Introduction
Cisco Aironet Access Points are wireless LAN transceivers that can act as the connection point between
wireless and wired networks or as the center point of a standalone wireless network. In large
installations, the roaming functionality provided by multiple access points enables wireless users to
move freely throughout the facility while maintaining uninterrupted access to the network.

Your 1200 series access point can contain two radios: a 2.4-GHz radio in an internal mini-PCI slot and
a 5-GHz radio module in an external, modified cardbus slot. The access point supports one radio of each
type, but it does not support two 2.4-GHz or two 5-GHz radios. You can configure the radios separately,
using different settings on each radio.

The access point uses a browser-based management system, but you can also configure the access point
using a terminal emulator, a Telnet session, or Simple Network Management Protocol (SNMP).

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 for each radio
radio installed in the access point.

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.
