ERROR_IPSEC_IKE_UNEXPECTED_MESSAGE_ID - 13888 (0x3640)

Technical Meaning

The error code ERROR_IPSEC_IKE_UNEXPECTED_MESSAGE_ID (13888, 0x3640) indicates that an unexpected message ID was received during the processing of IPsec/IKE protocol messages. This error is specific to the IPsec/IKE subsystem and pertains to the validation and handling of IKE messages.

Error Details

The IPsec/IKE protocol operates on a defined set of message IDs, each corresponding to a specific type of message such as notifications, exchanges, or responses. When an unexpected message ID is encountered, it suggests that the received message does not conform to the expected sequence or structure of IKE messages.

Usage Context

This error typically occurs during the establishment and maintenance of IPsec security associations (SAs) using the Internet Key Exchange (IKE) protocol. It can be triggered by various conditions, such as incorrect message sequencing, corrupted data, or misconfiguration in the IPsec/IKE implementation.

Developer Interpretation

Developers should interpret this error as an indication that there is a discrepancy between the expected and received IKE messages. This could be due to issues with the protocol stack, network transmission errors, or configuration mismatches. The presence of this error may necessitate further investigation into the IPsec/IKE setup and message handling logic.

Related Errors

• ERROR_IPSEC_IKE_PROCESSING (13896, 0x3650): Indicates a general processing failure in the IPsec/IKE protocol.
• ERROR_IPSEC_IKE_INVALID_MESSAGE_FORMAT (13872, 0x3640): Suggests that the format of an IKE message is invalid.
