Parameter Description
Customize Valid
Channels
Select this check box to customize valid channels for 2.4 GHz and 5 GHz. By
default, the W-IAP uses valid channels as defined by the Country Code
(regulatory domain). On selecting the Customize Valid Channels check box, a
list of valid channels for both 2.4 GHz and 5 GHz are displayed. The valid
channel customization feature is disabled by default.
Minimum Transmit
Power
Specify the minimum transmission power. The value specified for Minimum
Transmit Power indicates the minimum Effective Isotropic Radiated Power
(EIRP) that can range from 3 dBm to 33 dBm in 3 dBm increments. If the
minimum transmission EIRP setting configured on a W-IAP is not supported by
the W-IAP model, this value is reduced to the highest supported power setting.
The default value for minimum transmit power is 18 dBm.
Maximum Transmit
Power
Specify the maximum transmission power. The value specified for Maximum
Transmit Power indicates the maximum Effective Isotropic Radiated Power
(EIRP) that can range from 3 dBm to 33 dBm in 3 dBm increments. If the
maximum transmission EIRP configured on a W-IAP is not supported by the W-
IAP model, the value is reduced to the highest supported power setting. The
default value for maximum transmit power is 127 dBm.
Client aware
When Enabled, ARM does not change channels for the W-IAPs with active
clients, except for high-priority events such as RADAR or excessive noise. This
feature must be enabled in most deployments for a stable WLAN. If the Client
Aware mode is Disabled, the W-IAP may change to a more optimal channel,
that may disrupt the current client traffic for a while. The Client aware option is
Enabled by default.
NOTE: When Client aware is disabled, channels can be changed even when the
clients are active on a BSSID.
Scanning
Select Enabled so that the W-IAP dynamically scans all 802.11 channels within
its 802.11 regulatory domain at regular intervals and reports to the W-IAP. This
scanning report includes WLAN coverage, interference, and intrusion detection
data.
NOTE: For client match configuration, ensure that scanning is enabled.
Wide Channel
Bands
Select a band to allow the W-IAPs to be placed in 40 MHz (wide band) channels.
The Wide Channel Bands allows administrators to configure 40 MHz channels
in the 2.4 GHz and 5 GHz bands. 40 MHz channels are two 20 MHz adjacent
channels that are bonded together. A 40 MHz channel effectively doubles the
frequency bandwidth available for data transmission.
80 MHz Support Enables or disables the use of 80 MHz channels on W-IAPs. This feature allows
ARM to assign 80 MHz channels on W-IAPs with 5 GHz radios, which support a
very high throughput. This setting is enabled by default.
NOTE: Only the W-IAPs that support 802.11ac can be configured with 80 MHz
channels.
