SP Switch Router UNIX tools

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.
