    Display the SFM Summary Status

    Purpose

    To obtain information about the SFM summary.

    Action

    To display the SFM summary status, use the following 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 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

    For M40e routers:

    user@host> show chassis sfm detail

    In addition to the command output displayed for the show chassis sfm command, the show chassis sfm detail command displays the temperature of air passing by the SPP and SPR cards (the two SFM serial components), in degrees Centigrade. It displays the total CPU DRAM and SRAM being used by the SFM processor. The command output displays the time that the SFM became active and how long the SFM has been up and running. A small uptime means that the SFM came online a short time ago and could indicate a possible SFM error condition.

    To display the status of a particular SFM, use the following command:

    user@host> show chassis sfm sfm-slot

    To display detailed status information about a particular SFM, use the following command:

    user@host> show chassis sfm detail sfm-slot
