As illustrated in Figure 4.1, the dedicated Ethernet ports on SPs and on other supported types of devices are connected to the private Ethernet ports on the OnBoard appliance. Each connected device’s dedicated Ethernet port needs an internal IP address assigned on the OnBoard and configured for the interface. By implementing an addressing scheme, the administrator creates a pool of internal addresses that can be assigned to the devices’ dedicated Ethernet ports and configured for the device on the OnBoard appliance side.
While implementing the addressing scheme, the administrator assigns to the OnBoard appliance itself one or more IP addresses in addition to the OnBoard appliance’s public IP address. The OnBoard appliance’s private IP address or addresses are used by the following:
Figure 4.2 shows some example IP addresses assigned.
See Address configuration for connected devices for the details needed for planning and implementing IP addresses.
