What does the command 'diagnose system print netstat' display?

The command 'diagnose system print netstat' is specifically designed to display network statistics associated with active Internet connections on a Fortinet device. When this command is executed, it provides an overview of all the current TCP/IP connections, including the local and remote IP addresses, port numbers, protocol type, connection states, and more. This information is crucial for network administrators to monitor active sessions, troubleshoot connectivity issues, and analyze network performance.

The significance of this information lies in its ability to enable real-time visibility into the status of network connectivity, which can be instrumental in diagnosing issues or ensuring that the network is functioning optimally. Knowing the details of active connections helps in identifying potential security threats, unauthorized access, or misconfigurations that may need attention.

In contrast, the other options do not align with what the command accomplishes. For example, the command does not provide information about system memory usage, routing table entries, or DOS attack thresholds, which are associated with different commands or processes within the Fortinet ecosystem. Each of these alternate data points is vital in its own right but does not pertain to the specific purpose of the 'diagnose system print netstat' command.
