    Display SFM Mastership at the Command Line

    Purpose

    To determine the SFM mastership at the command line.

    Action

    To display the SFM summary status at the command line, 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
    

    Meaning

    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 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.
