EZD1760I
Proposal proposal_number contains an unsupported transform ID transform_id for transform type transform_type

Explanation

The Security Association (SA) proposal is not accepted because it contains a transform with an unsupported ID. Internet Key Exchange (IKE) daemon processing continues to the next proposal. If no proposals are accepted, the SA negotiation fails. Failure is indicated by message EZD0985I, EZD1021I, or EZD1022I being issued later in syslog.

In the message text:
proposal_number
The number of the proposal that contains the transform with the unsupported ID.
transform_id

transform_type
The transform type of the transform with the unsupported ID. The transform types are listed in RFC 5996 Internet Key Exchange (IKEv2) Protocol. See Related protocol specifications for information about accessing RFCs.

System action

If the IKE daemon does not accept any of the proposals, the negotiation fails; IKE daemon processing continues.

Operator response

None.

System programmer response
