An IKE negotiation failed because the server encountered a protocol that is not valid in the current Security Association (SA) negotiation phase. Phase 1 negotiation supports only the IKE protocol and phase 2 supports only the ESP and AH protocols.
Additional diagnostic messages that have the same message instance number will be issued to identify the impacted SA. The message instance number precedes the message number in the log output and is used to group related messages from the IKE daemon.
protocol_id is the numerical value that identifies the unsupported protocol.
phase is the phase (1 or 2) that the negotiation was in when the error occurred.
The SA negotiation failed; IKE daemon processing continues.
Contact the system programmer.
Notify the administrator of the remote security endpoint about this error and ask the administrator to verify that they are using only the supported protocols for SA negotiations that are listed in Explanation above.
