ipsec sa global-duration
Use ipsec sa global-duration to configure the global SA lifetime.

kilobytes.

Default command level

Parameters
seconds: Specifies the time-based global SA lifetime in seconds, in the range of 180 to 604800.
kilobytes: Specifies the traffic-based global SA lifetime in kilobytes, in the range of 2560 to
4294967295.
Usage guidelines
When negotiating to set up an SA, IKE prefers the lifetime of the IPsec policy or IPsec profile that it uses.
If the IPsec policy is not configured with its own lifetime, IKE uses the global SA lifetime.
When negotiating to set up an SA, IKE prefers the shorter one of the local lifetime and that proposed by
the remote.
You can configure both a time-based and a traffic-based global SA lifetime. An SA is aged out when it
has existed for the specified time period or has processed the specified volume of traffic.
The SA lifetime applies to only IKE negotiated SAs.
