Adding Layer 4 Policies

Layer 4 policies encrypt only the payload of the packet. The source and destination addresses, protocol, and port in the IP header are sent in the clear. With Layer 4 policies, the Layer 4 header information is sent in the clear for traffic engineering and Service Level Agreement management (for example, Quality of Service controls or NetFlow statistics monitoring). You can create Layer 4 policies for point-to-point, hub and spoke, mesh, and multicast network topologies.
