Parameters

seconds: Specifies the number of seconds between IKE keepalives. The value range for this argument is 20 to 28800.

Usage guidelines

If the local end receives no keepalive packets from the peer during the timeout time, the IKE SA is deleted along with the IPsec SAs it negotiated.

The keepalive timeout time configured at the local end must be longer than the keepalive interval configured at the peer. Because more than three consecutive packets are rarely lost on a network, you can set the keepalive timeout time to three times as long as the keepalive interval.

Examples

# Set the keepalive timeout time to 20 seconds.

<Sysname> system-view
[Sysname] ike keepalive timeout 20
