Welcome to SPECTRUM!

Aprismas SPECTRUM is an enterprise-wide network management solution providing multi-vendordevice management. This book is a starting point for network administrators who are first-timeSPECTRUM users. First, well look at SPECTRUMs file structure then, after a brief look at howSPECTRUM works, this book takes you through several task-oriented modules designed to acquaint youwith SPECTRUMs network management features. After completing all the modules, you will be able to:

Start and stop SpectroSERVER and SpectroGRAPH

Manually create a device (router) model

Use AutoDiscovery to automatically model your network

Create a user model

The following books will help you continue developing skills for using SPECTRUM to manage your

network: How to Manage Your Network with SPECTRUMcovers everyday tasks involved in managing your

network with SPECTRUM.

Distributed SpectroSERVERand Database Managementcover specific SPECTRUM features ingreater depth.

Caution:Caution:

Do Not use this book if you are modeling your network using SPECTRUMs DistributedSpectroSERVER (DSS) feature and have not yet partitioned your network into uniquely identifiedlandscapes. Refer to DistributedSpectroSERVERto learn more about modeling using DSS.


5/35


Perform the modules in the sequence presented. You may stop at the end of any module. Simply exitfrom SpectroGRAPH using the Exit option from the File menu at the top left corner of the screen. TheHelp menu in the upper right corner provides access to documents with more detailed information.

How SPECTRUM WorksSPECTRUMs design is based on a client/servermodel. The server, SpectroSERVER (or VNM Virtual Network Machine), includes the

SPECTRUM database and provides security,modeling capabilities, and device managementfacilities. SpectroSERVER supports a suite ofclient applications through its Application

Pr

ogram Interface (SSAPI). The first clientapplication you will see when you startSPECTRUM is SpectroGRAPH.

SpectroGRAPH provides the graphical userinterface that you will use to monitor your

network and launch other client applications.SpectroGRAPHs views contain a variety of iconsthat represent the different elements of yournetwork, including devices, users, and conceptual elements such as LAN segments. Each icon presentsstatus information and provides access to management facilities specific to the network element itrepresents. The information presented by an icon is retrieved from a corresponding model that is

maintained in the SpectroSERVER database.

SPECTRUMs Device Communications Manager (DCM) provides the mechanism for retrieving deviceinformation and managing devices on your network. The DCM periodically polls each device to retrieveup-to-date device status that is saved in the database. The DCM is also the mechanism for network

element management. For example, administrative changes that you make to a device model shown in aSpectroGRAPH view, such as enabling or disabling a port, are interpreted by SPECTRUM and sent to thedevice via the DCM where the administrative action is executed. The device status is updated in thedatabase and the new administrative status is presented in the view.

SPECTRUM Intelligence is implemented as Inference Handlers that add value to the data collected.Inference Handlers are capable of computing useful statistics, such as packets per second. They are alsocapable of interpreting the information collected from individual devices and presenting diagnosticinformation that can help you isolate and respond to network problems.

Inference Handlers depend on an accurate network model in the SpectroSERVER database to effectivelyanalyze the data collected. This book will help you create an accurate modelof your network. The basicnetwork model that well create will consist of models for each of your networks devices and User models

for your administrative and operational users. Later, you can expand your network model by creatingadditional device models, models for campus facilities, such as buildings and wiring closets, and modelsfor users and organizational groups.


7/35


The SpectroSERVER DatabaseSPECTRUM collects a significant amount of information. Some information is collected as SPECTRUM

polls network devices; some is collected from other SpectroSERVER management domains, calledlandscapes. This data is stored in the SpectroSERVERs Events/Statistics database as events andstatistics. Events record information such as changes to a devices operational state, while statisticsrecord data, such as total packets and total collisions. The Distributed Data Manager (DDM) providesfacilities for reducing and saving the information gathered and distributing information in a variety offormats across multiple landscapes and to external applications.

DDMsArchive Manager retrieves event and statistical data from the SpectroSERVER, reduces it, andstores it in the Events/Statistics database. Some overlap is maintained between the two databases toassure an accurate record of events and statistics in case of a system failure.


8/35


Database MaintenanceBacking up your database regularly is the foundation of sound database management. A reliable backupcopy of your database can help you restore database integrity following system interruptions.

SPECTRUM provides two methods for backing up your database. The first, On-Line Backup lets you saveyour database automatically, at regular intervals, or on demand, while SpectroSERVER is running.Alternately, the SPECTRUM Control Panel provides facilities for manually saving and restoring yourdatabase, but requires shutting down SpectroSERVER. To learn more about these features, refer to Database Management.

Model Types, Models and Relations

The SpectroSERVER database provides storage for specific device configurations, statistics and events.The database also contains the Modeling Catalog (model types and relations) that determines thestructure for all network information.

Model types serve as templates. They define characteristics (attributes) of the elements that makeup your network such as workstations, hubs, networks, and users. The modeling catalog containsmodel types that correspond to the device types found in your network. These device model types

provide a template for device-specific information together with the Inference Handlers needed tohelp you manage your network.

AModel represents a particular instance of a model type. Models arenot part of the modeling catalog, but instead, they are created from themodel types provided by the modeling catalog.

For example, to create amodelof a particular SPARCstation 20workstation in your network (identified by a unique hostname and IPaddress), you would choose the Host_SUN model type as a templatefrom the available model types in the modeling catalog. Before creatingthe model, SPECTRUM asks you to identify the particular workstationby supplying a unique IP address or hostname. This informationuniquely identifies the new model as a particular SPARCstation 20.

Host_SUN

192.118.52.34

This modelof themodel type, Host_SUN

is uniquely identified by the

IP address, 192.118.52.34.


10/35


Relations (Connects, Contains, Owns, etc.) definethe relationships that can exist between two or

more models. The type of relations that a particularmodel is capable of are determined by the modeltype used to create a model. For example, a modelcreated from the Networkmodel type can Containavariety of network devices (routers, bridges,workstations, etc.) including specific networkmodels such as FDDI_Networks, ATM_Networks,

etc. Relations define the structure in your networkmodel.

SPECTRUM IconsNetwork elements and organizational entities are

represented in SPECTRUMs views as icons. To the leftare some of the icons youll find there. Icons alert you tonetwork problems and provide access to a variety ofconfiguration and information views. Each icon is uniqueto a particular model type.

Two models were created during SPECTRUM installation:

a User model for the target user identified duringinstallation and a VNM model that represents yourSpectroSERVER. When you first start SPECTRUM, theVNM icon, is the only icon that is visible. The VNM iconprovides access to views that can help you configure andmanage SpectroSERVER functions. User models

determine who is allowed access to SPECTRUM. Youll learn more about User models later in this bookwhen you create User models for other users that will need to access SPECTRUM.

Relationsestablish the structure of your

network model allowing SPECTRUM to

correctly isolate problems.

Icon Double-Click ZonesIcons are configured with double-click zones,

areas that, when double-clicked using the mousepointer, perform a specific action such as openinga view.

The Performance double-click zone is capable ofplotting the performance of three device attributes,as shown here and throughout this book:

Blue - Frame Rate

Green - Load

Orange - Error Rate

When SPECTRUM is first installed, the icon graphs are disabled (by default) and the Performancedouble-click zone is blank. (Refer to Getting Started with SPECTRUM for Operatorsto see an example

of icons with graphs disabled.) You can enable icon graphs by setting the displayGraphOnIconsresource to true in the spectrum resource file in the app-defaults directory within the SPECTRUMinstall area or by highlighting the icon and selecting Show Performance Graph from the Icon Subviewsmenu.

LandscapesA landscape covers the management domain for a given SpectroSERVER. Itincludes a Topology, Location, and Organization model hierarchy. You can createyour entire network model in a single landscape or divide it among severallandscapes. SPECTRUMs Distributed SpectroSERVER (DSS) feature allows youto manage multiple landscapes from the same SpectroGRAPH. Each landscape isidentified by a unique landscape name. Refer to Distributed SpectroSERVERfor

detailed information about using the DSS feature.

SPECTRUM Views

The information from the SPECTRUM databaseis presented within three predefined modelhierarchies. After SPECTRUM is installed, theSpectroSERVER database contains the modelingcatalog and the following models:

World Top level of Location hierarchy

Universe Top level of Topology hierarchy TopOrg Top level of Organization hierarchy

You can create as many levels in each hierarchy,and as many branches at each level, as you needto represent your network. At each level withinthese hierarchies, you can access a variety of

generic views (Model Information, Performance,etc.) and list-type views (Alarms, Events, etc.).At the device level, you can access device-specificviews. The information available in device-specific views is described in ManagementModule Guides for each particular device type.

You will create the other levels of the Topology hierarchy using AutoDiscovery and the instructions inthis book. To create views in the Location and Organization hierarchies, refer to How to Manage YourNetwork with SPECTRUM.

Modeling Your Network

Initially, there are no models in the SPECTRUM database that correspond to devices on your network.The only models that exist in the beginning are the VNM representing your SpectroSERVER and a Usermodel for the administrator who was identified during installation. You need to create a model of yournetwork in the SpectroSERVER database, one that accurately represents your network and allowsSPECTRUM to help you manage your network.

You can useAutoDiscovery, SPECTRUMs automatic modeling feature, to create a model of your

network. For detailed information about AutoDiscovery, refer to theAutoDiscovery Users Guide(0727).

You can also create models manually as shown in the section called To create a model manually:(Page 19).


20/35


Manually Creating a Device Model

In this section we are creating a router model. You can use the same steps to model any device for yournetwork model.

To create a model manually:

1 Navigate into the Universe view:Click on theView menu and selectNew View>Topology.

2 SelectEdit from the File menu to place the viewin Edit mode. SpectroGRAPH has two modes ofoperation: Navigate and Edit. Navigate mode

allows you to move between views. Edit modelets you make changes to a view, such as addingor deleting models. In this case we are adding anew model to the Universe view.

3 SelectNew Model from the Edit menu. TheSelect Model Type dialog box appears.

4 Select a device model type from the Select Model Type dialog box andclickOK.

In our example we are creating a Cisco router and have selectedRtr_Cisco. If your device is not in the list, it may be because SPECTRUMintelligence does not allow it to be modeled at that level in the hierarchy,or that there is no model type for that device. For basic SNMP manage-ment, you can model any device with the GnSNMPDev model type. For

more detailed management, a specific model type is required.A dialog box appears where you can define the specific model you arecreating. Some of the fields are already defined by default. In addition tothe default settings, a minimum definition requires an IP Address andCommunity String. Optional information, such as Contact, Location, etc.can be helpful in managing your network. You can enter the information

here or add it later by editing the models Model Information view.

Note:Note:

Use the New Model by IP selection tocreate a model when you know the IPaddress of the device but not themodel type. SPECTRUM interrogatesthe device to determine the modeltype and automatically creates amodel, using the model type thatmost closely matches the actualdevice.

Reading the Information in SPECTRUM Views

Icons use colors to visually convey

status showing a models Conditionand Rollup Condition. A modelsCondition color alerts you to problemswith the model. Rollup Conditionindicates the status of models at lowerlevels of the hierarchy. As the

SPECTRUM administrator, you can setthe thresholds for Rollup Conditioncolors based on the severity of thecondition of models at the next lowerlevel in the hierarchy.

For example, the rollup threshold for a LAN model might be set to show a Red rollup condition when two

or more devices within it have a Red condition.

Color Condition Meaning

Green Good - Contact established/Normal operation

Yellow Minor Alarm - A situation has occurred but no immediate action is required. This condition is also used for alarms

created only to convey information, such as Duplicate IP.

Orange Major Alarm - A loss of service has occurred or is impending. Action is required within a short period of time.

Red Critical - A loss of service has occurred and immediate action is required.

Gray Unknown - This device cannot be reached due to a known error condition that exists on another device.

Blue Initial - Contact with this device has not yet been established.

Brown Device has been taken off-line for maintenance purposes.

Pipes - Logical Links Between Icons

Network connections are collectively represented as logical links called pipes. A pipe can representmany port-to-port connections. Pipes are created automatically when you create your network modelusing SPECTRUMs AutoDiscovery feature, described earlier in this guide. Pipes can be configured asStandardpipes orLivepipes. (Standard Pipes is the default configuration setting.)

Standard PipesTwo types of standard pipes can be created to showconnections:

Gold pipes show connections that are resolved(connected to an actual port at both ends).AutoDiscovery always resolves connections to a

device port, producing gold pipes. Gold pipescannot be erased from SPECTRUM views.

Silver pipes are manually created by selecting twoicons and choosing the Connect selection from theEdit menu and or by using the mouse to draw aconnection between icons while in Edit mode. If theconnection represented by a silver pipe cannot beresolved, the pipe remains silver. However, if theconnection is resolved, the pipe automaticallyturns to gold. Silver pipes can be erased.

For additional information

on live pipes, refer to Distributed SpectroSERVERandSPECTRUM Icons.

Live pipes use colors to provide additional statusinformation. Within a live pipe, the connection having themost severe condition (bad, disabled, etc.) determines thepipes color. A live pipe can generate an alarm when one of

the links that it represents goes down.

The condition of the individual connectionswithin a pipe is based on the condition of theports at either end of a connection. For

example, if one port is bad and the other isgood the connection has a red condition, andsince red is the most severe condition, the pipewill also be red. The matrix below shows thepossible port condition combinations and theresulting pipe colors.

The initial color of a pipe is blue, indicating anunresolved link (contact not yet established).Once the link is resolved, the pipe displays acolor as listed below.

Pipes are automatically re-created whenever a

pair of previously-piped icons are placed in thesame view. This means, if you remove (cut,destroy, erase) either or both icons of a pipedpair, the pipe is erased. Later, if you place bothpreviously-piped icons in a view, the pipeconnecting them will reappear in the view.

Creating User Models

User models determine who can access SPECTRUM. Minimally, they define each user by user ID andaccess privileges, but additional attributes, such as location, organization, and graphic image of the usercan also be recorded. Only users having a User model in a SpectroSERVERs database are permittedaccess to that SpectroSERVERs landscape, views, and data. If you specified a user name (TargetOwnership) during your SPECTRUM installation, a User model was automatically created for that userID. If other users will need access, you must create User models for them with SPECTRUMs User Editor.

As the Administrator of your network, you can set specific access privileges for each User model that youadd to the database. The Community String entered for each user determines the level of access. Thedefault Community String,ADMIN,0, grants unrestricted administrative privileges. Securityimplementation is beyond the scope of this book, so we are not going to implement a Community Stringthat restricts access. To learn how to apply security, refer to Security and User Maintenance.

Exiting SPECTRUM

Now that you have created a model of your network and added the appropriate users to theSpectroSERVER database, you have completed all the tasks outlined at the beginning of this book,except stopping SpectroSERVER and SpectroGRAPH.

At this point, you can exit from SPECTRUM and the Control Panel or continue exploring SPECTRUMsviews and exit later using the following procedure. SpectroGRAPH, SpectroSERVER, and the ControlPanel were started as separate processes and must be stopped as separate processes.

To Stop SpectroGRAPH:

SelectFile > Exit from the menu bar in any of the SPECTRUM views. All the views will close andSpectroGRAPH will stop.
