3.1 Static IP
3.1.1 Overview
In the Static IP mode, users have to manually specify all the parameters such as IP addresses of the
NEMO10, 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. Computers use IP addresses to identify and talk to each other on the network. Choose the
proper IP address which is unique and valid on the 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 NEMO10 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 NEMO10,
the connection is established directly from the NEMO10. 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
NEMO10 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,
please refer to the network administrator.
3.1.2 Static IP Configuration
To configure IP configuration parameters of the NEMO10, use set command as follows:
set ip static ip_address subnet_mask default_gateway + <CR>
where,
ip_address = IP address of the NEMO10
subnet_mask = Subnet mask
default_gateway = Default gateway IP address
Figure 3-1 shows IP configuration command example screen. To apply changes, users have to invoke
‘save’ and ‘reboot’ command after changing configuration.
