How to Read Optical Module Information on Brocade Fibre Channel Switches

Time: 2025-05-21
        When an optical module works on a switch, it is usually necessary to read the internal information of the module to understand its working status, such as module connection status, real-time transmit/receive optical power, temperature, etc., by identifying the module information, the encoding compatibility between the module and the switch can be checked; o how to check the working status and internal information of the optical module during use?
        Taking the Brocade 57-1000485-01 32G SW SFP+ module connected to a BROCADE G720 switch as an example, the following steps demonstrate the specific operations to read the information of the connected optical module on a BROCADE Fibre Channel switch.

1. Status of optical module
        Execute the command “diagshow ” to view the interface information;
        The output content of this command includes interface rate, duplex mode, interface status, etc. (Active as UP is a prerequisite for the work of optical module).
2. Optical module identification
        Execute the command “sfpshow port_number ” to view the identification information and digital diagnosis of the optical module on the interface.
        Explanation: port_number is the slot number and interface number where the module is located, you can execute the command “diagshow” to view or determine the interface number according to the switch panel; if you do not know the interface slot number and interface number, you can do not input it, and then it will output the brief identification information of all interfaces.
        The output under this command has two parts of information, one is module identification information, including module package, rate, model, vendor, serial number, wavelength, etc. 
        The other part is real-time data diagnostics, through which you can monitor whether the working status of the optical modules on both end devices is normal.
3. Interface rate configuration
        Execute the command “switchcfgspeed speed ” to adjust the interface rate, this command will change the speed of all interfaces of the switch.
        Note: speed refers to the desired interface speed to be configured, such as 16, 32, etc.
