Step 1.9

Return to the original session opened to your device.

Return to the original session logged in as lab and issue the show system users command to view information about users logged in to your team’s device.

Question: What is the source IP address of the

Telnet session established by the user walter?

Answer: The answer will vary. In the following example taken from srxA-1, the source IP address of the telnet session established by the user walter is 10.210.14.129.

Step 1.10

Issue the request system logout user walter command to force a log out for the user walter. Next, issue the show system users command to verify that the user session for walter was terminated.

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.

Question: At what temperature is a red alarm generated for the RE?

Answer: Assuming the fans are operational, the system raises a red alarm when the RE reaches 75 degrees Celsius. These threshold values can vary between different Junos devices.

Step 1.13

View details about your system’s hardware components using the show chassis hardware command.
