3. Troubleshooting Functional Failures During Operation

3.10 IPv6 network communication failures

3.10.1 Communication is not possible or is disconnected

There are three probable causes of problems that occur during communication on an IPv6 network

employing a Switch:

1. A configuration related to IPv6 communication is changed.

2. The network configuration is changed.

3. A network device fails.

For causes 1 and 2, check the differences in the configuration and network configuration before

and after the change to uncover any cause that could disable communication.

This subsection describes the procedure for isolating the fault location to determine the cause of a

problem, and applies mainly to cause 3 failures. For example, IPv6 communication might not be

possible even when the configuration and the network configuration are correct, or for operation

that hitherto has been normal, IPv6 communication is no longer possible.

Use the following flowchart to isolate the fault location to identify the cause of the problem.

(1) Checking the log

One probable cause of disabled communication is a line failure (or damage). To display the

messages that indicate a hardware failure, carry out the procedure below. You can find these

messages in the log displayed by the Switch.
