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.
Display SFM Mastership Information from the Craft Interface
Purpose To determine the details of the SFM mastership from the craft interface.
Action To display SFM mastership information from the craft interface, use the following
command:
user@host> show chassis craft-interface
Sample Output
user@host> show chassis craft-interface
SFM LEDs:
SFM 0 1
---------------
Amber . .
Green * *
Blue * .
Meaning The command output shows that the SFM in slot 0 is online and functioning as the master.
The status colors represent the possible SFM operating states: Amber (Fail), Green (OK),
and Blue (Master). The (*) indicates the current operating state.
