Before You Configure POS

Before you configure a POS interface, verify that you have correctly installed the required module. For information about installing modules in ERX7xx models, ERX14xx models, and ERX310 router, see ERX Hardware Guide, Chapter 4, Installing Modules. For information about installing modules in the E120 and E320 routers, see E120 and E320 Hardware Guide, Chapter 4, Installing Modules. Then verify that no ATM interfaces are defined on the physical port.

Also have the following information available:

• Interfaces specifiers for the POS interfaces that you want to create

  For more information about specifying POS interfaces on E Series routers, see Interface Types and Specifiers in JunosE Command Reference Guide.

• IP addresses and subnet mask assignments for IP interfaces
