IBM 9077 manual SP Switch ATM OC-12c SP Switch Connection

Configuration assumptions:

•The SP Switch Router ATM media card has been installed according to Section 4.3, “ATM OC-12c Configuration” on page 119 on both GRF routers and works properly.

•The SP Switch Router Adapter card has been installed according to Section 3.7, “Step-by-Step Media Card Configuration” on page 86 on both GRF routers and works properly.

•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 OC-12c media card’s port 00 connected to the GRF 400 ATM OC-12c media card’s port 00. The GRF 400 in turn is attached to the SP Switch of SP2, as shown in Figure 70 and Table 25 on page 224. The netmask on all interfaces is 255.255.255.0.
