For more detailed information on the differences and an explanation of the packet exchange, refer to IKEv2 Packet Exchange and Protocol Level Debugging. VPN Clients are Unable to Connect with ASA/PIX Problem. Whereas in IKEv1 there was a clearly demarcated phase1 exchange that consisted of 6 packets followed by a phase 2 exchange that consisted of 3 packets, the IKEv2 exchange is variable. There are two tunneling modes available for MX-Z devices configured as a Spoke:. It MIGHT be initiated by either end of the IKE_SA after the initial exchanges are completed. If you see MM_ACTIVE (This means phase 1 has completed in Main Mode, and is active) So phase 1 has completed successfully, you need to jump forward and troubleshoot Phase 2.
