movement along the path in both directions: from the location of the camera (temporarily, the
computer) to the FortiRecorder, and the FortiRecorder to the camera.
If the routing test succeeds, continue with step 4.
If ping shows some packet loss, investigate:
• cabling to eliminate loose connections
• ECMP, split horizon, or network loops
• dynamic routing such as OSPF
• all equipment between the ICMP source and destination to minimize hops
If the routing test fails, and ping shows total packet loss:
• verify cabling to eliminate loose connections
• continue to the next step
In networks using features such as asymmetric routing, routing success in one direction does
not guarantee success in the other.
Connectivity via ICMP only proves that a route exists. It does not prove that connectivity also
exists via other protocols at other layers such as HTTP.
Both ping and traceroute require that network nodes respond to ICMP. If you have disabled
responses to ICMP on your network, hosts may appear to be unreachable to ping and
traceroute, even if connections using other protocols can succeed.
