Installing Software Upgrades with the CLI

To install software upgrades on a router using the CLI:

1. Using a Web browser, follow the links to the following download URL on the Juniper Networks Web page. Choose either Canada and U.S. Version or Worldwide Version.
   • https://www.juniper.net/support/csc/swdist-domestic/
   • https://www.juniper.net/support/csc/swdist-ww/
2. Log in to the Juniper Networks authentication system using the username (generally your e-mail address) and password supplied by Juniper Networks representatives.
3. Download the software to your local host.
4. Install the new package on the router:
   user@host> request system software add validate unlink reboot source

   Replace source with one of the following:

   • /pathname/package-name—For a software package that is installed from a local directory on the router.
   • For software packages that are downloaded and installed from a remote location:
     • ftp://hostname/pathname/package-name
     • http://hostname/pathname/package-name

   The validate option validates the software package against the current configuration as a prerequisite to adding the software package to ensure that the router reboots successfully. This is the default behavior when the software package being added is a different release.

   The unlink option removes the package at the earliest opportunity in order to make room to complete the installation.

   Adding the reboot command reboots the router after the upgrade is validated and installed. When the reboot is complete, the router displays the login prompt.

   Rebooting occurs only if the upgrade is successful.
