Usage guidelines
With IPsec redundancy enabled, the system synchronizes the following information from the active
device to the standby device at configurable intervals:
•
Lower bound values of the IPsec anti-replay window for inbound packets.
•
IPsec anti-replay sequence numbers for outbound packets.
The synchronization ensures uninterrupted IPsec traffic forwarding and anti-replay protection when
the active device fails.
To configure synchronization intervals, use the
redundancy replay-interval
command.
Examples
# Enable IPsec redundancy.
<Sysname> system-view
[Sysname] ipsec redundancy enable

ipsec sa global-duration
Use ipsec sa global-duration to configure the global IPsec SA lifetime.
Use undo ipsec sa global-duration to restore the default.
Syntax
ipsec sa global-duration { time-based seconds | traffic-based kilobytes }
undo ipsec sa global-duration { time-based | traffic-based }
Default
The time-based global IPsec SA lifetime is 3600 seconds, and the traffic-based global lifetime is
1843200 kilobytes.

Parameters
time-based seconds
: Specifies the time-based global lifetime for IPsec SAs, in the range of 180
to 604800 seconds.
traffic-based kilobytes
: Specifies the traffic-based global lifetime for IPsec SAs, in the
range of 2560 to 4294967295 kilobytes. When traffic on an SA reaches this value, the SA expires.
Usage guidelines
You can also configure IPsec SA lifetimes in IPsec policy view or IPsec policy template view. The
device prefers the IPsec SA lifetimes configured in IPsec policy view or IPsec policy template view
over the global IPsec SA lifetimes.
