Manager

A node that collects network management information from agents.

Management station

A station that collects network management information from probes.

MAU (Medium Attachment Unit)

The assembly used to provide the physical connection and access to a LAN. It is the device on the LAN that detects collisions. (A transceiver is also called a MAU in the IEEE 802.3 standard.)

MIB (Management Information Base)

A data structure used for communication and control of the probe.

NetMetrix

NetMetrix refers to the HP OpenView NetMetrix/UX software suite for HP-UX and Solaris.

Node

A computer or other addressable device on a network, including PCs, terminals, probes, routers, and mainframes. Usually, a node has a station address.

Object

Any device that can be monitored or controlled by use of the SNMP protocol.

Packet

A bit stream consisting of predefined fields that contain data, addresses, and control information. In the IEEE 802.3 environment, this structure is often referred to as the MAC frame. Packet is used in the Ethernet environment and is used in this guide because it is the more commonly understood term. Different protocols have different packet and frame specifications.

Private MIB

A proprietary MIB that has variables which are used for probe configuration and control options.
