Simple Network Management Protocol
SNMP (simple network management protocol) SNMP is a set of protocols for managing complex networks. It is one of the most widely accepted protocols to manage and monitor network elements and is an application layer protocol that allows management stations to poll agents running on network devices for specific pieces of information.
  SNMP consists of a SNMP MANAGER, MANAGED DEVICES, SNMP Agent and MIB (Management Information Base). SNMP Manager: The SNMP manager communicates with the SNMP agent implemented network devices. This is typically a computer that is used to run one or more network management systems. SNMP Managers Key Functions include:
Managed Devices: A managed device is a part of the network that requires some form of monitoring and management e.g. routers, servers or workstations.
SNMP Agent: An SNMP agent is a program that is packaged within the network element. It collects the management information database locally from the device and makes it available to the SNMP manager. The SNMP agents key functions are:
MIB (Management Information Base): The SNMP manager uses the database to request the agent for specific information, then translates the information as needed for the Network Management System (NMS). The MIB files are the set of questions that a SNMP Manager can ask the agent. Innovative Energies MIB files can be found here. SNMP Communication: Being the part of the OSI & TCP/IP protocol suite, the SNMP messages are wrapped as UDP (user datagram protocol) and intern wrapped and transmitted using the Internet Protocol. SNMP Commands Include:
