• PMKID Caching - Allows the device to skip 802.1x authentication during roaming if it had previously
connected to that AP with a full 802.1x authentication. Default: disabled. Note: disable OKC when enabling
PMKID Caching.
• Opportunistic Key Caching - Use this feature to skip 802.1x authentication during roaming. The device
will go for full 802.1x authentication for the first time it connects to the network. For subsequent roaming,
the device skips 802.1x authentication. Default: enabled.
• Cisco Centralized Key Management - Allows the device to skip 802.1x and key-handshake phases during
roaming. This feature is available only when the device is connected to a Cisco infrastructure that supports
Cisco Centralized Key Management (CCKM). Default: enabled.
• Fast Transition - Fast Transition (FT) is the fast roaming standard, 802.11r. With this feature, the device
can skip 802.1x and key-handshake phases during roam. Default: enabled.
• Fast Transition Resource Information Container - Allows the device to request TSPEC as part of
reassociation frame exchange. This helps to avoid sending a separate resource request after roaming is
completed. Default: enbled.
• Power Save - The device can be configured to work in different power save modes:
i. Active - Keeps the WLAN radio always in active mode (i.e. power save mode disabled).
ii. Power save using WMM-PS - This is the default power save mode. Device uses WMM-PS power
save method if the AP is configured to use this. If the AP is not supporting WMM-PS, the device will
use PS-Poll power save method.
iii. Power save using PS-Poll - In this method, the device will use PS-Poll frames to retrieve buffered
frames from the AP.
iv. Null Data Power Save - In Null Data Power Save (NDP), the device will stay awake for 100 ms after
the last frame is sent or received. The device will send a Null Data packet with power management
bit cleared to retrieve buffered frames from the AP.
• 802.11k - Using 802.11k, the device can discover neighbor APs and adds support for different types of
radio resource measurements. Default: enabled.
• Band Preference - The device can be configured to prefer one band over another. Default:
disabled.Subnet Roaming - When the device roams between different sub networks, if it detects that it is
roaming to a different subnet, the device will request a fresh IP address. Default: disabled.
Bluetooth
Bluetooth devices can communicate without wires, using frequency-hopping spread spectrum (FHSS) radio
frequency (RF) to transmit and receive data in the 2.4 GHz Industry Scientific and Medical (ISM) band
(802.15.1). Bluetooth wireless technology is specifically designed for short-range (10 m (32.8 ft))
communication and low power consumption.
Devices with Bluetooth capabilities can exchange information (for example, files, appointments, and tasks)
with other Bluetooth enabled devices such as printers, access points, and other mobile devices.
The device supports Bluetooth Low Energy. Bluetooth Low Energy is targeted at applications in the healthcare,
fitness, security, and home entertainment industries. It provides reduced power consumption and cost while
maintaining standard Bluetooth range.
Adaptive Frequency Hopping
Adaptive Frequency Hopping (AFH) is a method of avoiding fixed frequency interferers, and can be used with
Bluetooth voice. All devices in the piconet (Bluetooth network) must be AFH-capable in order for AFH to work.
There is no AFH when connecting and discovering devices. Avoid making Bluetooth connections and
discoveries during critical 802.11b communications. AFH for Bluetooth consists of four main sections:
