How to Use the Junos OS Documentation?
Junos OS documentation is release-independent. This means that you will find only one version of Junos OS documentation in the TechLibrary pages on https://www.juniper.net.
You can view what has changed for individual features by release within the documentation pages. In addition, a summary of all changes made to the contents is provided in a Release History Table at the end of the documentation page. To find details about the changes, use the links provided in the Release History Table to navigate to the relevant location in the page.
Frequently Asked Questions
Why is the Junos OS documentation release-independent?
With the release-independent presentation model, the search results will list only one instance of a documentation page instead of showing multiple versions of a similar documentation page for every release. This helps you find the information quickly, and find the changes made for various releases in the same page, without having to navigate to another version of the page. The streamlined search results also reduce the time that you spend navigating through documentation to find the most relevant and accurate information about Juniper platforms and Junos OS features.
