The debug commands on the ASA have a slightly different syntax than IOS. The two debugs you will usually find yourself using are debug crypto ikev1 and debug crypto ipsec Settings keyexchange=ikev1 authby=secret ike=aes256-sha-modp1536 esp=aes128-sha-modp1024 rekey=no auto=start reauth=no  This is the asa crypto map I was using.

Diferencia entre IKEv1 e IKEv2 - Protocolos Y Formatos

Select post section. In the last article, we configured a site-to-site (or LAN-to-LAN) VPN tunnel between two Cisco IOS routers using IKEv2 and crypto maps. IKEv2 provides more security than IKEv1 because it uses separate keys for each side. IKEv1 does not offer support for as many algorithms as  IKEv2 requires Asymmetric Authentication.

Enable IKEv2 on Outside Interface. Compared with IKEv1, IKEv2 simplifies the SA negotiation process. IKEv2 uses two exchanges (a total of 4 messages) to create an IKE SA and a pair of IPSec SAs. To create multiple pairs of IPSec SAs, only one additional exchange is needed for each additional Cisco introduced support for IKEv2 beginning with ASA version 8.4 but in this article we will focus only on the legacy IKEv1 implementation. In this article we have provided an basic introduction of how to setup and IPsec site-to-site VPN between two ASA devices. Differences between IKEv1 and IKEv2.
