Configuring the IP Address Using ARP-Ping
Chapter 2 Configuring the IP Address 14
Configuring the IP Address Using ARP-Ping
Use this section to configure an IP address by manually updating a server’s ARP table and then pinging the Digi
device.
Note: 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.
Starting Point
This procedure assumes the following:
• That your Digi device supports this feature. See "Device Support: Digi Port Authority-Remote and ARP-Ping
for IP Address Configuration" on page 13.
• That your Digi device is connected to the Ethernet network
Procedure
1. Record the MAC address of the Digi device. It’s on the back 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 system:
arp -s 143.191.2.1 00-00-9d-22-23-60
4. Ping the Digi device using the IP address just assigned. The following is an example:
ping 143.191.2.1
The ping will probably time out before there is a response from the Digi device.
5. Wait a few seconds and then ping the Digi device again.
The Digi device replies to the ping, indicating that the IP address has been configured.
Configuring the Ethernet Interface from the Command Line
This section discusses how use the command line to configure an IP address, mask, and default gateway for Digi
One/PortServer TS 2/4’s Ethernet interface.
Manual Configuration Procedure
1. To ensure that the IP address you configure is permanent, turn DHCP off by entering the following command:
set config dhcp=off
2. To configure an IP address for the Ethernet interface, enter the following command:
set config ip=ip-address
where ip-address is the IP address for the Ethernet interface
Example
set config ip=191.143.2.154
3. To configure a subnetmask, enter the following command:
set config submask=mask
where mask is the subnet mask for this subnetwork
