Common VPN Connection Manager error messages

The VPN Connection Manager logs two messages in the QTOVMAN job log when an error occurs with a VPN connection.

The first message provides details regarding the error. You can view information about these errors in System i® Navigator by right-clicking the connection in error and selecting Error Information.

The second message describes the action you were attempting to perform on the connection when the error occurred. For example, starting or stopping it. Messages TCP8601, TCP8602, and TCP860A, described below, are typical examples of these second messages.
