Unreferenced date August 2011 An SNMP Simulator is a type of Computer simulation , that simulates the Simple Network Management Protocol SNMP interface. Contrary to Network simulation , which models the behavior of a network within a computer, the SNMP simulator actually interfaces with outside systems, for example Network Management Application software. An SNMP Simulator fools the Network Management Application software into believing it is talking via the SNMP protocol to one or more devices, just like a Flight simulator allows a pilot to believe they are flying a plane. Uses of SNMP Simulator SNMP Simulators are used for development, testing, training of Network management system software. Before the advent of simulators, actual physical equipment was used. The scalability of simulators dramatically reduce the cost in this area. Features in this area vary widely, from the no cost to commercial offerings. It is not uncommon for higher end simulators to simulate thousands of devices on common PC hardware or virtual machines. Setting up any number of instances of any number of device type is standard functionality. The better simulators will allow to create any type of dynamic scenario, both in terms of MIB object behavior as well as trap generation.

Orphan date February 2009 No footnotes date April 2009 MIMIC Simulator is a product suite from Gambit Communications consisting of simulation software in the network management network and systems management space. MIMIC SNMP simulator solves a classical simulation problem Network Management Application network management software typically manages large networks. Traditionally, in order to set up such networks for the purposes of software development , software testing or training , physical equipment had to be separately purchased and assembled in laboratories . To reduce the expense, most of the network can be simulated. The principle behind Simple Network Management Protocol SNMP simulation is that the SNMP protocol is an interface that can be simulated. SNMP requests carry data values for Management information base MIB objects, which can be shaped at will by the simulator, thus representing any device which has an SNMP interface. In contrast to network simulation , where the entire network is modelled within a computer, this type of empirical simulation is visible on the network, and one can communicate with the simulator over the network. The concept can be extended to other Protocol computing protocols such as for cable modems , command line interface CLI such as Cisco IOS or TL1 , or IPMI .
