periodic
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 periodical 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.
