Introduction

A valid IP address of the device server needs to be assigned before it starts to work in the user's network envi-
ronment. A network system administrator may provide the user with this IP address setting information for
the network. The IP address must be unique within the network. Otherwise, the device server will not have a
valid connection to the network.
Users can choose the desired IP mode out of the two IP operating modes, i.e., Static IP and DHCP. The fac-
tory default IP mode is DHCP mode.
Basic set command usage for IP configuration is as follows:
set ip ipmode par1 par2 ...
where,
ipmode: 'static' for Static IP / 'dhcp' for DHCP
parameters:
if ipmode = static,
par1 = IP address, par2 = subnet mask, par3 = gateway
if ipmode = dhcp,
no parameters required

Static IP

In the Static IP mode, users have to manually specify all the parameters such as IP addresses of the device server,
valid subnet mask and the default gateway IP address.
IP address is an identification number assigned to a computer as a permanent address on the network. Comput-
ers use IP addresses to identify and talk to each other on the network. Choose a proper IP address which is
unique and valid for your network environment.
A subnet represents all the network hosts at one geographic location, in one building, or on the same local area
network. When there is any outgoing packet over the network, the device server will check whether the desired
TCP/IP host, specified in the packet, is on the local network segment with the help of the subnet mask. If the
address is proven to be on the same network segment as the device server, the connection is established directly
from the device server. Otherwise, the connection is established through the given default gateway.
A gateway is a network point that acts as an entrance to another network. Usually, the computers that control
traffic within the network or at the local Internet service provider are gateway nodes. The device server needs to
know the IP address of the default gateway computer in order to communicate with the hosts outside the local
network environment. For correct information on the gateway IP address, refer to the network administrator.
