snmpsim
SNMP Simulator is a tool that acts as multitude of SNMP Agents built into real physical devices, from SNMP Manager's point of view. Simulator builds and uses a database of physical devices' SNMP footprints to respond like their original counterparts do.
Decision gist · record as of 2026-08-14
Yes. SNMP Simulator is actively maintained, has no known vulnerabilities, installs with low friction, and solves a real problem for anyone testing SNMP-based tools or applications. The permissive BSD license poses no restrictions. Install it if you need to test against SNMP agents without physical devices or if you're developing SNMP client code.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later (supports_current); pysnmp must be installed as the runtime dependency.
- Low friction: pure-Python wheel with a single runtime dependency (pysnmp).
- Actively maintained with a recent release (110 days ago) and ongoing commits.

What it is and what it does
SNMP Simulator is a pure-Python tool that emulates SNMP agents responding to network queries as if they were real devices. It reads simulation data from plain-text files (OID|TYPE|VALUE format), MIB modules, or external sources like SQL databases and network traffic captures, then responds to SNMP v1, v2c, and v3 queries with the configured data. It supports multiple authentication and encryption algorithms, IPv4 and IPv6, and can simulate many agents simultaneously from a single instance.
The package is intended for testing SNMP management tools, developing monitoring solutions, or learning SNMP protocol behavior without needing actual network hardware. You configure it by pointing it to a data directory, optionally capturing real agent responses or MIB definitions to populate the simulation database, then run the responder command to start accepting queries on a specified endpoint.
Use it for
- Test SNMP monitoring and management tools against a controlled, reproducible set of simulated devices.
- Develop and debug SNMP client applications without access to real network equipment.
- Generate SNMP test data by capturing responses from existing agents or MIB files for offline testing.
- Simulate network topology changes and device behavior variations by swapping simulation data files.
- Train or demonstrate SNMP protocol concepts in educational environments without hardware dependencies.
