4.4.4 SFP Information
You can check the physical or operational status of an SFP module via the SFP Module Information page. This page shows the
operational status, such as the transceiver type, speed, and wavelength and supports distance of SFP module on a specific
interface. You can also use the hyperlink of port no. to check the statistics on a speficic interface. The SFP Module Information
