The output fields for theshow chassis routing-engine command include:
* Temperature: Temperature of the air flowing past the Routing Engine.
The correct answer is A. show chassis environment.
The show chassis environment command displays the environmental status and component temperature readings of the Juniper device, including the Routing Engine's CPU temperature. It provides a comprehensive view of the temperature, voltage, fan speed, and power supply status of the device.
Here is an example output of the show chassis environment command:
cssuser@router> show chassis environment Class Item Status Measurement Power FPC 0 Power Supply 0 OK Input: 100-240V AC Power FPC 0 Power Supply 1 OK Input: 100-240V AC Fans Top Rear Fan OK Spinning at normal speed Bottom Rear Fan OK Spinning at normal speed Top Middle Fan OK Spinning at normal speed Bottom Middle Fan OK Spinning at normal speed Top Front Fan OK Spinning at normal speed Bottom Front Fan OK Spinning at normal speed Temp Routing Engine OK 37 degrees C / 98 degrees F FPC 0 OK 33 degrees C / 91 degrees F The output shows the current status of the device's power supplies, fans, and temperatures, including the temperature of the Routing Engine's CPU, which is listed under the "Temp" section. In this example, the Routing Engine's CPU temperature is 37 degrees Celsius or 98 degrees Fahrenheit.
The show chassis routing-engine command displays the status of the Routing Engine, including the CPU utilization, memory usage, and process status. It does not provide temperature readings.
The show chassis temperatures command displays only the temperature readings of the device's components, including the Routing Engine. However, it does not provide additional environmental status information, such as power supply and fan status.
The show chassis status command displays the overall hardware status of the device, including the status of power supplies, fans, and other hardware components. However, it does not provide detailed temperature information.
