    Junos OS Administration Library

    Starting in February 2017, Junos OS documentation is release independent. This means that for any given guide (except release notes), you can find all of the content for all supported releases in one place.

    To determine if a feature is supported by a specific platform or Junos OS release, refer to the Junos OS release notes, Feature Explorer, the new Release History tables in the documentation, and the release information in the CLI content. For more information, see What’s Changed in Junos OS Documentation.


    This guide provides information about configuring essential features that are common across many Juniper devices using Junos OS, including: basic system management features, system log messages, user access, system services, time management, chassis-level properties, Internet protocols, security associations, digital certificates, and Layer 2 network access. Use the topic areas on this page to help you with basic system configuration.
