If you are using IPv6 for network connectivity, you can use several
of the same troubleshooting tools as you do for IPv4. For instance, you can
use trace route and Ping to test connections and routes for both types of
networks. In addition, you can use the Netstat and communications trace functions
for IPv6.
Remember these tips when troubleshooting problems that are specific
to IPv6:
- Ensure that your Ethernet line is configured and
active. To check the status of lines that are configured on the
system, follow these steps:
- In System i® Navigator,
expand .
- In the right pane, find the line that should be configured for
IPv6 and check the Status column. If the line does not appear in the list,
you must configure a line for IPv6 either by manually configuring interfaces
on an existing line or by using IPv6's Stateless Address Autoconfiguration
feature, or both.
- If your Ping to an IPv6 address was unsuccessful, verify the address
state of both interfaces. Both interfaces should have an address state of
Preferred. If either the target or source interface is not in the preferred
state, then either choose other interfaces for the test or change the interfaces
being used to the correct status and address state. To verify the
address state of the source interface, follow these steps:
- In System
i Navigator,
expand .
- In the right pane, right-click the IP address associated
with the interface, select Properties, and select the Options page.
This dialog allows you to view the preferred lifetime or valid lifetime for
the interface. Repeat these steps to check the state of the target interface
address.
