Introduction

1.3.1MAC Layer Bridging

The AP listens to all packets on all interfaces and builds an address database using the unique IEEE 48-bit address (MAC address). An address in the database includes the interface media that the device uses to associates with the AP. The AP uses the database to forward packets from one interface to another. The bridge forwards packets addressed to unknown systems to the Default Interface (Ethernet).

The AP internal stack interface handles all messages directed to the AP.

Each AP stores information on destinations and their interfaces to facilitate forwarding. When a user sends an ARP (Address Resolution Protocol) request packet, the AP forwards it over all enabled interfaces (Ethernet, radio and WLAP) except over the interface the ARP request packet was received.

On receiving the ARP response packet, the AP database keeps a record of the destination address along with the receiving interface. With this information, the AP forwards any directed packet to the correct destination. The AP forwards packets for unknown destinations to the Ethernet interface.
