This software creates a virtual lab consisting of over 100,000 devices for various purposes, including testing, training, and demonstrations. It provides support for various protocols and tools, such as SNMP, TL1, TFTP, FTP, Telnet, and IOS devices with Traps & Informs, Autonomous Msg, Jython script, agent management via RMI, and PDU customization.

The Simulation Toolkit provided by WebNMS includes both Network Recorder and Trap Recorder, which enable the recording and replaying of actual SNMP networks and traps, and create simulations of actual network devices. The software allows the configuration of devices at runtime on both an individual and collective basis. There are many features that can be used to modify device properties like IPv4 or IPv6 address, port number, and MIB values. The software also provides the ability to perform advanced modeling of agent/network behavior and trap generation, as well as customization of SNMP response and request PDUs.
WebNMS Simulation Tool allows for the simulation of more than 100,000 agents simultaneously, making it an ideal tool for scalability testing. It also comes with a trap simulation feature that is useful for fault management testing, configuration of device values, and simulation types for performance testing, behavior simulation for realistic and negative test scenarios across network devices. The software also includes RMI-based network management solution that allows for automated testing. Additionally, it provides a start/stop feature for network simulation at runtime, making it effortless for users to automate network simulation. The easy-to-use GUI makes for a highly productive and efficient network simulation experience. The full-fledged simulation of large networks is possible with WebNMS Simulation Tool.
