Parameters

interval interval: Specifies a DPD triggering interval in the range of 10 to 3600 seconds.

retry seconds: Specifies the DPD retry interval in the range of 2 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 IKEv2 peers. For an earlier detection of dead peers, use the periodic triggering mode, which consumes more bandwidth and CPU.

The triggering interval must be longer than the retry interval, so that the device will not trigger a new round of DPD during a DPD retry.

Examples

# Configure on-demand IKEv2 DPD. Set the DPD triggering interval to 10 seconds and the retry interval to 5 seconds.
