Diagnostic Flowcharts
Below is a summary of the types of network tests in the diagnostic flowcharts. To diagnose
your problem, first check the connections and configuration on your system (Flowcharts 1
through 5). If this does not solve your problem, use flowcharts 6 through 8 to test and/or verify
connectivity with a remote system.
1 Transport Level Test using Internet Services
2 Network Connectivity Test
3 Name Services Test
4 Interface Test
5 Interface Test (continued)
6 Router Remote Loopback Test
Transport Level Loopback Test using Internet Service: Checks round-trip communication
between Transport Layers on the source and target host using telnet.
Network Connectivity Test: Checks round-trip communication between Network Layers on
the source and target host using the ping(1M) diagnostic.
Name Services Test: Checks host name and IPv6 address resolution.
Interface Test: Verifies the configuration of the network interface on a host using the lanscan,
and ifconfig commands.
Router Remote Loopback Test: Verifies the connection between local and remote nodes
through IPv6 routers using the ping and netstat commands.
