The Network Simulator provides an integrated, versatile, easy-to-use GUI-based network designer tool to design and simulate a network with SNMP, TL1, TFTP, FTP, Telnet and Cisco IOS devices.
WebNMS Simulation Toolkit presents the Network Simulator to test and demonstrate SNMP, TL1, TFTP, FTP, Telnet and Cisco IOS management applications in a virtual, scalable network environment. Ability to simulate 100,000 devices simultaneously for scalability testing, trap simulation for fault management testing, configuration of device values and simulation types for performance testing, behavior simulation for testing realistic/negative test scenarios across network devices, start/stop of network at runtime, automated network simulation, visualization of network topology and easy-to-use GUI enables full-fledged simulation of large networks.
Features Benefits Multi-Protocol Support
- Complete simulation of SNMPv1, SNMPv2, and SNMPv3 devices. The SNMPv3 agent can respond to v3 requests in addition to SNMP v1/v2c requests.
- Complete simulation of TL1 devices with multiple AID and MPB values, Acknowledgment messages, Output Response Messages, Autonomous Messages, and Jython scripts to simulate behavior.
- Complete support for TFTP server and client and FTP client for individual devices.
- Support for executing Telnet commands in SNMP devices.
- Supports simulation of Cisco IOS Software to simulate Cisco routers and switches, that can be accessed using CLI.
Multiple Agents in one PC
- Integrated Network Designer wizard designs and creates a network simulation with multiple SNMP/TL1/CLI/TFTP/FTP devices at one shot.
- Each device in the network, supports its own MIB/TCS file, read/write community, unique IPv4 or IPv6 Address, port number combination and unique values.
- The number of agents that can be run simultaneously on a single PC is 10000 in Windows, 100000 in Linux. This enables simulation of large enterprise networks.
- Devices can be assigned IPv4 address or IPv6 address.
Simulation of Cisco IOS Software
- Device Library with pre-configured Cisco series Routers and Switches. The devices fully supports SNMPv1, v2, v3; TFTP and Cisco IOS software.
- Cisco IOS commands implemented in User, Privileged, Configuration, Interface configuration, Router and Vlan modes.
- Extensive script APIs for customization of Cisco IOS commands.
- Script Editor to view and edit Cisco IOS command behavior scripts.
- Command Configurator to define new Cisco IOS commands.
Automated Network Simulation
- Network Automation Wizard to automate the most common tasks performed by the network devices.
- Configure tasks to be performed on any device and set hourly/daily triggers to instigate each task.
- Automatic script generation that schedule and trigger the task.
- Topology Editor to establish inter-connections across routers, switches and other devices in the network, through drag and drop.
- Visualize the network topology.
- Disconnect existing connections in the topology.
Record and Replay of Real Networks
- The Network Recorder records any number of target devices simultaneously by providing the starting and ending IPv4 or IPv6 Address.
- The recorded network can be replayed instantly in the Network Designer.
- The recorded configuration can also be suitably modified to re-create problems or test configuration variations.
Record and Replay of Traps
- The Trap recorder records SNMP v1 and SNMPv2c traps by listening for traps at the specified port.
- The recorded traps can be stored in XML files and replayed in the simulator as request-based, threshold-based or time-based traps.
Customization of Agent Values
- The user can customize and control all SNMP and TL1 command responses from the UI or using Jython scripts.
- The Behavior simulation wizard help you to model agent behavior and define inter-relationships among MIB variables, among TL1 commands, and across devices in the network using jython scripts.
- Auto-generation of scripts for selected methods and bulk addition of scripts across network devices makes the behavior simulation wizard more user-friendly and easy-to-use.
- Powerful built-in script APIs enable you to automate a complete network environment.
SNMP PDU Customization
- Supports customizing the request and response SNMP PDU to send garbled/invalid responses to test the SNMP managers' robustness in the event of receiving bad packets.
- The PDU scrambler also provides access to the SNMP script API methods.
Management of Networks through RMI
- The SNMP and TL1 agents in the simulated network can be managed via RMI (Remote Method Invocation) by executing user-defined tasks at runtime. This helps in test case automation of manager applications.
- The RMI client API defines the methods in the simulator, which can be accessed via RMI to programmatically update values for specific devices, add/delete SNMP agents in the network, start and stop individual devices, send SNMP v1/v2/v3 traps and TL1 autonomous messages etc., within the simulated network.
TFTP, FTP and Telnet Support
- TFTP client and server and FTP client is implemented to enable transfer of files between the manager and agents using TFTP and FTP. The file transfer can be done from the Network designer UI. Runtime configurations can be made through scripts and RMI.
- Telnet support for SNMP devices to enable execution of telnet commands on the simulated devices.
- Extensive script APIs for customization of Telnet commands.
- Script Editor to view and edit Telnet command behavior scripts.
- Command Configurator to define new Telnet commands.
Trap/Inform/Autonomous Message Generation
- Support for SNMPv1,v2,v3 Traps and SNMP v2, v3 Informs.
- Supports configuration of SNMP Traps and Informs with varbinds which can be customized to be sent at different scenarios.
- Supports configuration of TL1 Alarm messages with varied combinations of textblocks and severity for a single autonomous code which can be customized to be sent at different scenarios.
- Simulates SNMPv1, SNMPv2 and SNMPv3 error conditions. Jython scripts can be used to configure error conditions and scenarios.
- Simulates TL1 error responses.
Dynamic Configuration of IPv4 or IPv6 Address
- The Network Simulator provides the facility to dynamically configure IPv4 or IPv6 Addresses when starting each agent instance in the network.
- This facility is supported in Windows NT, 2000, XP and Linux OS.
- Individual agents in the network can be started or stopped.
- Devices can be added individually or in bulk
- A device can be copied and pasted in the network
- SNMP and TL1 agent values can be configured individually for each device.
- Real SNMP agents can be recorded for individual SNMP devices in the network.
- Traps/Autonomous Messages can be configured for individual SNMP and TL1 devices in the network.
- Scripts can be configured individually or in bulk.

Packaging and Installing the Network / Devices in Device Tree
- The created network can be packaged and installed with the desired configurations in any location to give demonstrations of management applications or during trade shows.
- The new devices configured in the device library can be packaged and installed with the desired configuration.
- The template based model of device creation and data storage offers the following benefits:
- Enables creation of large networks in seconds.
- Occupies very less storage space of PostgreSQL data for the network devices.
- Enables template based configuration and modification of devices. (i.e) if 50 devices are created using Template device "A", any bulk modifications can be achieved by modifying this template device.
- Offers enhanced network performance.

The Network Simulator offers a simplified and complete network simulation experience. The following diagram depicts this functionality offered by the Network Simulator.
The Network Simulator can design and simulate a network with SNMP, TL1, TFTF, FTP, Telnet and Cisco IOS devices, in four simple steps:
1. Add devices to the Device tree : Add devices with the required configuration to the device tree in the Network Designer. Pre-configured devices are also bundled with the toolkit.
2. Create the Network: Create and add bulk devices to the network, at one shot.
3. Configure the Network devices: Configure the devices in the network, if required.
4. Start the Network : Start the network or start individual agents in the network. The MIB Browser and TL1 Craft Interface test tools, can be used as the manager tools for testing.
