README

lwIP SNMPv2c agent
==================

Based on SNMP stack written by Christiaan Simons <christiaan.simons@axon.tv>

Rewritten by Martin Hentschel <info@cl-soft.de> and
Dirk Ziegelmeier <dziegel@gmx.de>

Features:
  - SNMPv2c support.
  - Low RAM usage - no memory pools, stack only.
  - MIB2 implementation is separated from SNMP stack.
  - Support for multiple MIBs (snmp_set_mibs() call) - e.g. for private MIB.
  - Simple and generic API for MIB implementation.
  - Comfortable node types and helper functions for scalar arrays and tables.
  - Counter64, bit and truthvalue datatype support.
  - Callbacks for SNMP writes e.g. to implement persistency.
  - Runs on two APIs: RAW and netconn.
  - Async API is gone - the stack now supports netconn API instead,
    so blocking operations can be done in MIB calls.
    SNMP runs in a worker thread when netconn API is used.
  - Simplified thread sync support for MIBs - useful when MIBs
    need to access variables shared with other threads where no locking is
    possible. Used in MIB2 to access lwIP stats from lwIP thread.

MIB compiler (code generator):
  - Written in C#. MIB viewer used Windows Forms.
  - Developed on Windows with Visual Studio 2010.
  - Can be compiled and used under Linux with http://www.monodevelop.com/.
  - Based on a heavily modified version of of SharpSnmpLib (a4bd05c6afb4)
    (https://sharpsnmplib.codeplex.com/SourceControl/network/forks/Nemo157/MIBParserUpdate).
  - MIB parser, C file generation framework and LWIP code generation are cleanly
    separated, which means the code may be useful as a base for code generation
    of other SNMP agents.

Notes:
  - Stack and MIB compiler were used to implement a Profinet device.
    Compiled/implemented MIBs: LLDP-MIB, LLDP-EXT-DOT3-MIB, LLDP-EXT-PNO-MIB.

Currently in work:
