Glossary

The Glossary section defines the terms used in the SNMP Solo environment.

Agent	Implemented SNMP applications in network elements
	(hosts). Agents perform the network management’s
	functions as requested by the network administrator from
	an NMS.
Dry Closure Input	Non-powered contact type inputs—switch, relay contact,
	open-collector.
Dry Closure Output	Form C dry-contact outputs which are common, normally
	open, or normally closed.
EtherNet	Local Area Network technology, originally developed by the
	Xerox Corporation, can link up to 1,024 nodes in a bus
	network. EtherNet provides raw data transfer in a rate of
	10 megabits/sec. with actual throughputs in 2 to 3
	megabits/sec.	using	a baseband	(single-channel)
	communication technique. EtherNet uses carrier sense
	multiple access collision detection (CSMA/CD) that
	prevents network failures when two devices attempt to
	access the network at the same time. LAN hardware
	manufactures use EtherNet protocol; their products may
	not be compatible.
Gateway	A computer that attaches to a number of networks and
	routes packets between them. The packets can be
	different protocols at the higher levels.
IP	Internet Protocol—The		TCP/IP standard	protocol defines
	the IP datagram as the unit of information passed across
	a network.
IP Address	Internet Protocol Address—A 32-bit address assigned to
	hosts participating in a TCP/IP network. The IP address
	consists of network and host portions. It is assigned to
	an interconnection of a host to a physical network.
MAC	Medium Access Control—The network layer between the
	physical and the datalink layers. Specifically, the physical
	(hardware) address exists in this layer.
MIB	Management Information Base—The database, i.e., set of
	variables maintained by a gateway running SNMP.
NC	Normally Closed —Refers to a contact switch that is
	normally closed.
NIC	Network Interface	Controller—The hardware interface to
	the physical connection to the network.
NMS	Network Management Station
