SNMP library for Python

PySNMP is a cross-platform, pure-Python SNMP engine implementation. It features fully-functional SNMP engine capable to act in Agent/Manager/Proxy roles, talking SNMP v1/v2c/v3 protocol versions over IPv4/IPv6 and other network transports.

Despite its name, SNMP is not a really simple protocol. For instance its third version introduces complex and open-ended security framework, multilingual capabilities, remote configuration and other features. PySNMP implementation closely follows intricate system details and features bringing most possible power and flexibility to its users.

Current PySNMP stable version is 4.3. It runs with Python 2.4 through 3.5 and is recommended for new applications as well as for migration from older, now obsolete, PySNMP releases. All site documentation and examples are written for the 4.3 and later versions in mind. Older materials are still available under the obsolete section.

Besides the libraries, a set of pure-Python command-line tools are shipped along with the system. Those tools mimic the interface and behaviour of popular Net-SNMP snmpget/snmpset/snmpwalk utilities. They may be useful in a cross-platform situations as well as a testing and prototyping instrument for pysnmp users.

PySNMP software is free and open-source. It’s being distributed under a liberal BSD-style license. PySNMP development has been initially sponsored by a PSF grant.
