More details in Wikipedia.
Infrastructure services

LAN
A local area network (LAN) is a computer network that interconnects computers within a limited area such as a home, school, computer laboratory, or office building, using network media. The defining characteristics of LANs, in contrast to wide area networks (WANs), include their smaller geographic area, and non-inclusion of leased telecommunication lines. More details in Wikipedia.

LLDP
The Link Layer Discovery Protocol (LLDP) is a vendor-neutral link layer protocol in the Internet Protocol Suite used by network devices for advertising their identity, capabilities, and neighbors on an IEEE 802 local area network, principally wired Ethernet. The protocol is formally referred to by the IEEE as Station and Media Access Control Connectivity Discovery specified in standards document IEEE 802.1AB. More details in Wikipedia
MAC address
A media access control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. MAC addresses are used as a network address for most IEEE 802 network technologies, including Ethernet and WiFi. Logically, MAC addresses are used in the media access control protocol sublayer of the OSI reference model. More details in Wikipedia.

NDP
The Neighbor Discovery Protocol (NDP) is a protocol in the Internet protocol suite used with Internet Protocol Version 6 (IPv6). More details in Wikipedia
Network Discovery
Network investigation in order to find new nodes. There are 2 types of discovery: active and passive. In passive mode, information about new hosts and devices obtained from ARP tables and routing tables of already known devices. In active discovery mode, NetXMS server will send an ICMP echo requests to all IP addresses in given range, and consider each responding address for adding to database.
Network Map
Visual representaion of network topology.
NetXMS Agent
NetXMS daemon that is installed on monitored Node to provide additional monitoring options.

Object that represents server or device.

Configurable operation that can be executed on Node.
Package Manager
View that manages update packages for NetXMS agents.
Perspective
A perspective defines the initial set and layout of views in the Eclipse Workbench window.
Policy
Configuration parameter set that can be applied on a Node.
Polling
Polling is process of gathering information by server from nodes. This is usually done automatically at specified intervals of time, but can be triggered manually also. There are different types of polling: Status, Configuration, Topology, Discovery and Routing.
Proxy Agent
NetXMS Agent capable of forwarding requests to nodes which are not directly accecible to NetXMS server. Agent support proxying of native agent protocol as well as SNMP.

SNMP
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. SNMP is used mostly in network management systems to monitor network-attached devices for conditions that warrant administrative attention. SNMP is a component of the Internet Protocol Suite as defined by the Internet Engineering Task Force (IETF). It consists of a set of standards for network management, including an application layer protocol, a database schema, and a set of data objects. More details in Wikipedia.
SNMP Trap
Asynchronous notification from SNMP agent to SNMP manager. SNMP traps enable an agent to notify the management station of significant events by way of an unsolicited SNMP message. More details in Wikipedia.
STP
The Spanning Tree Protocol (STP) is a network protocol that ensures a loop-free topology for any bridged Ethernet local area network. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them. Spanning tree also allows a network design to include spare (redundant) links to provide automatic backup paths if an active link fails, without the danger of bridge loops, or the need for manual enabling/disabling of these backup links. More details in Wikipedia

VLAN
In computer networking, a single layer-2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them via one or more routers; such a domain is referred to as a virtual local area network, virtual LAN or VLAN. More details in Wikipedia.
VPN
A virtual private network (VPN) extends a private network across a public network, such as the Internet. It enables a computer or network-enabled device to send and receive data across shared or public networks as if it were directly connected to the private network, while benefiting from the functionality, security and management policies of the private network. A VPN is created by establishing a virtual point-to-point connection through the use of dedicated connections, virtual tunneling protocols, or traffic encryptions. Major implementations of VPNs include OpenVPN and IPsec. More details in Wikipedia.
VRRP
The Virtual Router Redundancy Protocol (VRRP) is a computer networking protocol that provides for automatic assignment of available Internet Protocol (IP) routers to participating hosts. This increases the availability and reliability of routing paths via automatic default gateway selections on an IP subnetwork. More details in Wikipedia
Zone
Zone in NetXMS is a group of IP subnets which form non-overlapping IP address space. There is always zone 0 which contains subnets directly reachable by management server. For all other zones server assumes that subnets within that zones are not reachable directly, and proxy must be used. It is used to monitor subnets with overlapping IP address space.
