1. Getting started

1.1. About this guide

This guide describes the Nokia SR OS User Plane Function (UPF) in a Broadband Network Gateway (BNG) Control and User Plane Separation (CUPS) system. The BNG CUPS UPF is based on the fundamentals of the BNG and reuses fundamental QoS and forwarding concepts, while moving the control plane handling to the BNG CUPS Control Plane Function (CPF).

For more information about BNG, refer to the 7450 ESS, 7750 SR, and VSR Triple Play Service Delivery Architecture Guide.

For an overview of the BNG CUPS solution and the BNG CUPS CPF, refer to the CMG BNG CUPS Control Plane Function Guide.

This guide is organized into functional chapters that provide concepts and descriptions of the implementation flow, as well as Command Line Interface (CLI) syntax and command usage.

Note:

This guide provides configuration examples based on MD-CLI syntax. For more information about MD-CLI and the commands used to configure the BNG CUPS UPF, refer to the 7450 ESS, 7750 SR, 7950 XRS, and VSR MD-CLI User Guide.

The BNG CUPS UPF also supports configuration using the classic CLI. For more information about the supported classic CLI commands, refer to the 7450 ESS, 7750 SR, 7950 XRS, and VSR Classic CLI Command Reference Guide.

The topics and commands described in this document apply to the following SR OS products:

  1. 7750 SR
  2. VSR

The following chassis types are available for each 7750 SR OS router:

  1. 7750 SR-a4/a8
  2. 7750 SR-1e/2e/3e
  3. 7750 SR-12e
  4. 7750 SR-7/12
  5. 7750 SR-1
  6. 7750 SR-7s
  7. 7750 SR-1s/2s

For a list of unsupported features by platform and chassis, refer to the SR OS 20.x.Rx Software Release Notes, part number 3HE 16194 000x TQZZA.

Command outputs shown in this guide are examples only; actual displays may differ depending on supported functionality and user configuration.

Note:

The SR OS CLI trees and command descriptions have been removed from this guide and can now be found in the following guides:

  1. 7450 ESS, 7750 SR, 7950 XRS, and VSR Classic CLI Command Reference Guide
  2. 7450 ESS, 7750 SR, 7950 XRS, and VSR Clear, Show, and Tools Command Reference Guide (for both MD-CLI and Classic CLI)
  3. 7450 ESS, 7750 SR, 7950 XRS, and VSR MD-CLI Command Reference Guide
