7.Issue some ping commands to check the connection:
On the SP2 nodes, ping the SP Switch interface of any node in SP21:
root@sp2n01:/ ping 192.168.14.1
PING 192.168.14.1: (192.168.14.1): 56 data bytes
64 bytes from 192.168.14.1: icmp_seq=0 ttl=254 time=1 ms
64 bytes from 192.168.14.1: icmp_seq=1 ttl=254 time=1 ms ^C
2 packets transmitted, 2 packets received, 0% packet loss
On the SP21 nodes, ping the SP Switch interface of any node in SP2:
root@sp21n01:/ ping 192.168.13.1
PING 192.168.13.1: (192.168.13.1): 56 data bytes
64 bytes from 192.168.13.1: icmp_seq=0 ttl=254 time=1 ms
64 bytes from 192.168.13.1: icmp_seq=1 ttl=254 time=1 ms ^C
2 packets transmitted, 2 packets received, 0% packet loss
If these ping commands fail, check routing settings again. If everything is as it should be, try to ping both SP Switch Adapter cards to find the failing part:
ping 192.168.13.16 (on SP2 nodes) ping 192.168.14.4 (on SP21 nodes)
If any errors occur, check cabling, the configuration of the SP Switch Router cards (see Section 3.7,
Performance:
To get a rough overview of the data transfer rates that can be achieved between the SPs, we again used ftp to transfer several 300MB files from different nodes in SP2 to several nodes in SP21. We sent these files to /dev/null to eliminate any hard disk influence on the receiver side.
The requisites for this test are the same as described in Section 5.1.4.1, “SP Switch - FDDI Connection without Bridging” on page 174. We started ftp transfers on all available nodes of SP2 and on some nodes of SP21.
