP. A third-party DHCP
server can be configured to automatically provide each device, acting as a DHCP client,
with a temporary IP address so that individual MAC addresses are not required. The DHCP
server can provide additional networking parameters such as subnet mask, default
gateway, primary and secondary DNS server, and two SIP server addresses. These
network parameters have a time limit, after which the device must 'renew' its lease from the
DHCP server.
The device can use a host name in the DHCP request. The host name is set to acl_nnnnn,
where
nnnnn denotes the device's serial number. The serial number is the last six digits of
the MAC address converted to decimal representation. In networks that support this feature
and if the DHCP server registers this host name to a DNS server, you can access the
device (through a Web browser) using the URL, http://acl_<serial number> (instead of
using the device's IP address). For example, if the device's MAC address is 00908f010280,
the DNS name is acl_66176.
Notes:
•
Throughout the DHCP procedure, make sure that the BootP/TFTP program
(AcBootP utility) is deactivated; otherwise the device receives a response from the
BootP server instead of the DHCP server. Typically, after the device powers up, it
attempts to communicate with a BootP server. If a BootP server does not respond
and DHCP is enabled, the device attempts to obtain its networking parameters
from the DHCP server.
•
When using DHCP to acquire an IP address, the Interface table, VLANs and other
advanced configuration options are disabled.
•
For more information on DHCP, see BootP Request and DHCP Discovery upon
Device Initialization on page 389.
•
For additional DHCP parameters, see ''DHCP Parameters'' on page 483.

To enable the device as a DHCP client:
1. Open the Application Settings page ( Configuration tab > System menu >
Application Settings ).
Figure 33-2: Enabling DHCP - Application Settings Page
2. From the 'Enable DHCP" drop-down list, select Enable .
3. Click Submit .
4. To activate the DHCP process, reset the device.
The following shows an example of a configuration file for a Linux DHCP server
(dhcpd.conf). The devices are allocated temporary IP addresses in the range 10.31.4.53 to
