Usage guidelines
This command takes effect when the device resides in the private network behind a NAT device. The device must send NAT keepalive packets regularly to its peer to keep the NAT session alive, so that the peer can access the device.
The NAT keepalive interval must be shorter than the NAT session lifetime.
Examples
# Create an IKEv2 profile named profile1.
<Sysname> system-view [Sysname] ikev2 profile profile1
# Set the NAT keepalive interval to 1200 seconds.
