To set up an IP alias for the alternate IP address
The IP alias must be in the same network as the default IP address you want
the 3-DNS Controller to use. For example, on a UNIX workstation, you
might create one of the following aliases:
◆ If you want the unit to use the default IP address 192.168.1.245, then add
an IP alias to the machine you want to use to connect to the unit using the
following command:
ifconfig exp0 add 192.168.1.1
◆ If you want to use the default IP address 192.168.245.245, then add an IP
alias such as:
ifconfig exp0 add 192.168.245.1
On Microsoft Windows
®
or Windows NT
®
machines, you must use a static
IP address, not DHCP. Within the network configuration, add an IP alias in
the same network as the IP address in use on the unit. For information
about adding a static IP address to a Microsoft Windows operating system,
please refer to the vendor’s documentation.
Determining which default IP address is in use
After you configure an IP alias on the administrative workstation in the
same IP network as the 3-DNS Controller and you turn the system on, the
3-DNS software sends ARPs on the internal VLAN to see if the preferred
192.168.1.245 IP address is in use. If the address is appropriate for your
network and is currently available, the 3-DNS software assigns it to the
internal VLAN. You can immediately use it to connect to the unit and start
the Setup utility.
If the alternate network is present on the LAN, 192.168.245.0/24, or if the
node address 192.168.1.245 is in use, then the 3-DNS software assigns the
alternate IP address 192.168.245.245 to the internal VLAN instead.
Starting the utility from a web browser
When you start the utility from a web browser, you use the selected default
IP address as the application URL.
To start the Setup utility in a web browser
1. Open a web browser on a workstation connected to the same IP
network as the internal VLAN of the unit.
2. Type the following URL, where <default IP> is the IP address in
use on the 3-DNS internal VLAN.
https://<default IP>
3. At the login prompt, type root for the user name, and default for the
password.
The Configuration Status screen opens.
