2. Troubleshooting for Connection Failure
Incorrect settings are often the cause of issues where the connection was not established within the installation schedule when trying to establish the connection.
The following are typical examples.
Incorrect router settings for the IP address assignment (auto/fixed)
Incorrect password settings
Authentication method negotiation failure
MTU negotiation failure
For "1. Incorrect router settings for the IP address assignment (auto/fixed)," troubleshoot the problem using the CCO document as reference. For the other problems, it could be an issue that depends on the destination equipment or it is difficult to determine where and what to fix by looking at show running-config. Please obtain debug logs by enabling debugging. You can identify the cause of the connection failure by checking the results of debug logs.
The debug logs you are recommended to obtain in the first step are as follows:
debug ppp authentication
debug ppp negotiation
debug pppoe event
The CCO document introduces the detailed description of how to check the obtained debug logs. Please see the CCO document as well.
