Upgrading the Junos Software

Core Knowledge

When it comes to security, it is crucial to ensure that you’re running the latest version of software that includes the latest bug fixes and security vulnerability fixes. Running old software in a production environment can be considered risky depending on how the device is exposed.

The installation procedure for Junos is the same across all Juniper platforms. This procedure is fairly simple and requires the use of an FTP or HTTP Server. The easiest way to get your jinstall file to the Juniper device is using a mini HTTP server called HFS. This webserver can be downloaded from Here

As with any upgrade or downgrade procedure you’re going to need the software. When it comes to juniper you must acquire this software from the Juniper Software Downloads section as there is no way to backup software from an Existing Juniper device to a web server or tftp server like you can with Cisco.

For the purpose of this lab we’re going to be upgrade the Junos software on SW1 in the lab which is an EX3200-24T. The Device is currently running 12.1R8.4 and we’re going to upgrade it to 12.3R4.6

You first need to have the jinstall file to complete this procedure and for this procedure we’ll need the “jinstall-ex-3200-12.3R4.6-domestic-signed.tgz” placed into the root directory filesystem on HFS. This can be easily done by right clicking the root directory in HFS and adding the jinstall file by navigating to it in the browser window.

Once the jinstall file is in the web root, you then need connectivity from the http server to the switch. This can be easily done by connecting the management ethernet interface of the EX3200 into the same vlan/subnet as your desktop. Assign the me0.0 interface an IP address and verify connectivity with the desktop using ping. Once connectivity is verified you’re ready to proceed.

The command you’ll be using to upgrade/downgrade the Junos Software on the switch is request system software add “http://192.168.1.5/jinstall-ex-3200-12.3R4.6-domestic-signed.tgz reboot which is executed in user mode. You must have ROOT or super-user rights to perform this procedure. The switch will automatically download the software via HTTP and verify the package and set the environment variables and prompt for a reboot.

If you have already completed the software add step and you want to cancel the pending upgrade/downgrade than all you need to do is perform a request system software delete jinstall in user mode prior to rebooting.

Once the system has rebooted, you will notice that the new software you just requested is now running on the system.

Lab Prerequisites

This lab cannot be completed on Olive of vSRX and must be completed using REAL Juniper Networks hardware. For the purpose of this lab, an EX3200 is used. Prior to starting the lab ensure that you have the jinstall image in the HFS root directory. Example given below;

You need to establish a console session to SW1 and log into the device using the root account or a user account with super-user privileges.

Lab Objectives

To complete this lab you will perform the following objectives;

Before you Continue

It is recommended that you attempt to complete these lab objectives the first time without looking at the Lab Instruction section.

If you are a student preparing for the Juniper JNCIA Certification Exam than you are more likely to remember how to complete these objectives if you attempt to complete them the first time on your own with the use of the core knowledge section found in this lab. You should only resort to the Lab Instruction section to verify your work.

Lab Instruction

The following lab instruction is performed on a Juniper EX3200-24T Switch.

• Configure and Verify connectivity from the Switch to the Web Server
