Media Access Control (Mac) Layer Bridging - Motorola CB3000 User Manual

1-4 CB3000 Client Bridge User's Guide
1.2.1.2 Ad-hoc (Peer-to-Peer) Mode
The Ad-hoc (Peer-to-Peer) mode allows two or more CB3000 Client Bridge units to communicate exclusively
with one another without using an access point. In the simplest of terms, this mode uses the CB3000 Client
Bridge to bridge two or more Ethernet devices.
In Ad-hoc mode, all client devices bridged with the CB3000 Client Bridge share the same subnet and have
identical configurations. More specifically, the wireless LAN service area, channel selection, data preamble
settings, and security settings are required to be the same for the units to communicate.

1.2.2 Media Access Control (MAC) Layer Bridging

Like other Ethernet devices, the CB3000 Client Bridge has a hardware factory encoded address called a MAC
address. The address consists of a 48-bit number written as six hexadecimal bytes separated by colons.
The CB3000 Client Bridge maintains a list of up to 16 Ethernet clients using their unique MAC address. This
information is stored in the CB3000 Client Bridge. This information is used to determine which device in the
device's subnet is receiving or sending data and the appropriate action taken.
