Net-SNMP is a suite of software for using and deploying the SNMP protocol (v1, v2c and v3 and the AgentX subagent protocol). It supports IPv4, IPv6, IPX, AAL5, Unix domain sockets and other transports. It contains a generic client library, a suite of command line applications, a highly extensible SNMP agent, perl modules and python modules.
Simple Network Management Protocol (SNMP) is an Internet Standard protocol for collecting and organizing information about managed devices on IP networks and for modifying that information to change device behavior.
The SNMPv1 SMI defines highly structured tables that are used to group the instances of a tabular object (that is, an object that contains multiple variables). Tables are composed of zero or more rows, which are indexed in a way that allows an SNMP manager to retrieve or alter an entire row with a single Get, GetNext, or Set command.
Network management allows IT professionals to monitor network components within large network area. Access methods include the SNMP, command-line interface (CLI), custom XML, CMIP, Windows Management Instrumentation (WMI), Transaction Language 1 (TL1), CORBA, NETCONF, RESTCONF and the Java Management Extensions (JMX).
Gets its data via an SNMP agent, or through the output of a command line. Typically collects data every five minutes (it can be configured to collect data less frequently). Creates an HTML page per target that features four graphs (GIF or PNG images).
Its most notable applications are remote login and command-line execution. SSH was designed for Unix-like operating systems as a replacement for Telnet and unsecured remote Unix shell protocols, such as the Berkeley Remote Shell (rsh) and the related rlogin and rexec protocols, which all use insecure, plaintext methods of authentication, like ...
An SNMP simulator is a type of computer simulation, that simulates the Simple Network Management Protocol (SNMP) agent. Contrary to network simulation , which models the behavior of a network within a computer, the SNMP simulator actually interfaces with outside systems, for example network management application software.
IP SLA tests and data collection can be configured either via a console (command-line interface) or via SNMP. When using SNMP, both read and write community strings are needed [clarification needed]. The IP SLA voice quality feature was added starting with IOS version 12.3(4)T.
