EZD1029I
Certificate usage value ( usage_value ) not supported

Explanation

An IKE negotiation failed because the certificate usage value is not supported. The values currently supported are the integer representation of the digital signature flag or any. This error occurred when verifying the signature of the remote IKE daemon certificate.

Additional diagnostic messages that have the same message instance number will be issued to identify the impacted Security Association (SA). The message instance number precedes the message number in the log output and is used to group related messages from the IKE daemon.

usage_value is the number that represents the certificate usage value.

System action

The certificate could not be verified and the message was not processed; IKE daemon processing continues.

Operator response

Ensure that the certificates of the responder of the IKE exchange are configured correctly. This error might be due to the remote security endpoint sending an unsupported certificate; ensure the remote security endpoint is using valid certificates.

System programmer response

None.

Module

asn_utils.cpp

Procedure name

None.
