Before You Begin

Before you configure network interfaces, you need to perform the following tasks:

• Install J-series device hardware. For more information, see the JUNOS Software with Enhanced Services Hardware Guide.
• Establish basic connectivity. For more information, see the Getting Started Guide for your device.
• If you do not already have a basic understanding of physical and logical interfaces and Juniper Networks interface conventions, read Interfaces Overview.

Although it is not a requirement, you might also want to plan how you are going to use the various network interfaces before you start configuring them.
