Chapter 1 Introduction This chapter provides an overview of RingView functionality and features. What Is RingView? RingView for FDDI (Fiber Distributed Data Interface) is a SPECTRUM application program that provides enhanced capabilties for modeling and displaying the ring of devices and connections that make up an FDDI LAN. An important feature of the RingView application is that it allows for several different ways of displaying these FDDI nodes within a SPECTRUM Topology view.

How RingView Works How RingView Works In most cases, RingView operations are initially invoked by AutoDiscovery and are thus transparent to the user. If the IP address range you specify for an AutoDiscovery session includes a discrete FDDI LAN, AutoDiscovery will automatically create a model for the LAN and then activate the RingView application, which will attempt to model the LAN’s contents. This is accomplished in one of two ways.

Chapter 2 The RingView Modeling Process This chapter describes the methodolgy used by the RingView application to determine the topology of an FDDI LAN. Basic Steps The process RingView uses to determine the topology of a given ring is the same whether the application is invoked automatically by AutoDiscovery or manually through the “Discover Ring” button in the RingView Tools dialog box (see Chapter 3). In either case, the first step is to determine which existing models are part of the ring.
Use of MAC Addresses Use of MAC Addresses Whichever mapping method is employed (reading a station table or querying individual models about their neighbors), RingView recognizes the existence of a node by its physical or MAC (Media Access Control) address.
Mapping with Non-Manageable Devices Editing GenFDDIMac Information concentrator attached to the dual ring, or it could be an end node (i.e., a singleattached station or concentrator). In other words, the existence of a GenFDDIMac_NM model denotes the unavailability of certain information. Therefore, the more times that creation of a GenFDDIMac_NM model is called for, the less likely it is that RingView will be able to map the ring completely.
Mapping with Non-Manageable Devices Editing GenFDDIMac Information After saving your edits to the GenFDDIMac Information View, you can run RingView again by bringing up the Information View for the FDDI LAN and opening the RingView Tools dialog box (see Chapter 3 for illustration and detailed instructions). The additional information provided by your edits will allow RingView to re-map the ring and generate a more comprehensive topology.

RingView Modeling RingView Modeling Several different model types are used to model the nodes on an FDDI ring. These model types fall into two basic categories: those that represent devices and those that represent managed applications of devices. Device Model Types RingView does not create models of the actual FDDI devices. These models are created manually by a user or automatically by the AutoDiscovery application.
RingView Modeling Managed Application Model Types FddiMAC Used to model the intelligent connection between an MMAC-Plus module and the Flexible Network Bus (FNB) on the backplane of the MMAC-Plus chassis. FddiNoMAC Used to model a non-intelligent connection between an MMAC-Plus module and the Flexible Network Bus (FNB) on the backplane of the MMAC-Plus chassis.
RingView Modeling Managed Application Model Types NOTE RingView-created models of the types described above are represented in Topology views by icons that are labeled DAS, DAC, SAS, or SAC to indicate the connectivity and function of the modeled node (dual-attached station, dual-attached concentrator, single-attached station, or single-attached concentrator).
Chapter 3 The User Interface This chapter explains how to access and operate the dialog boxes that serve as the user interface for the RingView component of SPECTRUM. Accessing RingView Tools Once an FDDI LAN has been modeled in SPECTRUM either manually or through a regular AutoDiscovery session, subsequent discovery sessions can be invoked for that LAN through the RingView Tools dialog box, which is accessed from the FDDI LAN’s Information view (Figure 3-1).

The RingView Tools Dialog Box Discovery Options Discovery Options The Discovery Options panel at the top of the dialog box lets you start a discovery session for the FDDI LAN at any time by clicking on the Discover Ring button. An “Action successful” message box will be displayed to inform you when the discovery session is completed. Click on “Close” to dismiss the message box. The results of the discovery session will then be visible in the FDDI LAN Topology view.
The RingView Tools Dialog Box Display Settings Display Mode This button lets you choose between a non-editable RingView mode and an editable Normal mode. In RingView mode, the display is governed by the RingView software and will show only entities that have been determined to be part of the ring (i.e., no Off-Page Reference icons will appear). Note also that the display is locked. This means the FDDI LAN model can NOT be destroyed, even if it was created manually rather than by RingView.
RingView Displays RingView Displays The following four figures (3-3 through 3-6) show how the same ring would be depicted using each of the four different combinations of FDDI LAN Topology view options selectable from the Display Settings panel of the RingView Tools dialog box. Figure 3-7 shows the DevTop view for the Rtr_CiscoAGS model displayed in Figures 3-5 and 3-6.
