Constraints: A value between 0 and 100.

Default: 100

Type: Integer

Required: No

RekeyMarginTimeSeconds

The margin time, in seconds, before the phase 2 lifetime expires, during which the AWS side of the VPN connection performs an IKE rekey. The exact time of the rekey is randomly selected based on the value for RekeyFuzzPercentage.
