Glossary-2

IEEE 802.1D

Specifies a general method for the operation of MAC bridges,
including the Spanning Tree Protocol.

IEEE 802.1Q

VLAN Tagging defines Ethernet frame tags which carry VLAN
information. It allows switches to assign end-stations to different
virtual LANs, and defines a standard way for VLANs to
communicate across switched networks.

IEEE 802.3ac

Defines frame extensions for VLAN tagging.

In-Band Management

Management of the network from a station that is attached to the
network.

Link Aggregation

See Port Trunk.

MIB

An acronym for Management Information Base. It is a set of
database objects that contains information about the device.

Out-of-Band Management

Management of the network from a station that is not attached to
the network.

Port Mirroring

A method whereby data on a target port is mirrored to an analysis
port for troubleshooting with a logic analyzer or RMON probe.
This allows data on the target port to be studied unobtrusively.
