Network Configuration Examples

Example 1: Single SP Switch Router Adapter card, single SP partition

In this configuration, a single SP Switch Router Adapter card is connected to a single SP partition. The IP address of the SP Switch network is 198.174.11. The partition of SP nodes is shown in the shaded area of Figure C-1.

Configuration requirements

•All network nodes (SP Switch Router Adapter card and SP processor nodes) must have the same IP net in the network portion of their IP address. In the example, this is 198.174.11.

•ARP is enabled on the SP Switch network to provide the most flexibility in assigning IP addresses

•If ARP is disabled on the SP Switch, the Host Offset value must be defined to all network nodes (SP Switch Router Adapter card and SP processor nodes), and the IP addresses assigned to the nodes must have host values that are determined by the host offset and switch port. Please refer to the RS/6000 SP Planning, Volume 2, Control Workstation and Software Environment manual for details.

If the network is 198.174.11.0 and the netmask is 255.255.255.0, then the IP address of the SP Switch Router Adapter card and any SP processor nodes must be between 198.174.11.1 and 198.174.11.254. The SP Switch Router Adapter card will not properly forward IP data to nodes that are assigned with an IP address that is not in this address range (those IP messages will most likely be forwarded to the default gateway).
