Part 3: Upgrading the Junos OS
In this lab part, you will retrieve a Junos OS package from a remote server and upgrade your assigned device. Note that to keep the software consistent, you upgrade the device to the same version of the Junos OS that it is currently running.
Step 3.1
Enter configuration mode and load the lab4-part3-start.config file from the/var/home/lab/ijos/ directory. Commit your configuration and return to operational mode when complete.
lab@srxA-1> configure Entering configuration mode

Step 3.2
Use the file copy command in conjunction with FTP to retrieve the install image named junos-srxsme-12.1R1.9-domestic.tgz from the server. Refer to the management network diagram for the server’s IP address. Use the username ftp and a password of ftp. Save the image to the /var/tmp directory on the local device.

Introduction to the Junos Operating System
Question: Did the image successfully transfer from the server to the /var/tmp directory on your device?
Answer: The image should successfully transfer. If not, check with your instructor for assistance.
Note
If there is not enough room in the /var/tmp directory to accommodate the software package, notify your instructor.
Step 3.3
Verify that the software package transferred correctly to the local /var/tmp directory by using the file list /var/tmp | match junos command.
lab@srxA-1> file list /var/tmp/ | match junos junos-srxsme-12.1R1.9-domestic.tgz
Question: Which file list command option allows you to view the file size of the software package stored in the /var/tmp directory?
Answer: Use the detail command option to show the file size of the local software package:
lab@srxA-1> file list detail /var/tmp/ | match junos
-rw-r--r-- 1 lab wheel 159209811 Apr 11 06:07 junos-srxsme-12.1R1.9-domestic.tgz
Step 3.4
Issue the request system software add /var/tmp/ junos-srxsme-12.1R1.9-domestic.tgz command to upgrade your assigned device. Use the reboot option to automatically perform a system reboot, which is a requirement of the upgrade process. Use the console terminal session to monitor the upgrade process.
lab@srxA-1> request system software add /var/tmp/ junos-srxsme-12.1R1.9-domestic.tgz reboot
