226 IBM 9077 SP Switch Router: Get Connected to the SP Switch

5. Check for correct routing entries on all nodes in SP2:

6. Issue some ping commands to check the connection:

On the SP21 nodes, ping the SP Switch interface of nodes in SP2; on

nodes in SP2 ping the SP Switch interface of nodes in SP21.

If these ping commands fail, check routing settings again. If everything is

as it should be, try to ping the SP Switch Router ATM media card or the SP

Switch Router Adapter card to find the failing part:

ping 192.168.14.4 (on SP21 processor nodes)

ping 192.168.13.4 (on SP2 processor nodes)

ping 10.20.30.1 and ping 10.20.30.2 (on both GRF 400 and GRF 1600)

If any errors occur, check cabling, the configuration of the SP Switch

Router media cards (see Section 3.7, “Step-by-Step Media Card

Configuration” on page 86 and Section 4.3, “ATM OC-12c Configuration”

on page 119) and the Switch adapters in the SP nodes.
