This parameter is supported if you create an vpn attachment in single-tunnel mode. Whether to enable the DPD (peer survival detection) function.
true (default): enables DPD. The initiator of the IPsec-VPN connection sends DPD packets to check the existence and availability of the peer. If no feedback is received from the peer within the specified period of time, the connection fails. In this case, ISAKMP SA and IPsec SA are deleted along with the security tunnel.
false: disables DPD. The initiator of the IPsec-VPN connection does not send DPD packets.
