Description
Install a software package or bundle on the device.
We recommend that you always download the software image to /var/tmp only. On EX Series and QFX Series switches, you must use the /var/tmp directory. Other directories are not supported.
Starting in Junos OS Release 23.4R1 for MX Series routers, you can configure the
dual-phase-bootup statement at the [edit system] hierarchy level.
During device upgrades or downgrades, this feature enables a two-step restart process.
If the dual-phase-bootup statement is already configured and committed,
the device picks up the rescue.conf file during any upgrade or
downgrade. The image is then validated against both the rescue.conf
file and the juniper.conf file. An internal commit is performed
post-reboot, with the latest last-run user configuration being committed. While this
configuration is being committed, you cannot make any changes to the configuration.
When you are upgrading to a different release of Junos OS, you usually use the
validate option on this command. The validate
option checks the candidate software against the current configuration of the device to
ensure they are compatible. (Validate is the default behavior when the software package
being added is a different release.) However, there are circumstances under which you
cannot validate the running configuration in this way. One such circumstance is when you
are upgrading to Junos OS with upgraded FreeBSD from Junos OS based on FreeBSD 6.1.
Another such circumstance is when you are updating between different releases of Junos
OS with upgraded FreeBSD, and the newest version of FreeBSD uses system calls that are
not available in earlier versions of FreeBSD.
Therefore, you cannot use the validate option when upgrading to Junos
Release 21.2R1, because this release runs on FreeBSD 12; previous releases with upgraded
FreeBSD run either FreeBSD 10 or 11.
If you are upgrading between releases that cannot use direct validation, you need to
specify one of the following on the request system software add
operational mode command when you upgrade:
-
The
no-validateoption—this option does not validate the software package against the current configuration. Therefore, the current configuration might fail once you upgrade the system. Choose this option for the first time you upgrade a system to the newer version. -
The
validate-on-hostoption—this option validates the software package by comparing it to the running configuration on a remote Junos OS host. Be sure to choose a host that you have already upgraded to the newer version of software. -
The
validate-on-routing-engineoption—(for systems with redundant REs) this option validates the software package by comparing it to the running configuration on a Routing Engine in the same chassis. Use this option when you have already upgraded the other Routing Engine to the newer version.
For information on valid filename and URL formats, see Format for Specifying Filenames and URLs in Junos OS CLI Commands.
Any configuration changes performed after inputting the request system software
add command will be lost when the system reboots with an upgraded version of
Junos OS.
Starting from Junos OS Release 17.2R1, PTX10008 routers do not support the
request system software add command. Starting from Junos OS Release
17.4R1, PTX10016 routers do not support the request system software add
command. Use the request vmhost software add command instead of the
request system software add command on the PTX10008 and PTX10016
routers to install or upgrade the Junos OS software package or bundle on the router. See
request vmhost software add.
When graceful Routing Engine switchover (GRES) is enabled on a device, you must perform
a unified in-service software upgrade (ISSU) operation to update the software running on
the device. With GRES enabled, if you attempt to perform a software upgrade by entering
the request system software add package-name
command, an error message is displayed stating that only in-service software upgrades
are supported when GRES is configured. In such a case, you must either remove the GRES
configuration before you attempt the upgrade or perform a unified ISSU.
Starting with Junos OS Release 15.1F3, the statement request system software
add installs a software package for the guest OS only for the PTX5000 router
with RE-DUO-C2600-16G, and for MX240, MX480, and MX960 routers with
RE-S-1800X4-32G-S.
Starting with Junos OS Release 15.1F5, the statement request system software
add installs a software package for the guest OS only for the MX2010 and
MX2020 routers with REMX2K-1800-32G-S.
On these routers, in order to install both Junos software and host software packages,
use the request vmhost software add command.

Additional Information
Before upgrading the software on the router or switch, when you have a known stable
system, issue the request system snapshot command to back up the
software, including the configuration, to the /altroot and
/altconfig file systems. After you have upgraded the software on
the router or switch and are satisfied that the new package or bundle is successfully
installed and running, issue the request system snapshot command again
to back up the new software to the /altroot and
/altconfig file systems.
The request system snapshot command is currently not supported on the
QFabric system. Also, you cannot add or install multiple packages on a QFabric
system.
After you run the request system snapshot command, you cannot return to
the previous version of the software because the running and backup copies of the
software are identical.
If you are upgrading more than one package at the same time, delete the operating system package, jkernel, last. Add the operating system package, jkernel, first and the routing software package, jroute, last. If you are upgrading all packages at once, delete and add them in the following order:
user@host> request system software add /var/tmp/jbase user@host> request system software add /var/tmp/jkernel user@host> request system software add /var/tmp/jpfe user@host> request system software add /var/tmp/jdocs user@host> request system software add /var/tmp/jroute user@host> request system software add /var/tmp/jcrypto
By default, when you issue the request system software add
package-name command on a TX Matrix primary Routing
Engine, all the T640 primary Routing Engines that are connected to it are upgraded to
the same version of software. If you issue the same command on the TX Matrix backup
Routing Engine, all the T640 backup Routing Engines that are connected to it are
upgraded to the same version of software.
Likewise, when you issue the request system software add
package-name command on a TX Matrix Plus primary
Routing Engine, all the T1600 or T4000 primary Routing Engines that are connected to it
are upgraded to the same version of software. If you issue the same command on the TX
Matrix Plus backup Routing Engine, all the T1600 or T4000 backup Routing Engines that
are connected to it are upgraded to the same version of software.
Before installing software on a device that has one or more custom YANG data models added to it, back up and remove the configuration data corresponding to the custom YANG data models from the active configuration. For more information see Managing YANG Packages and Configurations During a Software Upgrade or Downgrade.

Release 7.4.
sfc option introduced in Junos OS Release 9.6 for the TX Matrix Plus
router.
set [package-name1package-name2]
option added in Junos OS Release 11.1 for EX Series switches. Added in Junos OS Release
12.2 for M Series, MX Series, and T Series routers.
On EX Series switches, the set
[package-name1package-name2] option
allows you to install only two software packages on a mixed EX4200 and EX4500 Virtual
