1.2 CB3000 Client Bridge Operational Principles
To improve CB3000 Client Bridge management and performance, users need to understand basic network
operating mode functionality and configuration options. These topics are described in the following sections:
•
CB3000 Client Bridge Network Operating Modes
•
Media Access Control (MAC) Layer Bridging
•
DHCP Support
•
Modulation
•
Web Management Support
•
Wireless Security Support
1.2.1 CB3000 Client Bridge Network Operating Modes
The CB3000 Client Bridge can be configured to operate in two different modes depending on the needs of
the network. Select the CB3000 Client Bridge operating mode based on device inter-operability requirements
and network conditions (DHCP support, security settings, etc.)
The CB3000 Client Bridge supports the following network modes:
•
Infrastructure Mode
•
Ad-hoc (Peer-to-Peer) Mode
1.2.1.1 Infrastructure Mode
In infrastructure mode, the CB3000 Client Bridge connects to a LAN through a wireless access point. Ethernet
client devices, such as PCs, printers, POS devices, and other Ethernet-capable devices connect to the CB3000
Client Bridge, either directly, or through a hub or switch.
The CB3000 Client Bridge associates with a nearby access point which sees the CB3000 Client Bridge and
its client devices as a standard mobile unit (MU). The access point then forms a wireless bridge between the
wired LAN and clients through the CB3000 Client Bridge.
The access point is a dedicated device wired into the LAN backbone, while the CB3000 Client Bridge can be
physically moved throughout the LAN. However, the CB3000 Client Bridge is designed to be placed in a single
location for optimal use.
WARNING! Do not connect a Client Bridge set to Infrastructure
mode directly to the LAN (for example, through a wall port). Such
a connection could cause a transmission loop between the client
bridge and access point, disrupting network operation.
