Overview This section describes the purpose and features of SPECTRUM s Agent Simulator. This section answers the following questions: What is the Agent Simulator? How does the Agent Simulator Work? (Page 7) What Does the Agent Simulator Include? (Page 8) What Else Does This Book Cover? (Page 10) What is the Agent Simulator? The Agent Simulator is a Microsoft Windows based application that lets you implement software simulations of network devices without having the physical devices or infrastructure in place. The simulations can be used in support of all elements in the network service life cycle (i.e., network planning, hardware design, network management design, testing, sales, installation, training, and product support). For example, network engineers can use device simulations to investigate configuration alternatives before committing to solutions. Developers of SNMP applications can use simulations to test their products against network devices they do not have in house or can not afford to obtain. Sales people can give demonstrations of their product on a laptop. Trainers can provide scenarios for classroom demonstration and permit students to gain experience without having to constantly reconfigure equipment. Support personnel can troubleshoot problems with their customer s equipment without having the equipment on hand. Agent Simulator Page 6

Overview How does the Agent Simulator Work? How does the Agent Simulator Work? The Agent Simulator captures device functionality through the following process: Contacts the IP address of the device. Accesses the SNMP agent via a community name match. Queries the supported MIBs to collect attribute state data. This collection of data is referred to as a frame. Creates a DataSet, which can include one frame or multiple frames. Uses a DataSet and an IP address to run any one of a variety of different device simulations. A simulation that is based on a single frame (i.e., a DataSet created by querying the MIBs only once) is considered a static simulation. The Agent Simulator uses the Clone Device Mode to create a static simulation. Because this simulation uses only one snapshot of data, the responses for a given attribute are always the same. This type of simulation may be all that you need for a particular purpose. To make a more active or perhaps more meaningful simulation, it is possible to create a multi-framed DataSet, which results in a simulation that more closely represents changing operational conditions. Two additional modes, Record Device Mode and Characterize Device Mode, produce simulations using multiframed DataSets. Record Device Mode uses as-recorded frames in its DataSet to create a simulation. There are three possible Playback Modes as follows: Freeze Frame continually plays back a single selected frame from the DataSet. This is similar to the static simulation created in the Clone Device Mode. Single Pass runs through all of the frames in the DataSet and then plays back the last frame repeatedly. Agent Simulator Page 7

Overview What Does the Agent Simulator Include? Continuous Loop plays back all of the frames of a DataSet in sequence and then repeats the entire sequence over and over. Characterize Device Mode uses the as-recorded frames of a Dataset to generate a statistical DataSet module whose content represents the anticipated behavior of the device. In operation, the Characterize Device Mode uses statistics exclusively to predict attribute data, thus producing a more animated simulation. As you can see from the above descriptions, you can achieve different levels of simulation to suit different needs. Moreover, through the use of the Agent Simulator s DataSet Editor tool, you can manipulate a DataSet (i.e., simulation) to achieve more explicit results. What Does the Agent Simulator Include? There are multiple Agent Simulator packages available and each package comes with a license that is good for one year. The license controls the number of simulations you can run simultaneously on one host (10, 100, 250, 500, 1000, and Unlimited) but does not limit the number of simulations that you can create. Note: If, for example, you are going to create 1000 simulations but only run 175 at one time, the 250 license would suffice. Depending on which package you choose, the Agent Simulator can incorporate the following software functions: Clone Device is the heart of the product and it lets you create DataSets (i.e., clone devices). Agent Administration lets you run simulations. Record Device lets you collect and store MIB values for a cloned device over a specified number of time intervals. Agent Simulator Page 8

Overview What Does the Agent Simulator Include? Characterize Device lets you collect data by use of statistical algorithms to manipulate the MIB data and cause the cloned device to simulate predicted data. Dataset Administrator lets you obtain the DataSet properties. The Dataset Administrator is useful to copy DataSets from one machine to another to register the DataSets. It can be used to delete registered entries and DataSet files from your PC. Note: The following tools are not discussed in this document in detail. For more information, please refer to the help as specified in each individual section. DataSet Editor lets you manipulate the MIB attributes of a cloned SNMP device in order to change the behavior of the simulation. Also, you can add and delete DataSets. For more information on the DataSet Editor, refer to the on-line help by pressing SHIFT + F1, or use the context sensitive help. MIB Tools utilizes the SNMPv1 protocol to let you view MIBs for an SNMP device. With this tool it is also possible to eliminate selected MIB attributes from the DataSet. For more information on the MIB Tools, refer to the online help by pressing SHIFT + F1. COM Based Scripting lets you invoke and control nearly all of the operations and functionality of the Agent Simulator through the use of scripts prepared in VBScript, Visual Basic, Java, and Perl. For more information on COM Based Scripting, refer to the Scripting documentation. Agent Simulator Page 9

Getting Started This section discusses how to assess your simulation needs, select the types of simulations to use, and start the Agent Simulator. The section contains the following topics: Selecting DataSets and Run Modes Obtaining Additional IP Addresses (Page 17) Starting the Agent Simulator (Page 19) Selecting DataSets and Run Modes Before you begin creating simulations, you need to decide which types of DataSets and Run Modes to use. The following paragraphs provide some assistance in this regard. 1 Clone Device Mode (Static Simulation) This mode is the simplest to run and requires the least amount of CPU and memory resources. Because there is only a single frame of data available, the simulation returns the same operational values for a given attribute each time the simulation runs. This mode would be useful when simulating a simple condition that is not dynamic. 2 Record Device Mode (Multi-Framed DataSets In General) Because this mode uses several frames of data collected over a period of time, its use is desirable when your application requires time varying data. Some examples where this mode may be useful are when showing the graphing or reporting capabilities of a network management system or when you want to recreate a particular problem environment. For example, the event that occurs when an attribute exceeds a certain threshold can be captured and replayed. This mode does require more memory resources than the Clone Device Mode and the size of the DataSet file on disk is larger. Agent Simulator Page 15

Getting Started Selecting DataSets and Run Modes a Record Device Mode > Freeze Frame Playback This playback is somewhat like the Clone Device Mode in the sense that data from a single frame is played back. But with this playback, you can choose which frame in the DataSet to play back. This lets you simulate certain specific network conditions. b Record Device Mode > Single Pass Playback This playback is useful to simulate applications that require time varying data over a specific time interval. c Record Device Mode > Continuous Loop Playback This playback is useful to simulate applications that require several passes through the same time interval to vary data. An example would be a repetitive test or a demonstration that attempts to run continuously. 3 Characterize Device Mode (Statistically Predicted Data) This mode is also useful to simulate applications that require time varying data. The strength of this mode over the other multi-frame modes is that the values of the data are not limited by the range of values collected for the DataSet. This mode gathers statistics on the original data and then uses a data predictor module to predict time-varying data that extends beyond the values collected. Therefore, a simulation run in this mode represents the predicted behavior of the device. The CPU and disk resource usage are more significant than the Clone Device Mode because, the Agent Simulator continuously generates new data samples for all counter attributes. Agent Simulator Page 16

Getting Started Obtaining Additional IP Addresses Obtaining Additional IP Addresses Each simulation you run needs its own IP Address. You need additional IP Addresses configured on your PC to run more than one simulation at a time. However, you can, simulate multiple devices using only one IP Address and run one at a time. Follow the instructions for your operating system: From NT 1 From the Start menu, select Settings > Control Panels > Network. 2 Click on the Protocols tab. 3 Double-click on TCP/IP Protocol. The Microsoft TCP/IP Protocols Screen displays. 4 Click Advanced. The Advanced IP Addressing Screen displays. This allows you to add IP Addresses. 5 Click Add. The TCP/IP Address Screen displays. 6 Enter the IP Address and Subnet Mask. 7 Click Add. 8 If you wish to add more IP Addresses, repeat steps 6 and 7. Note: See your Local Network Administrator to obtain additional IP Addresses. 9 Reboot your PC. Agent Simulator Page 17

Getting Started Starting the Agent Simulator Starting the Agent Simulator There are two ways to start the Agent Simulator, from the Command Line, or from the directory where it was installed. From the Command Line Select Start > Program> SPECTRUM Agent Simulator > SPECTRUM Agent Simulator. The SPECTRUM Agent Simulator Screen displays. From the Directory 1 Go to the directory where the sim4_0.exe executable was installed, C:\Program Files\Aprisma\SPECTRUM Agent Simulator\bin. 2 Double-click on the simmgr.exe executable. The SPECTRUM Agent Simulator Screen displays. Agent Simulator Page 19

Creating Simulations This section provides procedures for creating various types of simulations. The procedures for creating simulations are provided as follows: Clone Device Mode (Page 21) provides step-by-step procedures for creating a static simulation, which is based on a snap shot of the values in the queried MIBs. Record Device Mode (Page 23) provides step-by-step procedures for creating simulations that are based on actual MIB attribute values recorded at different time intervals. Characterize Device Mode (Page 28) provides step-by-step procedures for creating animated simulations that are based on statistically predicted values of MIB attributes. Tip: If this is your first time using the Agent Simulator or if you are unfamiliar with its windows and included fields, refer to the online help or context sensitive help by pressing SHIFT + F1. Agent Simulator Page 20

This window displays the SNMP communication statistics. It counts the number of gets, sets, and getnexts of the running agents. This can be used with any type of DataSet (clone, record, or characterization). The purpose of this screen is to show the clients of the running agents. This is useful to notify the clients in case the simulation is being shutdown. Agent Simulator Page 38

Agent Administration Animate Mode Animate Mode This mode allows you to play back a characterized device. It differs from a recorded device in that the simulation will predict future data based on statistics gathered during the characterization process. Preparation The device must be characterized (see Characterize Device Mode on Page 28) before you can animate it. Procedure Access the Agent Administration tab (Figure 6 (Page 32)) and perform the following steps. 1 Click Start. The Select Simulator Parameters window (Figure 7 (Page 34)) displays.

This brings up Figure 10, Finding the.dat File, which displays a list of.dat files. 4 Select a.dat file and click Open. The Finding the.dat File window closes. The Select Simulator Parameters Window displays. Agent Simulator Page 39

Agent Administration Animate Mode Figure 10: Finding the.dat File 5 Since you have chosen animate, the Zero Counters option is now highlighted. This tells the algorithm to restart the count from zero. If not selected, the counters will start from the point at where you collected the data. 6 Click OK. The Agent Administration tab displays. 7 Enter the IP Address to use for the simulation. This is NOT the IP address of the device, but rather an IP from your machine. 8 This device can now be modeled in SPECTRUM using the IP address you assigned to the device. Agent Simulator Page 40

Managing DataSets This section describes how to manage DataSets using the DataSet Administrator. Figure 11 displays the DataSet Administrator Window. You can get to this window by selecting File > DataSets from the Agent Administration Window (Page 32). The DataSet Administrator is used to manage DataSets on a machine. With this tool it is possible to add, and delete DataSets as well as view and change properties. Figure 11: DataSet Administrator Agent Simulator Page 41

Managing DataSets Animate Mode SETUP is used to view or modify the registration of DataSets (see Figure 12 below). This might be invoked if you want to register a new name to an existing DataSet file (*.mdb). Figure 12: Simulator DataSet Setup SELECT selects the highlighted dataset. IMPORT displays the Select Log File to Import window. Datasets may be created from text files using this feature. There are two file formats currently supported: - Output of Java MibTools - Output of SNMP Walk Utility distributed through SPECTRUM Support This is useful when it is not possible for a customer to obtain or install the SPECTRUM Agent Simulator but has access to one of the other tools mentioned above. Agent Simulator Page 42

Managing DataSets Animate Mode COMPACT compacts the dataset. As datasets are used (opened, closed, modified, saved), they will grow in size. You may want to compact the datasets in order to save disk space. The space savings may be up to 25 %. ADD is used when copying a DataSet from one machine to another. Before the DataSet can be run in a simulation, it must be registered on the local machine using the add command. DELETE allows you to delete a DataSet that is no longer needed. This deletes the DataSet registration on the local machine and optionally deletes the.mdb file. PROPERTIES displays the information at the bottom of Figure 13. This feature is used to display all the properties of a DataSet. The detailed information in this section includes information on when and where the DataSet originated as well as device information like the system descriptor and community name.
