SNMP Agent API

• WHAT IT IS
• The Simple Network Management Protocol (SNMP) is
  used to communicate management and diagnostic
  information between network management stations
  and network devices.
• WHAT IT DOES
• SNMP works by sending messages, called protocol
  data units (PDUs), to different parts of a
  network. SNMP-compliant devices, called agents,
  store data about themselves in Management
  Information Bases (MIBs) and return this data to
  the SNMP requesters.
• The API supports SNMP version 1 (RFC 1157.),
  which reports whether a device is functioning
  properly.
