### Local Class Properties

Name | Data Type | Default Value | Qualifiers

Name | Data Type | Value
AuthenticationMethod | uint16 |
Description | string | AuthenticationMethod is an enumeration that specifies the proposed authentication. The list of methods was generated from Appendix A of RFC2409. Note that the enumeration is different than the RFC list and aligns with the values in IKESAEndpoint.AuthenticationMethod. There is one change to the list - the value 65000 has special meaning. It is a special value that indicates that this particular proposal should be repeated once for each authentication method corresponding to credentials installed on the machine. For example, if the system has a pre-shared key and an public-key certificate, a proposal list would be constructed which includes a proposal that specifies a pre-shared key and a proposal for any of the public-key certificates.

Values | string | Other, Pre-shared Key, DSS Signatures, RSA Signatures, Encryption with RSA, Revised Encryption with RSA, DMTF/IANA Reserved, Any, Vendor Reserved
CipherAlgorithm | uint16 |
Description | string | CipherAlgorithm is an enumeration that specifies the proposed encryption algorithm. The list of algorithms was generated from Appendix A of RFC2409. Note that the enumeration is different than the RFC list and aligns with the values in IKESAEndpoint.CipherAlgorithm.

GroupId | uint16 |
Description | string | The property GroupId specifies the proposed phase 1 security association key exchange group. This property is ignored for all aggressive mode exchanges (IKEAction.ExchangeMode = 4). If the GroupID number is from the vendor-specific range (32768-65535), the property VendorID qualifies the group number. Well-known group identifiers from RFC2412, Appendix E, are: Group 1='768 bit prime', Group 2='1024 bit prime', Group 3 ='Elliptic Curve Group with 155 bit field element', Group 4= 'Large Elliptic Curve Group with 185 bit field element', and Group 5='1536 bit prime'.

HashAlgorithm | uint16 |
Description | string | HashAlgorithm is an enumeration that specifies the proposed hash function. The list of algorithms was generated from Appendix A of RFC2409. Note that the enumeration is different than the RFC list and aligns with the values in IKESAEndpoint.HashAlgorithm.

MaxLifetimeKilobytes | uint64 |
Description | string | MaxLifetimeKilobytes specifies the maximum kilobyte lifetime the IKE message sender proposes for an SA to be considered valid after it has been created. A value of zero (the default) indicates that there should be no maximum kilobyte lifetime. A non-zero value specifies the desired kilobyte lifetime.

MaxLifetimeSeconds | uint64 |
Description | string | MaxLifetimeSeconds specifies the maximum time the IKE message sender proposes for an SA to be considered valid after it has been created. A value of zero indicates that the default of 8 hours be used. A non-zero value indicates the maximum seconds lifetime.

VendorID | string |
Description | string | VendorID identifies the vendor when the value of GroupID is in the vendor-specific range, 32768 to 65535.
ModelCorrespondence | string | CIM_IKESAEndpoint.VendorID, CIM_IKEProposal.GroupId
