6.2 Bridge Component definitions

6.2.1 Overview

A Bridge Component interconnects two or more network segments and forwards packets between them. This document supports the Bridge Component features listed in 6.2.2, including link speeds of 10 Mb/s to 10 Gb/s.

6.2.2 Bridge Component feature selection

A Bridge Component may support the following features:
