Parameters
interval: Specifies the number of seconds between IKE keepalives, in the range of 20 to 28800.
Usage guidelines
To detect the status of the peer, configure IKE DPD instead of the IKE keepalive feature, unless IKE DPD is not supported on the peer.
The keepalive timeout time configured at the local 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 interval to 200 seconds
<Sysname> system-view [Sysname] ike keepalive interval 200
