SNMP Library for Python
This is a pure-Python, open source and free implementation of v1/v2c/v3 SNMP engine distributed under 2-clause BSD license.
Features
- Complete SNMPv1/v2c and SNMPv3 support based on IETF RFC standards.
- SMI framework for resolving MIB information and implementing SMI Managed Objects
- Complete SNMP entity implementation
- USM Extended Security Options support (3DES, 192/256-bit AES encryption) based on draft standards and vendor implementations.
- Extensible network transports framework (UDP/IPv4, UDP/IPv6)
- Asynchronous socket-based IO API support via asyncio integration
- PySMI integration for dynamic MIB compilation
- Built-in instrumentation exposing protocol engine operations
- Python eggs and py2exe friendly
- 100% Python, works with Python 3.10+ (tested on 3.10–3.14)
- MT-safe (if SnmpEngine is thread-local)
Features, specific to SNMPv3 model include:
- USM authentication (MD5/SHA-1/SHA-2) and privacy (DES/AES) protocols (RFC3414, RFC7860)
- View-based access control to use with any SNMP model (RFC3415)
- Built-in SNMP proxy PDU converter for building multi-lingual SNMP entities (RFC2576)
- Remote SNMP engine configuration
- Optional SNMP engine discovery
- Shipped with standard SNMP applications (RFC3413)
Download & Install
The PySNMP package is freely available for download from PyPI and GitHub.
Just run:
pip install pysnmp
To download and install PySNMP along with its dependencies:
pyasn1package from PyASN1- If
pysmipackage from PySMI presents, MIB services are enabled. - If
cryptographypackage (43.0.x and above) presents, strong SNMPv3 encryption is enabled.
Make sure you check out other sibling projects of PySNMP from the home page.
