About File TransfersTransferring Files
The Network operator can upload and download Operating System code, configuration, and certificate
files to and from a Cisco 2000 Series Wireless LAN Controller and/or Cisco 4100 Series Wireless LAN
Controller using CLI, Web User Interface, or Cisco Wireless Control System (Cisco WCS) commands.
To use CLI commands, refer to Transferring Files To and From a Cisco Wireless LAN Controller.
To use the Web User Interface, go to Using the Web User Interface.
To use Cisco WCS commands, continue with Using the Cisco Wireless Control System.
About Power Over EthernetPower Over Ethernet
Cisco 1000 Series lightweight access points support 802.3af-compatible Power over Ethernet (PoE),
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 IEEE 802.11a/b/g Lightweight
Access Points, Cisco 1030 IEEE 802.11a/b/g Remote Edge 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 Cisco 1000 Series light-
weight access point to a PoE power hub or to a Cisco Single-Line PoE Injector, described in Cisco 1000
Series Lightweight Access Point Models. When the PoE equipment determines that the Cisco 1000
Series lightweight access point is PoE-enabled, it sends 48 VDC over the unused pairs in the Ethernet
cable to power the access point.
The PoE cable length is limited by the 100BASE-T or 10BASE-T specification to 100 m or 200 m,
respectively.
Pico Cell FunctionalityPico Cell Functionality
Pico Cell functionality includes optimization of the OS to support this functionality as follows:
The Cisco WCS Pico Cell Mode parameter reconfigures OS parameters, allowing OS to function
efficiently in pico cell deployments. Note that when the operator is deploying a pico cell network
the OS must also have more memory allocated (512 to 2048 MB) using the config database
size 2048 CLI command.
Client mobility between multiple mobility domains when such exist.
Addition of a WPA2 VFF extension to eliminate the need to re-key after every association. This
allows the re-use of existing PTK and GTK.
With WPA2 PMK caching and VFF, the PMK cache is transferred as part of context transfer prior
to the authentication phase. This allows expedited handoffs to work for both intra- and
inter-Cisco Wireless LAN Controller roaming events.
A beacon/probe response that allows a Cisco 1000 Series lightweight access point to indicate
which switch it is attached to so that reauthorization events will only occur when needed,
minimizing inter-switch handoffs and thus reducing CPU usage.
Ability to change AP sensitivity for pico cells.
Note: Cisco 1000 Series lightweight access points can receive power from any other
network device conforming to the IEEE 802.3af standard.
Note: Each Cisco 1000 Series lightweight access point can alternatively receive
power from one Cisco 1000 Series Lightweight Access Point External Power Supply.
