6. Na-eji SRX300 arụ ọrụ
The SRX300 Services Gateway operates on Juniper's Junos OS. Configuration and management are primarily performed via the command-line interface (CLI) through the console port or SSH, or via the J-Web graphical user interface (GUI).
- Accessing the CLI: Use a terminal emulator connected to the console port or an SSH client to connect to the device's IP address.
- J-Web GUI: If enabled, access the J-Web interface by entering the device's IP address into a web ihe nchọgharị.
- Ọnọdụ nlekota: Regularly check the front panel LEDs (PWR, ALARM, STAT, HA) for operational status. Consult the Junos OS documentation for detailed LED behavior.
- Basic Commands (CLI examples):
show interfaces terse: Displays a summary of network interface status.show system alarm: Shows current system alarms.show security flow session: Displays active network sessions.
For detailed configuration and advanced features, refer to the official Juniper Networks Junos OS documentation.
