MAC Address Learning

MAC Address Learning characterizes a learning bridge, in which the packet’s source MAC address is recorded. Packets destined for that address are forwarded only to the bridge interface on which that address is located. Packets addressed to unknown addresses are forwarded to every bridge interface. MAC Address Learning minimizes traffic on the attached LANs.

MAC Layer

A sub-layer of the Data Link Control (DTL) layer.

Mask

A filter that includes or excludes certain values, for example parts of an IP address.

For example, Unit 2 is inserted in the first minute of

aten-minute cycle, and Unit 1 is inserted in fifth minute of the same cycle, the units are considered the same age.

MD5

Message Digest 5. An algorithm that produces a 128-bit hash. MD5 is a variation of MD4, and increases MD4 security. MD5 verifies the integrity of the communication, authenticates the origin of the communication.

MDI

Media Dependent Interface. A cable used for end stations.

MDIX

Media Dependent Interface with Crossover (MDIX). A cable used for hubs and switches.

MIB

Management Information Base. MIBs contain information describing specific aspects of network components.

Multicast

Transmits copies of a single packet to multiple ports.

N

NMS

Network Management System. An interface that provides a method of managing a system.

Node

A network connection endpoint or a common junction for multiple network lines. Nodes include:

•Processors

•Controllers

•Workstations

O

OID

Object Identifier. Used by SNMP to identify managed objects. In the SNMP Manager/ Agent network management paradigm, each managed object must have an OID to identify it.

P

Packets

Blocks of information for transmission in packet switched systems.
