>>Along with the above outputs, the logs will have below messages if the QSFP's are inserted in wrong ports ,



Dec 4 12:27:55 JTAC : %PFE-2: fpc0 pic:0 port:0 100G QSFP Module not supported on this port.
Dec 4 12:27:55 JTAC : %PFE-2: fpc0 pic:0 port:1 100G QSFP Module detected but not configured. Configuration required for 100g interface creation.


 

Solution

The solution for the 1000gig interfaces to be seen of devices and to be up, we need to check below details,

 

  1. We need to insert the 100gig ports as show in below port panel documentation as 100gig ports will not work on all the ports


https://www.juniper.net/documentation/us/en/hardware/qfx10002/topics/topic-map/qfx10002-port-panel.html#port-panel-QFX10002-36Q__d15647e167

  1. Once we have inserted the optics in correct port , add the below configuration to make 100gig interfaces up .

We need to add correct port umber where we have 100gig QSPF inserted

        set chassis fpc [slot-number] pic [slot number] port [port-number] speed 100g

  1. Based on documentation the interfaces will not be visible unless we configure speed under chassis hierarchy

Note: When we enable 100gig port on the device, the two adjacent ports will be  disabled , please check ofr the port panel documentation shred above for the links that will be disabled and the ports that can be configured as 100gig
