Release Notes for Cisco Aironet 340 and 350 Series Access Points and 350 Series Bridges Running Firmware Version 12.00T
OL-3346-01
Introduction
Introduction
A Cisco Aironet Access Point is a wireless LAN transceiver that can act as the connection point between
wireless and wired networks or as the center point of a standalone wireless network. Cisco Aironet
Bridges are wireless LAN transceivers that connect two or more remote networks into a single LAN.

The access point and bridge use a browser-based management system. The system settings are on web
pages in the system firmware. You use your Internet browser to view and adjust the system settings.

Multiple SSID and VLAN Support
Version 12.00T supports multiple SSIDs and VLANs. The multiple SSID feature is active only when
VLANs are enabled. You can use multiple SSIDs to create different levels of network access and to
access virtual LANs (VLANs). You can configure up to 16 separate SSID-to-VLAN pairs on your
network.

What Is a VLAN?
When a switched network is segmented logically by functions, project, teams, or applications, rather
than on a physical or geographical basis, then each logical network segment is called a VLAN. For
example, all workstations and servers used by a particular workgroup team can be connected to the same
VLAN regardless of their physical connections to the network or the fact that they might be intermingled
with other teams. When you logically segment a network into VLANs, you can reconfigure the network
through software rather than physically unplugging and moving devices or wires.

A VLAN can be thought of as a broadcast domain that exists within a defined set of switches. A VLAN
consists of a number of end systems, either hosts or network equipment (such as bridges and routers),
connected by a single bridging domain. The bridging domain is supported on various pieces of network
equipment; for example, LAN switches that operate bridging protocols between them with a separate
group for each VLAN.

VLANs provide the segmentation services traditionally provided by routers in LAN configurations.
Routers in VLAN topologies provide broadcast filtering, security, address summarization, and
traffic-flow management. None of the switches within the defined group bridge any frames, not even
broadcast frames, between two VLANs.
