The IP Manager is able to discover and monitor IPSec tunnels and Internet Key Exchange (IKE) tunnels between IPSec-enabled routers on IPv4 networks. IPSec is a standardized framework for securing IP communications at the network layer, and IKE is a standardized key exchange protocol that is used to set up IPSec tunnels. Tunnel discovery is described in “Discovery and short discovery of IPSec tunnels” on page 168.
