3 Troubleshooting
This chapter provides guidelines for troubleshooting HP-UX 11i v3 IPv6 transport. It
contains a troubleshooting overview and diagnostic flowcharts.
Troubleshooting Overview
Troubleshooting problems on HP-UX 11i v3 IPv6 transport, can involve a variety of
hardware and software components. The problem impacting your system might originate
in another part of the network.
Because HP-UX 11i v2 IPv6 supports an IPv6/IPv4 Dual Stack, test IPv4 connectivity
before testing IPv6 connectivity. Refer to the HP-UX LAN Administrator’s Guide (available
at http://www.docs.hp.com) for IPv4 troubleshooting advice.
If you are still unable to identify your problem, proceed to the troubleshooting flowcharts.
The troubleshooting flowcharts provide logical steps to follow. Use the diagnostic
flowcharts provided in this chapter to verify your assumptions and to try to identify whether
the problem is with HP-UX 11i v3 IPv6 transport or router configuration.
Diagnostic Flowcharts
Below is a summary of the types of network tests in the diagnostic flowcharts. To diagnose
your problem, first verify the connections and configuration on your system (Flowcharts
1 through 5). If this does not solve your problem, use Flowchart 6 to test and/or verify
connectivity with a remote system.
Flowchart 1 Transport Level Test using Internet Services
Flowchart 2 Network Connectivity Test
Flowchart 3 Name Services Test
Flowchart 4 Interface Test
Flowchart 5 Interface Test (continued)
Flowchart 6 Router Remote Loopback Test
Transport Level Loopback Test using Internet Service: Verifies round-trip communication
between Transport Layers on the source and target host using telnet.
Network Connectivity Test: Verifies round-trip communication between Network Layers
on the source and target host using the ping(1M) diagnostic.
Name Services Test: Verifies host name and IPv6 address resolution.
Interface Test: Verifies the configuration of the network interface on a host using the
lanscan, and ifconfig commands.
Router Remote Loopback Test: Verifies the connection between local and remote nodes
through IPv6 routers using the ping and netstat commands.
