This document assumes the below:

  •      You are familiar with the sapwalk2 utility.
  •       You have an SNMP walk output file(s) of customer SNMP devices.

If you do not have a SNMP Walk utility or SNMP walk file of a device, please see this article on using Sapwalk2 utility:

Here are steps to simulate customer SNMP devices in your lab.


  1. Download and install the simulator on your Windows machine.


NOTE: If Microsoft Visual C++ 2008 Redistributable (x86) is not installed, please install it separately.


  1. Create a data directory where you place the walk file. For example c:\snmpdata.


  1. Please ensure that you walk file meets the below criteria:


- Was created through the sapwalk2 utility

- All commented lines are removed from the output

- File extension is .sapwalk


  1. Place the walk file to data directory


  1. From a command line run:


C:\Program Files (x86)\SNMP Simulator>snmpsimd --agent-udpv4-endpoint= --data-dir=c:\snmpdata --v2c-arch


Where is the IP address of the Windows machine.

The name of the file will be community name.


NOTE: Windows SNMP Service needs to be shutdown

NOTE: The community string will be the name of the file.

For example, a file test01.sapwalk is in the data directory, so test01 is community name.
