Options for Configuring the IP Address and Mask
Chapter 2 Configure the IP Address 11
The next step in configuring your Digi product is to configure an IP address
and access the device for more advanced configurations. You must set the
initial IP before you can use the web interface. Once the IP is set, the
device can be accessed through the web interface and any changes made
including changing the IP address.
Important: Before you configure your device server, write down the MAC
Address located on the bottom of your product. For Digi One IA and
Digi One SP products, the MAC address also serves as the serial number.
Options for Configuring the IP Address and Mask
The device server IP address can be configured using the following
methods:
• From the command line, using the “set config” command. See the Digi
One and PortServer TS Family Command Reference for more details
including syntax and supported devices.
• By updating the ARP table on a server and then pinging the Digi device
(called ARP-Ping, see "Configure the IP Address Using ARP-Ping" on
page 11).
• Using a DHCP server (see "Configure an IP Address using DHCP and
RARP" on page 12.)
• Using a RARP server (see "Configure an IP Address using DHCP and
RARP" on page 12.)
The IP address and mask can also be changed using the web interface,
but not for initial IP address configuration.
Configure the IP Address Using ARP-Ping
An IP address can be configured by manually updating a server’s ARP
table and then pinging the Digi device.
The ARP-Ping command assigns the IP address you designate but also
assigns default subnet mask and gateway addresses. It is necessary to
change the subnet mask and gateway addresses.
This procedure assumes that your Digi device is connected to the Ethernet
network.
1. Record the MAC address of the Digi device. The MAC address is on the
label side (bottom) of the unit.
2. Access a server on the same subnet as the Digi device.
3. Manually update the server’s ARP table using the Digi device’s MAC
address and the IP address you want assigned to the Digi device. The
following is an example of how this is done on a Windows NT 4.0 sys-
tem:
arp -s 191.168.2.2 00-00-9d-22-23-60
