•Operation Level: For IPSec backup. One level is Main and the other is Backup. If the Main instance is
down then switch to the backup instance.
•Authentication method: PSK Client, PSK Server, RSA X.509 Client and RSA X.509 Server. Client is the
device which starts the IPSEC connection.
•Remote VPN endpoint: Domain name or IP address of the remote endpoint. It can be visited from

•DPD action: Controls the use of the Dead Peer Detection protocol (DPD, RFC 3706) where
R_U_THERE notification messages (IKEv1) or empty INFORMATIONAL messages (IKEv2) are
periodically sent in order to check the activeness of the IPsec peer. The values are clear, hold, and
restart, all of which activate the DPD and determine the action to perform on a timeout. Clear: The
connection is closed with no further actions taken. Hold: Installs a trap policy, which will catch
matching traffic and tries to re-negotiate the connection on demand. Restart: Immediately
triggers an attempt to re-negotiate the connection. The default is none which disables the active
sending of DPD messages
•DPD delay: Defines the period time interval with which R_U_THERE messages/INFORMATIONAL
exchanges are sent to the peer.
•DPD timeout: Defines the timeout interval, after which all connections to a peer are deleted in case
of inactivity.
