seconds: Specifies the IKE SA lifetime in seconds, in the range of 60 to 604800.

Usage guidelines

Before an IKE SA expires, IKE negotiates a new SA. The new SA takes effect immediately after it is negotiated. The old IKE SA will be cleared when it expires.

If the communicating peers are configured with different IKE SA lifetime settings, the smaller setting takes effect.


# Set the IKE SA lifetime to 600 seconds for IKE proposal 1.
