Fiber optic router status display
View the system status LED to determine the overall operating and power status of the router. For network engineers, knowing how to view and interpret SFP information from the Cisco command-line interface (CLI) is essential. Display diagnostics data and alarms for Gigabit Ethernet optical transceivers (SFP, SFP+, XFP, QSFP+, or CFP) installed in EX Series Switches or QFX Series Switches. When optical modules operate on a switch, it is usually necessary to read the module's internal information to understand its working status—such as connection status and real-time metrics like optical power and temperature. TL;DR Is your fiber connection unstable or slower than expected? You can check the physical line quality of your SFP module directly in RouterOS.
