DHCP (Dynamic Host Configuration Protocol) allows you to dynamically and
automatically assign IP address settings to hosts on your network.. The DHCP Setup field
determines what mode of DHCP support the Prestige should use. If it is set to
None
,
DHCP will not be used. If it is set to
Server
, the Prestige will act as a DHCP server,
capable of automatically assigning IP addresses to Windows 95, Windows NT and other
systems that support the DHCP client.
Important: Do not set this field to ‘Server’ if there is already a DHCP server on your
net.
DHCP can assign IP addresses to hosts dynamically instead of requiring that each system
have a fixed IP address. IP addresses are allocated from a block of addresses called the
Client IP Pool.
4.4.3. TCP/IP Setup
Enter the IP address of the Prestige in dotted decimal notation (four 8-bit numbers,
between 0 and 255, separated by periods), the default is
192.168.1.1 . Please note that
every machine on the TCP/IP network must have a unique IP address. An IP address
consists of two parts, the network ID and the host ID. The IP Subnet Mask is used to
specify the network ID portion of the address, expressed in dotted decimal notation. The
Prestige automatically calculates this mask based on the IP address that you assign. Unless
you have special need for subnetting, use the default subnet mask calculated by the Prestige.
The RIP Direction parameter determines how the Prestige handles RIP (Routing
Information Protocol). If set to
Both
(default), the Prestige will broadcast its routing table
on the LAN and incorporate RIP broadcasts by other routers into its routing table. If set to
In Only
, the Prestige will not broadcast its routing table on the LAN, if set to
Out Only
,
the Prestige will broadcast its routing table but ignores any RIP broadcast packets that it
receives. If set to
None
, the Prestige will not participate in any RIP exchange with other
routers. The RIP Version determines what versions of RIP the router sends. Choices are:
◊
RIP-1 The router accepts and sends RIP version 1 messages only.
◊
RIP-2B The router accepts RIP-1 and RIP-2 messages (both broadcast and
multicast)and sends RIP-2 messages in broadcast format.
◊
RIP-2M The router accepts RIP-1 and RIP-2 messages (both broadcast and
multicast) and sends RIP-2 messages in multicast format.
Unless there are routers in your environment, that do not understand RIP-2 packets, you
should probably set this field to RIP-2B. Refer to Chapter 8 for further discussion on
TCP/IP Configuration.
