Use undo sa duration to restore the default.
Syntax
sa duration { time-based seconds | traffic-based kilobytes }
undo sa duration { time-based | traffic-based }
Default
The SA lifetime of an IPsec policy or an IPsec profile equals the current global SA lifetime.
The time-based global SA lifetime is 3600 seconds, and traffic-based SA lifetime is 1843200 kilobytes.
Views
IPsec policy view, IPsec policy template view, IPsec profile view
Default command level
2: System level
Parameters
seconds: Time-based SA lifetime in seconds, in the range 180 to 604800.
kilobytes: Traffic-based SA lifetime in kilobytes, in the range 2560 to 4294967295.
Usage guidelines
When negotiating to set up an SA, IKE prefers the lifetime settings of the IPsec policy or IPsec profile that
it uses. If the IPsec policy or IPsec transform set is not configured with its own lifetime settings, IKE uses the
global SA lifetime settings, which are configured with the ipsec sa global-duration command.
When negotiating to set up an SA, IKE prefers the shorter ones of the local lifetime settings and those
proposed by the remote.
The SA lifetime applies to only IKE negotiated SAs. It is not effective for manually configured SAs.
