Check the switch s optical port bandwidth

Fibre interconnection and data room reference Published 10 May 2026

Use this reference to prepare product questions for FD SOLUCIONES. Check interfaces, capacity, protection and installation requirements against the current product documentation.

You can check a switch's optical port bandwidth using CLI commands like show interface or via the web-based Optical Module Status page, which displays port speed, transceiver type, and real-time traffic statistics.

Using CLI Commands

Connect to the switch via SSH or console. Check port status and bandwidth: Run show interface to display the port negotiation speed, link status, and traffic statistics. For example, a 25Gb/s SFP port may show BW 25000000 Kbit/sec indicating 25 Gbps bandwidth.

Use show interface status to list all ports and their speeds. View transceiver details:show interfaces transceiver detail provides DOM/DDM values such as Tx/Rx power, temperature, voltage, and bias current.show inventory lists installed SFP modules with part numbers, serial numbers, and type information. Monitor bandwidth utilization:show interface summary or show interface shows real-time RX/TX bits per second and packet counts, useful for troubleshooting or performance monitoring.

Using Web-

Based Utility

Log in to the switch's web interface. Navigate to Status and Statistics > Diagnostics > Optical Module Status. Select the switch and port to view: Port number and descriptionTransceiver type and serial numberOperating temperature and voltageInput/Output optical powerLink status and fault indicators Key ConsiderationsEnsure the SFP module is compatible with the switch to avoid errors or unsupported transceiver messages.

Optical port bandwidth is determined by the SFP module type (e.g., 1G, 10G, 25G, 40G, 100G) and the switch port configuration.

Monitoring DO

M values helps verify that the optical link is operating within safe parameters and can prevent link degradation or failures. By combining CLI commands and web-based diagnostics, you can accurately check the bandwidth, monitor traffic, and ensure the optical port is functioning correctly.
