6. On the CWS of SP2 check if the SP Switch Router Adapter card is
configured. See if the SP Switch Router Adapter card shows up green in
perspectives or enter
needed.
7. Issue some commands to check the connection:
ping
On the chosen SP2 nodes,
example:
root@sp2n09:/ ping 10.2.1.1
PING 10.2.1.1: (10.2.1.1): 56 data bytes
64 bytes from 10.2.1.1: icmp_seq=0 ttl=255 time=0 ms
64 bytes from 10.2.1.1: icmp_seq=1 ttl=255 time=0 ms
^C
----10.2.1.1 PING Statistics----
2 packets transmitted, 2 packets received, 0% packet loss
round-trip min/avg/max = 0/0/0 ms
On node 10 in SP21,
SP2, for example:
root@sp21n10:/ ping 192.168.13.9
PING 192.168.13.9: (192.168.13.9): 56 data bytes
64 bytes from 192.168.13.9: icmp_seq=0 ttl=255 time=0 ms
64 bytes from 192.168.13.9: icmp_seq=1 ttl=255 time=0 ms
^C
----192.168.13.9 PING Statistics----
2 packets transmitted, 2 packets received, 0% packet loss
round-trip min/avg/max = 0/0/0 ms
If these commands fail, check routing settings again. If everything is
ping
as it should be, try to
SP Switch Router Adapter card to ascertain the failing part:
ping 192.168.13.4 (on chosen processor nodes in SP2)
ping 10.2.1.2 (on node 10 in SP21)
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 4.4, "FDDI Configuration" on page
121) and also the network adapters in the nodes.
Performance:
To get a rough overview of the data transfer rates that can be achieved in
such a scenario, we performed the following tests:

program developed by T.C. Slattery, USNA, improved by Mike Muuss,
