  SNMP: Simple Network Management Protocol Overview (RFC 1155, 1156, 1157)
Simple Network Management Protocol (SNMP) is the protocol developed to manage nodes (servers, workstations, routers, switches and hubs etc.) on an IP network.
A managed device is a network node that contains an SNMP agent and that resides on a managed network.
SNMP is defined by IETF (http://www.ietf.org) through a group of RFCs shown in the reference.

  RFC 1067 (rfc1067) - Simple Network Management Protocol
Network elements are devices such as hosts, gateways, terminal servers, and the like, which have management agents responsible for performing the network management functions requested by the network management stations.
A second goal of the protocol is that the functional paradigm for monitoring and control be sufficiently extensible to accommodate additional, possibly unanticipated aspects of network operation and management.
Protocol Specification The network management protocol is an application protocol by which the variables of an agent's MIB may be inspected or altered.

 [No title]
In the long-term, the use of the OSI network management framework was to be examined.
Scope of Management Information The scope of the management information communicated by operation of the SNMP is exactly that represented by instances of all non- aggregate object types either defined in Internet-standard MIB or defined elsewhere according to the conventions set forth in Internet-standard SMI [5].
Representation of Management Information Management information communicated by operation of the SNMP is represented according to the subset of the ASN.1 language [9] that is specified for the definition of non-aggregate types in the SMI.

 Simple Network Management Protocol
Simple Network Management Protocol (SNMP) is used as the transport protocol for network management.
Network management consists of network management stations communicating with network elements such as hosts, routers, servers, or printers.
The protocol used to communicate between the manager and the network element agent which is SNMP.

 Simple Network Management Protocol - Wikipedia, the free encyclopedia
The SNMP protocol operates at the application layer (layer 7) of the OSI model.
SNMP was approved based on a belief that it was an interim protocol needed for taking steps towards large scale deployment of the Internet and its commercialization.
Simple Network Management Protocol version 2 (RFC 1441–RFC 1452), also known as SNMP v2 or SNMP v2p, revises version 1 and includes improvements in the areas of performance, security, confidentiality, and manager-to-manager communications.

Implicit in the SNMP architectural model is a collection of network management stations and network elements.
Management information communicated by operation of the SNMP is represented according to the subset of the ASN.1 language that is specified for the definition of non-aggregate types in the SMI.
An application that receives SNMP Get, GetNext, GetBulk, and/or Set requests destined for the local system as indicated by the fact that the contextEngineID in the received request is equal to that of the local engine through which the request was received.

 Introduction to the Simple Network Management Protocol (SNMP) Part 1
Some network management suites do not include a client portion of the software and this is where you may need to install and configure a Server’s SNMP Service.
If you want to manage devices from a central location, the SNMP protocol is what facilitates the transfer of data from the client portion of the equation (the device you are monitoring) to the server portion where the data is centralized in logs for centralized viewing and analysis.
SNMP is commonly used to manage devices on a network.

 SNMP - Simple Network Managment Protocol
SNMP is extensible, allowing vendors to easily add network managment functions to their existing products.
SNMP is based on the manager/agent model.SNMP is referred to as "simple" because the agent requires minimal software.Most of the processing power and the data storage resides on the managment system, while a complementary subset of those functions resides in the managed system.
SNMP assumes that the communication path is a connectionless communication subnetwork.In other words, no prearranged communication path is established prior to the transmission of data.As a result, SNMP makes no guarantees about the reliable delivery of the data.although in practice most messages get through, and those that don't can be retransmitted.

 Simple Network Management Protocol (SNMP)
Managed devices are monitored and controlled using four basic SNMP commands: read, write, trap, and traversal operations.
A managed object (sometimes called a MIB object, an object, or a MIB) is one of any number of specific characteristics of a managed device.
An example of a managed object is atInput, which is a scalar object that contains a single object instance, the integer value that indicates the total number of input AppleTalk packets on a router interface.

 CERT Advisory CA-2002-03 Multiple Vulnerabilities in Many Implementations of the Simple Network Management Protocol ...
The Simple Network Management Protocol (SNMP) is a widely deployed protocol that is commonly used to monitor and manage network devices.
Therefore, it may be possible to configure the SNMP agent systems (or the network devices in between the management and agent systems) to disallow request messages from non-authorized systems.
In situations where blocking or disabling SNMP is not possible, exposure to these vulnerabilities may be limited by restricting all SNMP access to separate, isolated management networks that are not publicly accessible.

Also for the sake of simplicity, the SNMP uses only a subset of the basic encoding rules of ASN.1 [10].
