Spectrum Load balancing mode SLB Mode allows control over how to balance clients. Channel-based load-balancing
balances clients across channels. Radio-based load-balancing distributes clients across
radios on the same band, independent of channels.
Spectrum Load balancing mode
update interval
This parameter specifies how often spectrum load balancing calculations are made (in
seconds). The default value is 30 seconds.
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.
RX Sensitivity Tuning Based
Channel Reuse
Shows if the channel reuse feature’s current operating mode, static, dynamic or disable.
z Static: This mode of operation is a coverage-based adaptation of the Clear Channel
Assessment (CCA) thresholds. In the static mode of operation, the CCA is adjusted
according to the configured transmission power level on the AP, so as the AP transmit
power decreases as the CCA threshold increases, and vice versa.
z Dynamic: In this mode, the Clear Channel Assessment (CCA) thresholds are based on
channel loads, and take into account the location of the associated clients. When you
set the Channel Reuse This feature is automatically enabled when the wireless
medium around the AP is busy greater than half the time. When this mode is enabled,
the CCA threshold adjusts to accommodate transmissions between the AP its most
distant associated client.
z Disable: This mode does not support the tuning of the CCA Detect Threshold.
RX Sensitivity Threshold If the Rx Sensitivity Tuning Based Channel reuse feature is set to static mode, this
parameter manually sets the AP’s Rx sensitivity threshold (-dBm). The AP will filter out and
ignore weak signals that are below the channel threshold signal strength. For example, if
the RX sensitivity threshold was set to -65 dBm, the AP would ignore signals with a
strength from -1 dBM to -64 dBm. If the value is set to zero, the feature will automatically
determine an appropriate threshold.
Enable CSA Shows if Channel Switch Announcements (CSAs) are enabled or disabled. CSAs, as
defined by IEEE 802.11h, enable an AP to announce that it is switching to a new channel
before it begins transmitting on that channel. This allows clients that support CSA to
transition to the new channel with minimal downtime.
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.
Management Frame Throttle
Interval
Averaging interval for rate limiting mgmt frames from this radio, in seconds. A management
frame throttle interval of 0 seconds disables rate limiting.
Management Frame Throttle Limit Maximum number of management frames that can come in from this radio in each throttle
interval.
ARM/WIDS Override If enabled, 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 override functions are always enabled,
regardless of whether or not this check box is selected.
Adaptive Radio Management
(ARM) Profile
Name of an Adaptive Radio Management profile associated with this 802.11a profile.
Maximum Distance Maximum distance between a client and an AP or between a mesh point and a mesh
portal, in meters. This value is used to derive ACK and CTS timeout times. A value of 0
specifies default settings for this parameter, where timeouts are only modified for outdoor
mesh radios which use a distance of 16km.
