Note: Even though you are adding the new software, the changes do not take effect until the router has completed rebooting. |
Purpose
As new features become available or as software problems are fixed, you might periodically upgrade the router software.
To upgrade JUNOS software, follow these steps:
Action
Copy the software packages from the server to the router. We recommend that you copy them to the /var/tmp directory, which is on the rotating medium (hard disk) and is a large file system. Use the following CLI command:
- user@host> file copy ftp://username: prompt@ftp.hostname. net/jbundle-package-name/var/tmp/jbundle-package-name
Action
To add new software packages, use the following JUNOS CLI operational mode command:
package-name is the full URL to the file and release-number is the major software release number; for example, 4.2R1. Before the new software is added, the existing software is automatically deleted.
