Network Management SNMP Simulator


SimpleAgentPro® is a Network Management SNMP Simulator with an easy to use GUI that can simulate an entire network of LAN-WAN components made up of thousands of manageable devices. 

Used by many of the leading network management vendors including HP, CA, BMC, IBM and Cisco, SimpleAgentPro SNMP simulator has become the industry standard for network management simulation all over the world.

Using this tool, management application, AIOps vendors and system integrators can quickly develop, test and demonstrate management applications without requiring thousands of expensive and bulky hardware boxes.

Enterprise Level simulations, made up of thousands of devices, can be distributed over multiple servers and still controlled from one user interface.

Simplesoft SNMP Simulator

Simulated devices support a variety of network management protocols like:

SNMP V1, V2c and v3NetconfTL1CoAP
Telnet/CLIFTP Client And ServerIPMI var 1.5/2.0MQTT
SSHREST and SOAP Over HTTP/sNetflow (5,7,8,9), IPFix, sFlowModbus over TCP
HTTP/HTTPsTFTP Client and ServerVMware vSphere API callsBACnet/IP

Each simulated device can support its own MIBs, data, and IP Address. SimpleAgentPro’s unique ability to create default variables from MIB or simply learn variables from an existing agent and its built-in support for dynamic values allows it be setup quickly. The use of Tcl based scripting allows for advanced modeling of agent behavior, trap generation, creation of error scenarios and expression of inter-relationships between MIB variables..


The SimpleAgentPro SNMP Simulator is available on a variety of platforms (Linux and Windows), from high end workstations to laptop PCs. It can even run on the same machine that runs your management application, to create a self-contained development and demonstration environment. The device simulation files are ASCII files and can be shared by everyone in the organization. Engineering and Testing departments can use them on UNIX/Win machines, while Sales and Marketing departments can use the same files on Windows laptop PCs. For use in the Cable Industry, an easy to use, Cable Wizard interface is also provided to quickly simulate thousands of CM/MTAs. This can be used to carry out pre-deployment and error scenario testing of the provisioning and management software.


A few simple steps are required to start the SimpleAgentPro. They are:

  1. Use the built in MIB compiler to load the MIBs supported by the Agent.
  2. Use the built in MIB Instance creator to define the variables to be supported or use the MIB learner to learn them from an existing agent or simply select from pre-existing devices in the device library.
  3. Edit the instance and value information if required. Valid defaults are automatically created. The SimpleAgentPro is now ready to receive SNMP Get/GetNext/GetBulk/Set requests and send replies. Simply repeat the above steps for each additional device to be simulated, or simply “clone” the added device.
  4. Use Tcl based scripts to emit any selected trap on demand.

SNMP VersionsSupports SNMPv1, SNMPv2c, and SNMPv3
Netflow, sFlow, IPFIXSimulated devices can create Netflow version 5, 7, 8 and 9 packets and send them to one or more Netflow collectors. The flows sent can be specified to be fixed or dynamic changing. Experimental support for IPFIX and sFlow also present.(part of separately priced Flow module.)
IPMI ver 1.5/2.0Simulated devices can respond to IPMI queries in addition to SNMP and Telnet. IPMI learning can also be done from within SimpleAgentPro and a separate IPMI learner application is also included. IPMI ver 2.0 support is available in the AES version as it uses AES-128 for encryption.
Telnet/CLISimulated devices can respond to Telnet/CLI queries in addition to SNMP and TL1. Telnet/CLI learning can also be done from within SimpleAgentPro. A separate Telnet learner application is also included.
SSHUsers can login to simulated devices via SSH and access the CLI interface. CLI interface used in Telnet is also available via SSH with some export restrictions. Note: SSH is only available on Linux.
HTTP/HTTPsSimulated devices also respond to http and https requests from a web browser. A separte http learner application is also included.
TL1Simulated devices can respond to TL1 queries in addition to SNMP and Telnet/CLI.
TFTPSimulated devices can act as TFTP servers as well as TFTP clients.
FTPSimulated devices can act as FTP servers (only available on Linux) as well as FTP clients.
DHCPSimulated devices can make requests for IP addresses sequentially and in parallel.
SOAP over HTTP/sSimulated devices can respond to SOAP requests over HTTP/s based on information in SOAP modeling file. The modeling file can be created from WSDL documents or by parsing WireShark captures.
REST over HTTP/sSimulated devices can respond to REST requests over HTTP/s based on information in REST modeling file or RequestResponse file. The modeling file and request_response file can be created from learnt interaction with a real device.
