Configuration assumptions:
•The SP Switch Router ATM media card has been installed according to Section 4.3, “ATM
•The SP Switch Router Adapter card has been installed according to Section 3.7,
•The SP Switch Router Adapter card and SP processor node Switch adapters are in the same IP subnet on the respective SP.
•ARP should be enabled on the SP Switch network to provide the most flexibility in assigning IP addresses (strongly recommended!).
•If ARP is disabled on the SP Switch network, the IP addresses assigned to the nodes must be determined by the switch node numbers.
Note: The SP Switch Router Adapter card will not properly forward IP data to nodes assigned with an IP address that is in another subnet.
Configuration:
In this scenario, we have the SP Switch of SP21 connected to the GRF 1600. The GRF 1600 has its ATM
