Parameters
interval interval: Specifies a DPD triggering interval in the range of 1 to 300 seconds.
retry seconds: Specifies the DPD retry interval in the range of 1 to 60 seconds. The default is 5
seconds.
on-demand: Triggers DPD on demand. The device triggers DPD if it has IPsec traffic to send and
has not received any IPsec packets from the peer for the specified interval.
periodic: Triggers DPD at regular intervals. The device triggers DPD at the specified interval.
Usage guidelines
DPD is triggered periodically or on-demand. As a best practice, use the on-demand mode when the
device communicates with a large number of IKE peers. For an earlier detection of dead peers, use
the periodic triggering mode, which consumes more bandwidth and CPU.
When DPD settings are configured in both IKE profile view and system view, the DPD settings in IKE
profile view apply. If DPD is not configured in IKE profile view, the DPD settings in system view apply.
It is a good practice to set the triggering interval longer than the retry interval so that a DPD detection
does not occur during a DPD retry.
Examples
# Configure DPD to be triggered every 10 seconds and every 5 seconds between retries if the peer
does not respond.
