Patton electronic SmartNode 4110 Series manual IP context and related elements

SmartWare Software Configuration Guide 9 • IP context overview

Introduction

This chapter outlines the SmartWare Internet protocol (IP) context and its related components. You will get the fundamental understanding on how to set up your SmartNode to make use of IP related services.

The following sections describe the configuration steps necessary to put together certain IP services and the ref- erences to the related chapters that explain the issue in more details.

To understand the information given in the following chapters, carefully read to the end of the current chapter. Before proceeding, make sure that you feel comfortable with the underlying SmartWare configuration concept by reading chapter 2, “Configuration concepts” on page 44.

The IP context in SmartWare is a high level conceptual entity that is responsible for all IP-related protocols and services for data and voice. The IP context performs much the same function as a standalone IP router, and since every context is defined by a name, the IP context is named router by default. This IP context can contain interface static routes, RIP parameters, NAPT, QoS and access control profiles.

In figure 16 on page 115, the IP context with all its related elements is contained within the area on the left, which has a gray fill. The right side displays the related CS context, which communicates with the IP context via different types of gateways. Since the CS context and its related components are not the subject of this chapter, they are illustrated in figure 16 with gray lines instead of black ones.
