Monitoring the CFEB Status
Steps To Take To monitor the CFEB status, follow these steps:
1.
Display the CFEB Environmental Status on page 422
2.
Display the CFEB Detailed Status on page 422
3.
Check CFEB LEDs on page 423

JUNOS Internet Software Network Operations Guide: Hardware
Step 1: Display the CFEB Environmental Status
Action To display the CFEB environmental status, use the following command-line interface (CLI) command: user@host> show chassis environment
Sample Output user@m5-host> show chassis environment
Class Item Status Measurement
Power Power Supply 0 OK
Power Supply 1 Absent
Temp Intake OK 22 degrees C / 71 degrees F
FPC 0 OK 23 degrees C / 73 degrees F
Power Supplies OK 23 degrees C / 73 degrees F
CFEB Intake OK 24 degrees C / 75 degrees F
CFEB Exhaust OK 30 degrees C / 86 degrees F
[...Output truncated...]
What It Means The command output displays the temperature and status of the CFEB intake and exhaust, which can be OK , Failed , or Absent .
Step 2: Display the CFEB Detailed Status
Action To display more detailed CFEB status, use the following CLI command: user@host> show chassis cfeb
Sample Output user@host> show chassis cfeb
CFEB status:
Slot 0 information:
State Master
Intake temperature 29 degrees C / 84 degrees F
Exhaust temperature 38 degrees C / 100 degrees F
CPU utilization 3 percent
Interrupt utilization 0 percent
Heap utilization 10 percent
Buffer utilization 22 percent
Total CPU DRAM 128 MB
Internet Processor II Version 1, Foundry IBM, Part number 164
Start time: 2004-09-28 03:07:54 PDT
Uptime: 9 days, 18 hours, 36 minutes, 15 seconds
Slot 1 information:
State Backup
What It Means The command output displays the temperature of the air passing by the CFEB intake and exhaust, in degrees Centigrade. It displays the total percentage of CPU, interrupt, heap space, and buffer space being used by the CFEB processor, including the total DRAM available to the CFEB processor. The command output displays the time when the CFEB started running and how long the CFEB has been running. A short uptime can indicate that there is a CFEB problem.
