Troubleshooting Network Processing Cards on the SRX3400 Services Gateway

To troubleshoot an NPC, follow these guidelines:

  • Make sure the NPC is properly seated in the midplane and its screws are tightened.
  • Issue the CLI show chassis fpc command with the slot number to check the status of installed NPCs. As shown in the sample output, the value Online in the column labeled State indicates that the NPC is functioning normally:

    user@host> show chassis fpc 5
                  Temp  CPU Utilization (%)   Memory    Utilization (%)
Slot State            (C)  Total  Interrupt      DRAM (MB) Heap     Buffer
  5  Online            42      6          0       1024       16         57

    For more detailed output, add the detail option. The following example does not specify a slot number, which is optional:


    user@host> show chassis fpc 5 detail

    Slot 5 information:
  State                                 Online
  Temperature                        42 degrees C / 107 degrees F
  Total CPU DRAM                   1024 MB
  Total RLDRAM                      256 MB
  Total DDR DRAM                   4096 MB
  Start time:                           2007-07-10 12:28:42 PDT
  Uptime:                               1 hour, 33 minutes, 43 seconds
