Refer to the exhibit.

In Cisco ASA configurations using IKEv2, the integrity command defines the hash algorithm. To use SHA-512, the correct syntax is:

integrity sha512

Without this, the IKEv2 proposal is considered incomplete or mismatched with the peer. The encryption command sets encryption (AES-256, etc.), not hashing. The correct structure is:

crypto ikev2 policy <#>

encryption aes-256

integrity sha512

group 2

prf sha512
