Description (partial)

Traffic may get dropped on ingress due to 'AppNavNoTunnel' when there are no other indications of forwarding issues with the AppNav tunnel for other traffic that is being optimized to the same Service Nodes.

Running Packet Trace for the traffic will indicate a drop code of 'AppNavNoTunnel' in the FIA and this connection will fail.
