Term	Definition
NMS	Network Management System. An interface that provides a method of managing a
	system.
	A network connection endpoint or a common junction for multiple network lines. Nodes
	include:
Node	• Processors.
	• Controllers.
	• Workstations.
O
	Object Identifier. Used by SNMP to identify managed objects. In the SNMP Manager/
OID	Agent network management paradigm, each managed object must have an OID to
	identify it.
OSPF	Open Shortest Path First. A TCP/IP Interior Gateway protocol that calculates the lowest-
	cost route, multipath routing, and load balancing.
P
Packet	Blocks of information for transmission in packet switched systems.
PDU	Protocol Data Unit. A data unit specified in a layer protocol consisting of protocol control
	information and layer user data.
PING	Packet Internet Groper. Verifies if a specific IP address is available. A packet is sent to
	another IP address and waits for a reply.
Policing	Determines if traffic levels are within a specified profile. Policing manages the maximum
	traffic rate used to send or receive packets on an interface.
Port	Physical ports provide connecting components that allow microprocessors to
	communicate with peripheral equipment.
Port Mirroring	Monitors and mirrors network traffic by forwarding copies of incoming and outgoing
	packets from one port to a monitoring port.
	Indicates port speed. Port speeds include:
Port Speed	• Ethernet 10 Mbps.
	• Fast Ethernet 100Mbps.
	• Gigabit Ethernet 1000 Mbps.
PPP	Point-to-Point Protocol. Enables connecting to the Internet over a serial link. PPP
	establishes sessions between a PC and an ISP using the Link Control Protocol (LCP).
Privilege	An authorizations set that performs security-relevant functions, for example, user access
	to a device.
Protocol	A set of rules that governs how devices exchange information across networks.
Protocol Stack	Layered set of protocols working together to provide networking functions.
Q
	Quality of Service. QoS provides policies that contain sets of filters (rules). QoS allows
QoS	network managers to decide how and what network traffic is forwarded according to
	priorities, application types, and source and destination addresses.
Query	Extracts information from a database and presents the information for use.
R
RADIUS	Remote Authentication Dial-In User Service. A method for authenticating system users,
	and tracking connection time.
RDP	Remote Desktop Protocol. Allows a clients to communicate with the Terminal Server over
