Introduction to the Junos Operating System

Note

The monitor traffic command captures only packets that are local to the device. It does not capture transit packets.

Step 2.5

In preparation for the next lab part, stop the monitor operation using the Ctrl+c keystroke combination, and close the extra terminal session that you opened.

Step 2.6

Return to the original session opened to your device.

From the original session opened to your device, issue the Ctrl+c keystroke combination to stop the continuous ping.

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.

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.

Question: Did the image successfully transfer from the server to the /var/tmp directory on your device?
