About Network Troubleshooting and Observability
The following tables describe the major features of the Oracle Solaris network protocol stack, grouped by layer. Information about the tools that you use to observe and monitor network traffic usage and display the configuration for each of these features is also provided. For the tools that you use to manage and observe various networking features, such as the dladm and dlstat commands, the subcommands that are specific to each feature are also provided.
