582 ! Monitoring Redundant SFM Status
Step 1: Display the SFM Summary Status
Action To display the SFM summary status, use the following CLI command:
user@host> show chassis sfm
Sample Output For M40e routers:
user@host> show chassis sfm
Temp CPU Utilization (%) Memory Utilization (%)
Slot State (C) Total Interrupt DRAM (MB) Heap Buffer
0 Online 37 3 0 64 16 46
1 Online - Standby 41 3 0 64 16 46
For M160 routers:
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
What it Means The command output displays the SFM slot number and the operating status of
each SFM as
Online, Offline, Present, or Empty.
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.
Alternative Action If the SFM summary command output indicates that there is a problem, you can
display more detailed SFM status information with the following CLI command:
user@host> show chassis sfm detail
For M40e routers:
user@host> show chassis sfm detail
Slot 0 information:
State Online
SPP Temperature 37 degrees C / 98 degrees F
SPR Temperature 41 degrees C / 105 degrees F
Total CPU DRAM 64 MB
Total SSRAM 8 MB
Internet Processor II Version 1, Foundry IBM, Part number 9
