Question: What is the temperature and status of the
Routing Engine (RE)?
Answer: Your details might vary. The sample capture shows a temperature of 37 degrees Celsius and a status of OK.
Question: Name another show chassis command that displays the RE temperature. (Hint: Use the ?.)
Answer: As the following capture shows, the show chassis routing-engine command displays the RE temperature as well as other RE-specific details.
