Default
An IKEv2 proposal named default exists, which has the lowest priority and uses the following
settings:
In non-FIPS mode:
Encryption algorithm—AES-CBC-128 and 3DES.
Integrity protection algorithm—HMAC-SHA1 and HMAC-MD5.
PRF algorithm—HMAC-SHA1 and HMAC-MD5.
DH group—Group 5 and group 2.
In FIPS mode:
Encryption algorithm—AES-CBC-128 and AES-CTR-128.
Integrity protection algorithm—HMAC-SHA1 and HMAC-SHA256.
PRF algorithm—HMAC-SHA1 and HMAC-SHA256.
DH group—Group 14 and group 19.

Parameters
proposal-name: Specifies a name for the IKEv2 proposal. The proposal name is a case-insensitive
string of 1 to 63 characters and cannot be default.
Usage guidelines
An IKEv2 proposal contains security parameters used in IKE_SA_INIT exchanges, including the
encryption algorithms, integrity protection algorithms, PRF algorithms, and DH groups.
An IKEv2 proposal must have a minimum of one set of security parameters, including one encryption
algorithm, one integrity protection algorithm, one PRF algorithm, and one DH group.
In an IKEv2 proposal, you can specify multiple parameters of the same type. The parameters of
different types combine and form multiple sets of security parameters. If you want to use only one set
of security parameters, configure only one set of security parameters for the IKEv2 proposal.
Examples
# Create an IKEv2 proposal named prop1. Specify the encryption algorithm AES-CBC-128, integrity
protection algorithm SHA1, PRF algorithm SHA1, and DH group 2.
