DHCP is a protocol for dynamically assigning IP addresses to the devices on a
network. With dynamic addressing, a device can have a different IP address every
time it connects to the network. In some systems, the device's IP address can
even change while it is still connected. DHCP also supports a mix of static and
dynamic IP addresses.
Dynamic addressing simplifies network administration because the software
keeps track of IP addresses rather than requiring an administrator to manage the
task. This means that a new computer can be added to a network without the
hassle of manually assigning it a unique IP address. Many ISPs (Internet Service
Providers) use dynamic IP addressing for dial-up users.

By default, the DHCP service is disabled and you should 'enable' the DHCP
server explicitly for the service to become available.
The DHCP server in the OA-700 provides DHCP clients with an IP address along
with other network and boot information, based on the DHCP request received
from the client.
The major configurable objects in the DHCP component are the pools and
options. There is a global set of options and each pool can have its own set of
options configured. While processing a client's DHCP request the options will be
looked up in the pool to which the request is matched. If the pool specific options
are not configured, the global options for the VRF the pool belongs to will be
checked. If both of them are not configured, then the particular option will not be
returned in the response message.
