Monitor the SFM Status
To monitor the SFM status:
1.
Display the SFM Summary Status on page 444
2.
Display the SFM LED Status at the Command Line on page 445
3.
Check the SFM LED Status on the Faceplate on page 446
4.
Display the SFM Environmental Status on page 446
Display the SFM Summary Status
Purpose To isolate problems in the SFM by checking the SFM summary status.
Action To display the SFM summary status, use the following command:
user@host> show chassis sfm
Sample Output
user@host> show chassis sfm
Temp CPU Utilization (%) Memory Utilization (%)
Slot State (C) Total Interrupt DRAM (MB) Heap Buffer
0 Online 41 2 0 64 16 46
1 Offline --- Hard FPC error ---
2 Online 43 2 0 64 16 46
3 Online 44 2 0 128 7 46
Meaning The command output displays the SFM slot number: 0, 1, 2, or 3. The output also displays
the operating status of each SFM as Online, Offline, or Empty.
In the sample output, the root cause of the SFM1 failure may be an FPC problem.
The command output displays the temperature of air passing by the SFM, in degrees
Centigrade. It displays the SFM CPU usage, including the total percentage used by the
SFM processor and the percentage used for interrupts.
The command output also displays the percentage of memory usage, including the total
DRAM available to the SFM processor, in megabytes (MB), and the percentage of heap
space (dynamic memory) being used by the SFM processor. Heap utilization greater than
80 percent can indicate a software problem (memory leak). The output shows the
percentage of buffer space being used by the SFM processor for buffering internal
messages.
If the SFM summary command output indicates that there is a problem, you can display
more detailed SFM status information with the following command:
user@host> show chassis sfm detail
The command output displays the following information:
Sample output user@host> show chassis sfm detail
