SECTION 2 " Features and Functional Overview

The access point functions as a 4-port translating bridge. Functionality within the access point can be partitioned into two major functional blocks: bridging functionality and management functionality. Bridging functions pertain to the forwarding of data through the access point. Management functionality involves configuration, software upgrade, and network management.

Figure 2-2 is a simplified diagram showing the functions within the access point.

Bridging Functionality

General Concepts

Bridges are common components in wired LANs. Bridges are devices that join two or more LAN segments. This provides the appearance of a single LAN segment to the protocols and applications that operate within the LAN.
