MONITOR AND CUSTOMIZE DASHBOARD VIEW ON A SWITCH

How to view optical switch parameters

If you know the model or type of an optical module, you can view the section "Pluggable Modules for Interfaces" in the Hardware Description to look up parameters of the optical module, including the center wavelength, transmission distance, fiber types supported, receive optical. 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. The Cisco Small Business Series Switches allow you to plug in a Small Form-factor Pluggable (SFP) transceiver in their optical modules to connect fiber optic cables. This guide provides complete, step-by-step CLI commands to view module type, DOM/DDM diagnostic data, vendor details, and compatibility information, fully compliant with Cisco IOS and IOS-XE command standards.

View port configuration of fiber optic switch

In the Privileged EXEC mode of the switch, use the show fiber-ports-optical-transceiver command by entering the following: interface interface-id — (Optional) Specify an Ethernet port ID. If you're looking to learn how to configure fiber optics on a Cisco switch, it's important to first configure the switch settings so it's ready for fiber optics. This guide uses the Moduletek SFP-25G-SR optical module connected to a Cisco C9300 switch as an example. You can obtain the list of compatible transceivers by visiting the Cisco Optics-to-Device Compatibility Matrix or run the show interface show interface transceiver supported-list command.

View switch ports via the core

To see the summary information on all ports on the switch, enter the show interface status command with no arguments. Use the mod_num argument to specify a particular module number and display detailed information on that. The core switch is managed, and I have logged in to look at the most used ports to try and take some of the guess work out of which are uplinks to other cabinets.

How to view fiber optic switch ports

In the Privileged EXEC mode of the switch, use the show fiber-ports-optical-transceiver command by entering the following: interface interface-id — (Optional) Specify an Ethernet port ID. If you run fiber or copper uplinks in a small office, home lab, or data closet, SFPs (and SFP+) are the little parts that keep your links alive. This guide gives a practical, CLI-focused workflow for checking SFP health and diagnostics on Cisco switches, shows the exact commands you'll use. Connect to the Cisco switch using a console cable or through a remote management interface.

Interconnection between switch ports and optical ports

When you connect two 1000BASE-T switches with SFP ports to achieve Gigabit Ethernet, there are two methods: through standard Ethernet cable plugged into the built-in Ethernet ports of each switch, or use the SFP ports with a copper SFP module. This article will discuss the two available interconnection options between 100BASE-T Ethernet switches that come with SFP ports. An all-optical Ethernet switch is a network switch whose service ports are entirely optical, meaning every interface uses fiber rather than copper.
