Understanding Address Configuration for Connected Devices
In Figure A-2, two devices are connected to the OnBoard. The public Ethernet
port on the OnBoard has a public IP address of 203.1.2.3. The administrator
plans to assign the following:
• Two private IP addresses within the 192.168.49.0 network range to the
devices on the OnBoard’s private network: 192.168.49.60 and
192.168.49.61,
• A third private IP address within the same range to the OnBoard:
192.168.49.254.
Figure A-3 shows the values the administrative user would enter in the Web
Manager to configure the private subnet shown in Figure A-2.
Figure A-3:
Private Subnet Configuration Example
Figure A-3 shows the following values entered in the dialog that appears
when the “Add Subnet” button is clicked on the Network
→
Private subnets
screen:
• Private subnet name: privnet
• OnBoard side IP address: 192.168.49.254
• Subnet netmask: 255.255.255.0.
The private subnet address derived from the configuration in Figure A-3 is
192.168.49.0. For this network IP address, the conventional broadcast address
is 192.168.49.255. Because the OnBoard’s address is 192.168.49.254, the
administrator can assign any remaining IP address between 192.168.49.1 and
192.168.49.253 when configuring a connected device.
The following figure shows these values: Private subnet “privnet,” and Device
IP address 192.168.49.61 assigned to the device rack1_dev2_compaq_ilo on
