Meaning Use the show chassis fpc command to identify whether there is a problem with any of
the FPCs installed in the router. The command output displays a brief status of all the
FPCs installed in the router. The state can be online, dead, diag, dormant, empty, online,
probed, or probe-wait. If the FPC state is dead, an alarm occurs. For more detailed
information about the FPC states, see the Junos OS Routing Protocols Configuration Guide,
Class of Service Configuration Guide, and Junos OS System Basics and Services Command
Reference.
The temperature is that of the air flowing past the FPC. If the temperature is too high, an
alarm occurs.
The CPU and memory information is the total percentage of CPU being used by the FPC
processor, the total CPU being used by the FPC processor, the percentage of CPU being
used for interrupts, and the total DRAM available to the FPC processor. The percentage
of heap space (dynamic memory) reflects the buffer space being used by the FPC
processor. If the heap space exceeds 80 percent, there might be a software problem
(memory leak).
The output also displays the percentage of buffer space being used by the FPC processor
for buffering internal messages.
Check FPC Status and Uptime
Purpose To verify FPC error conditions by checking the FPC status and uptime for a particular FPC
slot.
Action To display the status and uptime for a particular FPC slot, use the following command:
user@host> show chassis fpc detail fpc-slot
Sample Output
user@M160> show chassis fpc detail 3
Slot 3 information:
State Online
Temperature 36 degrees C / 96 degrees F
Total CPU DRAM 32 Mbytes
Total SRAM 4 Mbytes
Total SDRAM 256 Mbytes
