Chapter 1 Overview
File Transfers
In this release, support is being added for the AAA server to return the VLAN number or name using the
standard “RADIUS assigned VLAN name/number” feature defined in IETF RFC 2868 (RADIUS
Attributes for Tunnel Protocol Support). To assign a wireless client to a particular VLAN, the AAA
server sends the following attributes to the controller in the access accept message:
•
IETF 64 (Tunnel Type): VLAN
•
IETF 65 (Tunnel Medium Type): 802
•
IETF 81 (Tunnel Private Group ID): VLAN # or VLAN Name String
This enables Cisco Secure ACS to communicate a VLAN change that may be a result of a posture
analysis. Benefits of this new feature include:
•
Integration with Cisco Secure ACS reduces installation and setup time
•
Cisco Secure ACS operates smoothly across both wired and wireless networks
This feature supports 2100 and 4400 series controllers and 1130 and 1200 series lightweight access
points.
File Transfers
The Cisco UWN Solution operator can upload and download operating system code, configuration, and
certificate files to and from controller using the GUI, CLI commands, or Cisco WCS.
•
To use CLI commands, refer to the
“Transferring Files to and from a Controller” section on
page 8-7
.
•
To use Cisco WCS to upgrade software, refer to the

Power over Ethernet
Lightweight access points can receive power via their Ethernet cables from 802.3af-compatible Power
over Ethernet (PoE) devices, which can reduce the cost of discrete power supplies, additional wiring,
conduits, outlets, and installer time. PoE also frees installers from having to mount Cisco 1000 series
lightweight access points or other powered equipment near AC outlets, providing greater flexibility in
positioning Cisco 1000 series lightweight access points for maximum coverage.
When you are using PoE, the installer runs a single CAT-5 cable from each lightweight access point to
PoE-equipped network elements, such as a PoE power hub or a Cisco WLAN Solution Single-Line PoE
Injector. When the PoE equipment determines that the lightweight access point is PoE-enabled, it sends
48 VDC over the unused pairs in the Ethernet cable to power the lightweight access point.
The PoE cable length is limited by the 100BASE-T or 10BASE-T specification to 100 m or 200 m,
respectively.
Lightweight access points can receive power from an 802.3af-compliant device or from the external
power supply.
