Enable broadcast service set identifier (SSID) per WLANWith broadcast SSID
enabled, the WLAN/SSID information is sent in the beacons. This also helps clients
that perform passive scanning (those that do not transmit probe request) as well as
clients configured without an SSID to associate with the controller through this
WLAN.
♦
Disable Aironet extensions (if enabled) per WLANCisco−proprietary Aironet
extensions detect the capabilities of Cisco Aironet client devices and support features
that require specific interaction between the Cisco Access Point (AP) (hence the
controller) and associated client devices. Non−Cisco clients do not always support the
Aironet extensions. With Aironet Extensions disabled on a particular WLAN,
interoperability with the non−Cisco devices can be improved. Therefore, a controller
can interoperate with a non−Cisco client device that associates through this WLAN.

Disable client exclusions per WLAN.♦
Disable Management Frame Protection (MFP) signature generation (if enabled) per
WLANRefer to Infrastructure Management Frame Protection (MFP) with WLC and
LAP Configuration Example for more information on MFP.
♦
Disable aggressive load balancing globally on the controller.♦
From the controller GUI, disable client exclusion policies under Security > wireless
protection policies.
♦
From the controller GUI, set AP authentication/MFP to off under Security > wireless
protection policies.

Disable short preambleThe radio preamble, which is sometimes called a header, is a
section of data at the head of a packet that contains information that wireless devices
need when sending and receiving packets. You can set the radio preambles to long or
short.
ShortA short preamble improves throughput performance and is enabled by
default. Cisco Aironet Wireless LAN Client Adapters support short
preambles. Early models of Cisco Aironet's Wireless LAN Adapter (PC4800
and PC4800A) require long preambles. However, some wireless devices,
such as SpectraLink NetLink phones, require long preambles. In such cases,
unchecking short preamble enables long preamble to achieve interoperability
with Spectralink Netlink phones. Refer to Using the GUI to Enable Long
Preambles for information on how to disable short preamble.
◊
LongA long preamble ensures compatibility between the access point and
all early models of Cisco Aironet Wireless LAN Adapters (PC4800 and
PC4800A). If these client devices do not associate to your access points, you
should use short preambles.

Q. Can a Wireless LAN Controller (WLC) be managed by CiscoWorks,
which is used to manage routers and switches?
A. No, CiscoWorks cannot manage a WLC. A Wireless Control System (WCS) is needed to
manage the WLC.
Q. What is the maximum number of rogue access points (APs) per
controller?
A. The maximum number of rogue APs is 100 per 2006 Wireless LAN Controller, and 500
for all other platforms.
