Assigning the IP Address
Getting Started
3-2
A DHCP-assigned IP address does not appear in the Device Server’s configuration screen
(Setup Menu). You can, however, determine your Device Server’s DHCP-assigned IP
address in Monitor Mode. When you enter Monitor Mode from the serial port with network
connection enabled and issue the NC (Network Connection) command., you will see the
Device Server’s IP configuration. (For more information about Monitor Mode, see the
Troubleshooting appendix.)
DHCP Name
A DHCP name is a unique identifier used for managing multiple DHCP hosts on a network.
Your Device Server ships with a default DHCP name of Cxxxxxx, where the xxxxxx is the
last six digits of your Device Server’s MAC address. You can change the DHCP name (up
to 8 characters) from the Server Configuration option on the Setup Menu.
The name can be changed to LTXdd, where 0.0.0.dd is the IP address assigned (dd should
be a number between 1 and 99). For example, if the IP address is set to 0.0.0.5, the resulting
DHCP name is LTX05.
Figure 3-1: Server Configuration Option
Note:
If you are rolling out a large number of Device Servers and do not
want to track them by their MAC address, change the DHCP name to
LTX##, where ## is the IP address of your Device Server. For
example, if the IP address is 192.169.11.17, then the DHCP name for
the Device Server will be LTX17.
The Device Server’s IP address must be configured before a network connection is
available. If the IP address was not set automatically via DHCP, set it now using one of the
following methods.
Auto IP
AutoIP is an alternative to DHCP that allows hosts to automatically obtain an IP address in
smaller networks that may not have a DHCP server. A range of IP addresses (from
169.254.0.1 to 169.254.255.1) has been explicitly reserved for AutoIP-enabled devices.
The range of Auto IP addresses is not intended to be used over the Internet.
If your Device Server cannot find a DHCP server, and you have not manually assigned an
IP address to it, then it automatically selects an address from the AutoIP reserved range.
Then, your device sends out an (ARP) request to other nodes on the same network to see
whether the selected address is being used. If the selected address is not in use, then the
Device Server uses it for local subnet communication.
If another device is using the selected IP address, the Device Server selects another address
from the AutoIP range and reboots itself. After reboot, the Device Server sends out another
ARP request to see if the selected address is in use, and so on.
