Parameter Description
CSA Count Number of channel switch announcements that must be sent prior to switching to a
new channel. The default CSA count is 4 announcements.
Advertise 802.11d
and 802.11h
Capabilities
Enable the radio to advertise its 802.11d (Country Information) and 802.11h
(Transmit Power Control) capabilities. This option is disabled by default.
Spectrum Load
Balancing
The Spectrum Load Balancing feature helps optimize network resources by
balancing clients across channels, regardless of whether the AP or the controller is
responding to the wireless clients' probe requests.
If enabled, the controller compares whether or not an AP has more clients than its
neighboring APs on other channels. If an AP’s client load is at or over a
predetermined threshold as compared to its immediate neighbors, or if a
neighboring Dell AP on another channel does not have any clients, load balancing
will be enabled on that AP. This feature is disabled by default. For details, see
Spectrum Load Balancing on page 529.
Beacon Period Beacon Period for the AP in msec. The minimum value is 60 msec, and the default
value is 100 msec.
Beacon Regulate Enable this setting to introduce randomness in the beacon generation so that
multiple APs on the same channel do not send beacons at the same time.
Advertised
Regulatory Max
EIRP
Work around a known issue on Cisco 7921G telephones by specifying a cap for a
radio’s maximum equivalent isotropic radiated power (EIRP). When you enable this
parameter, even if the regulatory approved maximum for a given channel is higher
than this EIRP cap, the AP radio using this profile will advertise only this capped
maximum EIRP in its radio beacons.
The supported range is 1-31dBm.
ARM/WIDS
Override
If selected, this option disables Adaptive Radio Management (ARM) and Wireless
IDS functions and slightly increases packet processing performance. If a radio is
configured to operate in Air Monitor mode, then the ARM/WIDS functions are
always enabled, regardless of whether or not this check box is selected.
Reduce Cell Size (Rx
Sensitivity)
The cell size reduction feature allows you manage dense deployments and to
increase overall system performance and capacity by shrinking an AP’s receive cov-
erage area, thereby minimizing co-channel interference and optimizing channel
reuse. This value should only be changed if the network is experiencing per-
formance issues. The possible range of values for this feature is 0-55 dB. The
default 0 dB reduction allows the radio to retain its current default Rx sensitivity
value.
Values from 1 dB - 55 dB reduce the power level that the radio can hear by that
amount. If you configure this feature to use a non-default value, you must also
reduce the radio’s transmission (Tx) power to match its new received (Rx) power
level. Failure to match a device’s Tx power level to its Rx power level can result in a
configuration that allows the radio to send messages to a device that it cannot hear.
