Determining that TCP/IP routing is configured properly between the SP system and the SP
Switch Router is another task for a system administrator. This section details some commands
that can be useful in performing this task. For more information on managing the SP Switch
Router network data, please see the sections of the IBM PSSP Administration Guide that deal
with managing extension nodes.
ping
This standard tool generates and receives ICMP/IP echo request and reply messages. It is used
to test connectivity to a specific interface or to a host such as the SP. The version running on the
SP Switch Router is modified for use with media card protocols.
The most common use of ping is to use it from an SP standard node to determine if you have a
path to your SP Switch Router Adapter on the SP Switch network. This is necessary if you are
to reach or be reached by external networks that the SP Switch Router can access. From an SP
standard node, you can ping the IP address for the SP dependent node that corresponds to the
SP Switch Router Adapter. This IP address can be obtained by using the host command if you
have domain host name resolution configured in your network. If not, then this address is the
address associated with the switch network for that node, and not the address that would be
associated with the administrative network for nodes in your SP.
The following example shows how you might use host and ping to verify your path to the SP
Switch Router Adapter on an SP node named
sp_n3 . The SP dependent node in the same SP
system is sp_sn2 .
[sp_n3][/]> host sp_sn2
sp_sn2.ppd.pok.ibm.com is 129.40.85.130
[sp_n3][/]> ping 129.40.85.130
PING 129.40.85.130: (129.40.85.130): 56 data bytes
64 bytes from 129.40.85.130: icmp_seq=0 ttl=255 time=0 ms
64 bytes from 129.40.85.130: icmp_seq=1 ttl=255 time=0 ms
64 bytes from 129.40.85.130: icmp_seq=2 ttl=255 time=0 ms
----129.40.85.130 PING Statistics----
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max = 0/0/0 ms
[sp_n3][/]>
In this example, note the difference between sp_nX host names that refer to the Ethernet IP
address of a node, and the sp_snX host names that refer to the switch network IP address of a
node.
Refer to the GRF Reference Guide for other ping examples.
route
Static routing can be configured by using either the UNIX route command or the SP Switch
Router grroute command. Routing is the primary function of a router that allows IP traffic
from one network to reach another network. The SP Switch Router and the SP Switch Router
Adapter card support both static and dynamic IP routing.
