Parameters
Seconds: Specifies the IKE SA lifetime in seconds, in the range of 60 to 604800.
Usage guidelines
If the communicating peers are configured with different IKE SA lifetime settings, the smaller one takes
effect.
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.
Examples
# Set the IKE SA lifetime to 600 seconds for IKE proposal 1.
