4.0 Configuration
DHCP: Dynamic Host
Configuration Protocol
may be used by
networked devices
(Clients) to obtain unique
network addresses from a
DHCP server.
Advantage:
Ensures unique IP
addresses are assigned,
from a central point
(DHCP server) within a
network.
Disadvantage:
The address of a
particular device is not
‘known’ and is also
subject to change.
STATIC addresses must
be tracked (to avoid
duplicate use), yet they
may be permanently
assigned to a device.

The option is used to enable or disable the DHCP service for
devices connected to the LAN Port and devices connected
through a Wireless connection. This includes VIP connected as
clients and other wireless devices such as 802.11 connections.

4.2.3 Network > DHCP
DHCP Configuration > LAN DHCP
A VIP4G may be configured to provide dynamic host control protocol (DHCP) service to all
attached (either wired or wireless (WiFi)-connected) devices. By default the DHCP service is
enabled, so devices that are connected to the physical Ethernet LAN ports, as well as any
devices that are connected by WiFi will be assigned an IP by the VIP4G.
Prior to enabling this
service, verify that there
are no other devices -
either wired (e.g. LAN) or
wireless (e.g. another VIP
Series unit) with an active
DHCP SERVER service.
(The Server issues IP
address information at the
request of a DHCP Client,
which receives the
information.)
