There are three main techniques used for network mapping: SNMP based approaches, active probing and route analytics.

The Java Dynamic Management Kit ( Java DMK ) provides a set of Java classes and tools that allow easy development of secure monitoring and management solutions based on the Java Management Extensions ( JMX ) specifications and on the SNMP standards.

The foundational OpenView product was Network Node Manager ( NNM ), network monitoring software based on SNMP.

* mbrowse: A graphical SNMP MIB browser for Linux, based upon GTK + and Net-SNMP.

SNMP exposes management data in the form of variables on the managed systems, which describe the system configuration.

Essentially, SNMP agents expose management data on the managed systems as variables.

Application layer protocols such as X. 400 electronic mail, X. 500 and Lightweight Directory Access Protocol ( LDAP ) directory services, H. 323 ( VoIP ), Kerberos, BACnet and Simple network management protocol ( SNMP ) use ASN. 1 to describe the Protocol data units ( PDU ) they exchange.

It can send SNMP requests and dynamically load MIB data.

After collecting the information it will send back the raw data encapsulated in an SNMP protocol.

* Gets its data via an SNMP agent, or through the output of a command line.

For example, when an SNMP query arrives, DMI can fill out the SNMP MIB with data from its MIF.

Common management methods include: a command-line interface ( CLI ) accessed via serial console, telnet or Secure Shell, an embedded Simple Network Management Protocol ( SNMP ) agent allowing management from a remote console or management station, or a web interface for management from a web browser.

Passive fault management is done by collecting alarms from devices ( normally via SNMP ) when something happens in the devices.

An agent has local knowledge of management information and translates that information to or from an SNMP specific form.

The SP3D protocol specification was published by NIST, but designed by the Secure Data Network System project of the National Security Agency ( NSA ), IPsec AH is derived in part from previous IETF standards work for authentication of the Simple Network Management Protocol ( SNMP ).

For example, SNMP protocol can be used to gather the information from devices in the network hierarchy.

Website monitoring service can check HTTP pages, HTTPS, SNMP, FTP, SMTP, POP3, IMAP, DNS, SSH, TELNET, SSL, TCP, ICMP, SIP, UDP, Media Streaming and a range of other ports with a variety of check intervals ranging from every four hours to every one minute.

Rather, SNMP uses an extensible design, where the available information is defined by management information bases ( MIBs ).

In particular, the IETF WGs on IP over Cable Data Network ( IPCDN ) and IP over Digital Video Broadcasting ( DVB ) produced some standards applicable to cable modem systems, primarily in the areas of Simple Network Management Protocol ( SNMP ) Management Information Bases ( MIBs ) for cable modems and other networking equipment that operates over CATV networks.

This MIB has since been split up and can be found in MIBs such as RFC 4293 " Management Information Base for the Internet Protocol ( IP )", RFC 4022 " Management Information Base for the Transmission Control Protocol ( TCP )", RFC 4113 " Management Information Base for the User Datagram Protocol ( UDP )", RFC 2863 " The Interfaces Group MIB " and RFC 3418 " Management Information Base ( MIB ) for the Simple Network Management Protocol ( SNMP )".

* ByteSphere's MIB Database, a free online MIB repository for thousands of SNMP MIBs.

When a fault or event occurs, a network component will often send a notification to the network operator using a protocol such as SNMP.

In typical SNMP uses, one or more administrative computers, called managers, have the task of monitoring or managing a group of hosts or devices on a computer network.

A managed device is a network node that implements an SNMP interface that allows unidirectional ( read-only ) or bidirectional access to node-specific information.

Many common network services are provided such as NTP, SNMP, web server ( Apache ), mail server ( Postfix and Cyrus ), LDAP ( OpenLDAP ), AFP, and print server.

Many common network services are provided such as NTP, SNMP, web server ( Apache ), mail server ( Postfix and Cyrus ), LDAP ( OpenLDAP ), AFP, and print server.

A common usage is to monitor network traffic by polling a network switch or router interface via simple network management protocol ( SNMP ).

Like SNMP and many other network management protocols, it can also be used by attackers to quickly gain detailed knowledge of the network and its machines.

* Monitoring of network services ( SMTP, POP3, HTTP, NNTP, ICMP, SNMP, FTP, SSH )

The use of standards-based mechanisms such as SNMP and Syslog ensures full integration with today ’ s network management systems and provides a unified view of system-wide functionality.

Other systems management approaches are remote shells, proprietary solutions and network management architectures like SNMP.

It can monitor and classify bandwidth usage in a network using SNMP, Packet Sniffing and Netflow.

The standard also defines an alerting mechanism for the system to send a simple network management protocol ( SNMP ) platform event trap ( PET ).

Some network taps offer both duplication of network traffic for monitoring devices and SNMP services.

Most major network tap manufacturers offer taps with remote management through Telnet, HTTP, or SNMP interfaces.

Alternatively, SNMP alarms generated by managed taps can alert network managers to link conditions that merit examination by analyzers to intrusion detection systems.

MacTCP would become a standard part of the Mac OS in 1994, by which time it also supported SNMP and PPP.

Protocols involved may include one or more of SNMP, CORBA, Java RMI,. NET Remoting, Windows Communication Foundation, sockets, UDP, web services or other standard or proprietary protocols.

** Enterprise Managed ( or fully managed ) switches — These have a full set of management features, including CLI, SNMP agent, and web interface.

CMIS / CMIP is most often used in telecommunication applications, in other areas SNMP has become more popular.

Simple Network Management Protocol ( SNMP ) is an " Internet-standard protocol for managing devices on IP networks.

" Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks, and more.

Each managed system executes, at all times, a software component called an agent which reports information via SNMP to the manager.

The variables accessible via SNMP are organized in hierarchies.

SNMP itself does not define which information ( which variables ) a managed system should offer.

Each OID identifies a variable that can be read or set via SNMP.

The SNMP agent receives requests on UDP port 161.

In the Application Layer ( Layer 7 ), the cable modem supports certain protocols that are used for management and maintenance, notably Dynamic Host Configuration Protocol ( DHCP ), SNMP, and TFTP.
