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 3.9+
• 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:

• pyasn1 package from PyASN1
• If pysmi package from PySMI presents, MIB services are enabled.
• If cryptography package (43.0.x and above) presents, strong SNMPv3 encryption is enabled.
