Sometimes when troubleshooting SFP/QSFP problems, a good approach is to access the FPC PFE/VTY to check the alarms, info, etc... In most of the MPC cards, you can achieve this by accessing the vty and running "show qsfp <> info" or " show qsfp <> alarms". But in the LC9600 there is no QSFP option.

No QSFP options is available:

labroot@router> start shell pfe network fpc0

root@router-fpc0:pfe> show ?

In my lab the LC9600 card is in slot 3, PIC 0, and the QSFP in slot 0. (et-3/0/0)

FPC 3      REV 38  750-114437  BCEH7890     JNP10K-LC9600

 CPU      REV 05  750-116519  BCEJ3902     JNP10K-LC9600 PMB

 PIC 0          BUILTIN   BUILTIN      MRATE-4xQDD

  Xcvr 0    REV 01  740-058732  1DJQA22100H    QSFP-100GBASE-LR4

• Access FPC PFE with "> shell pfe network fpc3"
• The equivalent command to the show qsfp, goes like this:

root@router-fpc3:pfe> show picd optics cmd ?

Possible completions:

 alarm        Alarm information of the Xcvr

 diagnostics     Diagnostics information of the Xcvr

 dump_devdb_info   Xcvr devdb dump

 dump_xi_info     Xcvr Interface dump

 enh_diagnostics   Enhanced Diagnostics information of the Xcvr

 error        Xcvr Error counters

 fec_status      FEC status

 identifier      Identifier information of the Xcvr

 info         Information of the Xcvr

 list         Available xcvr in the PIC

• After you choose the correct option based on your needs, you have to specify the FPC, PIC, and port.

root@router-fpc3:pfe> show picd optics cmd alarm fpc_slot 3 pic_slot 0 port 3
