Installing Software Upgrades Using the CLI

Note: This procedure applies only to upgrading one release of the JUNOS Enhanced Services software to another. To upgrade from the JUNOS software to the JUNOS Enhanced Services software, see the JUNOS Enhanced Services Migration Guide.

To install software upgrades on a router with the CLI:

1. Before installing the software upgrade, verify the available space on the compact flash. For information about verifying available compact flash space, see the JUNOS Enhanced Services Release Notes.
2. Download the software package as described in Downloading Software Upgrades from Juniper Networks.
3. If you are installing the software package from a local directory on the router, copy the JUNOS Enhanced Services software package to the router. We recommend that you copy it to the /var/tmp directory.
4. To install the new package on the router, enter the following command in operational mode in the CLI:
   user@host> request system software add unlink no-copy source

   Replace source with one of the following paths:

   • For a software package that is installed from a local directory on the router—/pathname/package-name (for example, /var/tmp/junos-jsr-8.5R1.1.domestic.tgz)
   • For software packages that are downloaded and installed from a remote location:
     • ftp://hostname/pathname/package-name

       or

     • http://hostname/pathname/package-name

   By default, the request system software add command uses the validate option to validate the software package against the current configuration as a prerequisite to adding the software package. This validation ensures that the router can reboot successfully after the software package is installed. This is the default behavior when you are adding a software package.

   The unlink option removes the package at the earliest opportunity so that the router has enough storage capacity to complete the installation.

   (Optional) The no-copy option specifies that a software package is installed, but a copy of the package is not saved. Include this option if you do not have enough space on the compact flash to perform an upgrade that keeps a copy of the package on the router.

5. After the software package is installed, reboot the router:
   user@host> request system reboot

When the reboot is complete, the router displays the login prompt.
