How to view port status and Optical Module information on Juniper Switches

      Optical modules work on the switch usually need to read the internal information of the module to understand its working status, such as module connectivity and real-time collection of light, temperature, etc., through the identification of the module information can be detected by the module and the switch's coding compatibility; then how to view the working status of the optical module in the process of use as well as the internal information?
      The following is an example of accessing Juniper EX4550 switch with Moduletek limited SFP-10G-LR optical module to show you the specific operation of reading the information of the accessed optical module on Juniper switch.

Figure 1 Schematic diagram of optical module accessing the switch

1. Status of Optical Module
      Execute the command "show interface interface-type interface-number " to view the interface information;
The information output under this command contains the interface rate, module link status (Physical link for Up is a prerequisite for the work of the optical module), and some statistical information, which can be used for troubleshooting.
      Description：interface-type interface-number is the type and number of the interface where the module is located, you can execute the command "show interface" to check the interface type and then determine the interface number according to the switch panel; if you don't know the interface type and number, you can not enter it. If you do not know the interface type and interface number, you can not input them, and the information of all interfaces will be output at this time.

2、Switch identifies the module
      Execute the command "show chassis hardware " to view the hardware information of the device, the type and serial number of each interface module under the PIC slot;

Figure 3 Optical module identification information

      Execute the command "show chassis pic fpc-slot number pic-slot number " to view the specific board/slot and optical module information, including PIC slot type and status, optical module type, vendor name, vendor model number, wavelength and so on.
Explanation: number is the slot number, which can be obtained in the output of the above View Hardware Information command.

3. Optical Module DDM Data
      Execute the command "show interfaces diagnostics optics" to view the DDM information of the optical module on the device interface;
      The information output under this command includes real-time data diagnostics and threshold ranges. By focusing on the received optical power, transmitted optical power, temperature value, current value, etc., we can check whether the working status of the optical modules on both ends of the equipment is normal.
