SHA2-512
The lifetime for phase 2 of the IKE negotiation, in seconds.
Constraints: A value between 900 and 3,600. The value must be less than the value for
Phase1LifetimeSeconds.
Default: 3600
The pre-shared key (PSK) to establish initial authentication between the virtual private gateway and the customer gateway.
Constraints: Allowed characters are alphanumeric characters, periods (.), and underscores (_). Must be between 8 and 64 characters in length and cannot start with zero (0).

during which the rekey time is randomly selected.
Constraints: A value between 0 and 100.
Default: 100
The margin time, in seconds, before the phase 2 lifetime expires, during which the
Amazon Web Services side of the VPN connection performs an IKE rekey. The exact time
of the rekey is randomly selected based on the value for
RekeyFuzzPercentage.

default, your customer gateway device must initiate the IKE negotiation and bring up the
tunnel. Specify start for Amazon Web Services to initiate the IKE
negotiation.
Valid Values: add | start
Default: add
