rf dot11a-radio-profile

Name of this instance of the profile. The name must be 1-63 characters.

Range: default

Configure an Air Monitor (AM) scanning profile.

Range: default

Configures Adaptive Radio Management (ARM) feature. See rf arm-profile on page 1.

Range: default

Mute the radio transmission when in AM mode.

Default: Disabled

The assoc-boost parameter increases the client association success rate, especially in a noisy environment. When this parameter is enabled:

• The management frame retransmission retry limit in the radio firmware for both authentication and association response is increased, thereby increasing the management frame retransmission rate.
• If the management frame retransmission retry limit is reached, after a short time delay another round of management frames are scheduled.
• If a client starts an association (by sending a probe or authentication request), AP scanning is rejected for 5 seconds, thereby not missing the client association request.

Range: disabled

Time, in milliseconds, between successive beacon transmissions. The beacon advertises the AP’s presence, identity, and radio characteristics to wireless clients.

Range: 60 (minimum)

Default: 100 milli-seconds

Enabling this setting introduces randomness in the beacon generation so that multiple APs on the same channel do not send beacons at the same time, which causes collisions over the air.

Default: disabled

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.

Range: 1–31 dBm

The cell size reduction feature allows you to manage dense deployments and to increase overall system performance and capacity by shrinking an AP’s receive coverage area, thereby minimizing co-channel interference and optimizing channel reuse. This value should only be changed if the network is experiencing performance issues. The sensitivity range values can be configured from 1 to 20. The default 0 reduction allows the radio to retain its current default Rx sensitivity value.

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) sensitivity level. Failure to match a device’s Tx power level to its Rx sensitivity level can result in a configuration that allows the radio to send messages to a device that it cannot hear.

NOTE: It is recommended that Aruba support engineering is contacted in order to adjust the cell-size-reduction configuration. Manipulating this configuration without guidance from Aruba support may have serious adverse effects on network performance.

Range: 1-20

Default: 0

Channel number for the AP 802.11a/802.11n/802.11ac physical layer. This parameter is only supported on a standalone controller, and is not available in the Mobility Conductor command-line interface.

The available channels depend on the regulatory domain (country). Channel number configuration options for 20 MHz, 40 MHz, and 80 Mhz modes:

• num: Entering a channel number disables 40 MHz mode and activates 20 MHz mode for the entered channel.
• num+: Entering a channel number with a plus (+) sign selects a primary and secondary channel for
  40 MHz and 80 Mhz modes. The number entered becomes the primary channel and the secondary channel is determined by increasing the primary channel number by 4. Example: 157+ represents 157 as the primary channel and 161 as the secondary channel.
• num-: Entering a channel number with a minus (-) sign selects a primary and secondary channel for
  40 MHz and 80 Mhz modes. The number entered becomes the primary channel and the secondary channel is determined by decreasing the primary channel number by 4. Example: 157- represents 157 as the primary channel and 153 as the secondary channel.

NOTE: 20 MHz clients are allowed to associate when a primary and secondary channel are configured; however, the client will only use the primary channel.

Range: Depends on regulatory domain

When you enable the channel reuse feature, it can operate in either of the following three modes; static, dynamic or disable. (This feature is disabled by default.)

• Static mode: 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.
• Dynamic mode: 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.
• Disable mode: This mode does not support the tuning of the CCA Detect Threshold.

Range: enabled, disabled

Default: enabled

RX Sensitivity Tuning Based Channel Reuse Threshold, in - dBm.

If the Rx Sensitivity Tuning Based Channel reuse feature is set to static mode, this parameter manually sets the AP’s Rx sensitivity threshold (in ‑dBm). The AP will filter out and ignore weak signals that are below the channel threshold signal strength.

If the value is set to zero, the feature will automatically determine an appropriate threshold.

Range: Depends on regulatory domain

Name of an existing radio profile from which parameter values are copied.

Channel Switch Announcement (CSA), as defined by IEEE 802.11h, allows an AP to announce that it is switching to a new channel before it begins transmitting on that channel.

Clients must support CSA in order to track the channel change without experiencing disruption.

Default: disabled

Number of CSA announcements that are sent before the AP begins transmitting on the new channel.

Range: 1-16

Default: 4

Specify a number from 0-23 to select the hour during which AirMatch updates are sent to the APs (in 24-hour format). If the managed device to which the AP is associated is in a different time zone than Mobility Conductor, the AirMatch solution will be deployed according to the time zone of the managed device.

NOTE: This parameter is only supported on Mobility Conductor, and is not available in on a standalone controller. If this parameter is set in both the AirMatch profile and the 802.11a radio profile, the setting in the 802.11a radio profile will take precedence.

Range: 0-23

Default: 5

Disables Adaptive Radio Management (ARM) and Wireless IDS functions. These can be disabled if a small increase in packet processing performance is desired. If a radio is configured to operate in Air Monitor mode, then these functions are always enabled irrespective of this option.

CAUTION: Use carefully, since this effectively disables ARM and WIDS.

Default: disabled

Enable advertisement of 802.11d (Country Information) and 802.11h (TPC or Transmit Power Control) capabilities.

Default: disabled

Maximum effective isotropic radiated power (EIRP) from 3 to 33 dBm. You may also specify a special value of 127 dBm for regulatory maximum to disable power adjustments for environments such as outdoor mesh links.

NOTE: This parameter is only supported on Mobility Conductor, and is not available in on a standalone controller.

Range: 1-127

Default: 18

The minimum transmission power level (in dBm) to be assigned to the AP radio(s).

NOTE: This parameter is only supported on Mobility Conductor, and is not available in on a standalone controller.

Range: 1-127

Default: 12

Manually adjust EIRP levels selected by the AirMatch algorithm by specifying a value from -6 to 6 dBm.

NOTE: This parameter is only supported on Mobility Conductor, and is not available in on a standalone controller.

Range: -6 to 6 dBm

Default: 0 dBm

Modify the Energy Detect Threshold (EDT) used by the radio in making transmit decisions. The EDT is a negative value, and the value specified for this parameter (1-12) is the offset from the base value of -59 dBm. For example a value of 1 = -60 dBm, and a value of 10: = -69 dBm.

Specify a value of 0 to use the default EDT for this radio. (This value may vary by AP model)

NOTE: This parameter is only supported on Mobility Conductor, and is not available in on a standalone controller.

Range: 0, 1-12

Default: 0 (disabled)

Starting from ArubaOS 8.7.1.1, the range of energy-detect-threshold parameter has been modified from 0-12 to 12 to -29 dB.

In some dense deployments, it is possible for APs to hear other APs on the same channel. This creates co-channel interference where the traffic of an active client could affect the air traffic of neighboring APs within the same channel. Starting from ArubaOS 8.11.0.0, users are allowed to control frame bursting even if there's only one active client associated to the AP.

Dynamic: Frame bursting will be enabled only when one active client is connected to the AP, and frame bursting will be disabled when there is more than one active client.

OFF: Frame bursting mode is always disabled.

ON: Frame bursting mode is always enabled.

Enables high-efficiency (802.11ax) features on a radio by using the 5 GHz frequency band.

Default: enabled

Enables high-throughput (802.11n) features on a radio using the 5 GHz frequency band.

Default: enabled

Name of high-throughput radio profile to use for configuring high-throughput support on the 5 GHz frequency band. See rf ht-radio-profile on page 1.

Default: default-a

Set a value for 802.11 interference immunity. This parameter sets the interference immunity on the 5 GHz band. When performance drops due to interference from non- 802.11 interferers (such as DECT or Bluetooth devices), the level can be increased for improved performance.

There are 17 levels (0-16) and Table 1, Interference Immunity Levels lists the settings applied for each level.

NOTE: It is recommended not to adjust interference immunity without guidance from Aruba support. Increasing the immunity level in a healthy network may result in severe loss of performance. This should be set to a higher than default level only when there is significant degradation due to non-Wi-Fi interference.

Range: 0-16

Default: 2

Sets the maximum channel bandwidth for APs associated to Mobility Conductor managed devices.

NOTE: This parameter is only supported on Mobility Conductor, and is not available in on a standalone controller.

Range: 20MHz, 40MHz, 80MHz or 160MHz

Default: 80MHz

Sets the minimum channel bandwidth for APs associated to Mobility Conductor managed devices.

NOTE: This parameter is only supported on Mobility Conductor, and is not available in on a standalone controller.

Range: 20MHz, 40MHz, 80MHz

Default: 20MHz

Sets the minimum time between the start of adjacent subframes within an aggregate MPDU. Due to hardware differences, on some platforms this value will be silently restricted to 8us even if a lower value is configured.

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.

The upper limit for this parameter varies, depending on the 20/40 MHz mode for a 5 GHz frequency band radio:

• 20MHz mode: 58km
• 40MHz mode: 27km

Note that if you configure a value above the supported maximum, the maximum supported value will be used instead. Values below 600m will use default settings.

Range: 0-57km (40MHz mode), 0-27km (20MHz mode)

Default: 0 meters

Averaging interval for rate limiting management frames in seconds. Zero disables rate limiting.

NOTE: This parameter only applies to AUTH and ASSOC/RE-ASSOC management frames.

Range: 0-60

Default: 1 second interval

Maximum number of management frames allowed in each throttle interval.

NOTE: This parameter only applies to AUTH and ASSOC/RE-ASSOC management frames.

Range: 0-999999

Default: 20 frames per interval

One of the operating modes for the AP.

Default: ap-mode

Device provides transparent, secure, high-speed data communications between wireless network devices and the wired LAN.

Device behaves as an air monitor to collect statistics, monitor traffic, detect intrusions, enforce security policies, balance traffic load, self-heal coverage gaps, etc.

Device operates as an spectrum monitor, and can send spectrum analysis data to a desktop or laptop client.

Negates any configured parameter.

For internal use only.

Enables or disables radio configuration.

Default: enabled

RTS mode allows users to control RTS frame transmission to the clients.

always-enable: RTS is used for every PPDU/ A-MPDU transmission.

always-disable: RTS is not used for any transmission.

default: The default RTS mode configured in the wireless driver of the AP is used. For 300 Series, 310 Series, 360 Series, 370 Series, AP-387, 530 Series, AP-555, 580 Series, 630 Series, and 635 Series access points, RTS is used for every alternate retried PPDU transmission. For 500H Series, 500 Series, 510 Series, 560 Series, 570 Series, 610 Series access points, RTS is used for all AMPDU transmissions.

Default: default

Enables or disables Traffic Allocation Framework (TAF) in the scheduler profile for debugging purposes.

• fairness: Enables TAF (Default).
• latency: Disables TAF.

NOTE: Aruba Technical Support should be contacted in order to adjust the scheduler-mode configuration. Modifying this configuration without guidance from Aruba Technical Support could cause fairness issues on the network.

SLB Mode allows control over how to balance clients. Select one of the following options

• channel: Channel-based load-balancing balances clients across channels. This is the default load-balancing mode

• radio: Radio-based load-balancing balances clients across APs

Default: channel

Specify how often spectrum load balancing calculations are made (in seconds).

Range: 1-2147483647 seconds

Default: 30 seconds

Enable or disable the smart antenna feature on AP-335 access points.

Range: enabled, disabled

Default: enabled

Define a spectrum load balancing domain to manually create RF neighborhoods.

Use this option to create RF neighborhood information for networks that have disabled Adaptive Radio Management (ARM) scanning and channel assignment.

• If spectrum load balancing is enabled in a 802.11a radio profile but the spectrum load balancing domain is not defined, ArubaOS uses ARM to calculate RF neighborhoods.
• If spectrum load balancing is enabled in a 802.11a radio profile and a spectrum load balancing domain isalso defined, AP radios belonging to the same spectrum load balancing domain will be considered part of the same RF neighborhood for load balancing, and will not recognize RF neighborhoods defined by ARM.

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 Aruba AP on another channel does not have any clients, load balancing will be enabled on that AP.

Default: disabled

Issue this command to turn APs in ap-mode into a hybrid AP. An AP in hybrid AP mode will continue to serve clients as an access point while it scans and analyzes spectrum analysis data for a single radio channel.

For further details on using hybrid APs and spectrum monitors to examine the radio frequency (RF) environment in which the Wi-Fi network is operating,

For a list of APs that can be converted into a spectrum monitor or hybrid AP, refer to

Default: default

Specify the rf spectrum profile used by hybrid APs and spectrum monitors. This profile sets the spectrum band and device ageout times used by a spectrum monitor or hybrid AP radio. For details, see rf spectrum-profile on page 1.

Default: default

Spur Immunity for 5 GHz radio. This parameter fine-tunes the Cyclic Power Threshold (CPT) of a 5 GHz radio. The value specified here is the offset from the base value of 2 dB (for example, setting the CPT value to 1 corresponds to 2 + 1 = 3 dB. Similarly, setting the CPT value to 10 corresponds to 2+10 = 12 dB).

Use this parameter when high channel utilization is observed in the 5 GHz radio of 130 Series access points in a noise-free environment causing client association or throughput issues.

Adjust the CPT value to eliminate the spur impacts. Range definition is as follows:

• 0: default CPT
• 1-19: CPT growth from default (3 dB to 21 dB)
• 20: Setting this parameter to 20 sets the cell-size-reduction value to 1. Cell-size-reduction is the receive coverage area of the AP.

NOTE: Configure this parameter under the supervision of Aruba Technical Support.

NOTE: Setting the spur immunity to a higher value may decrease the AP RF coverage.

NOTE: This parameter is applicable for 130 Series access points only. The controller ignores this parameter if configured for non-130 Series access points.

Range: 0-20 CPT

Default: 0 CPT

Enable or dzisable transmission of frames on the radio.

NOTE: This parameter should only be used for radio test purposes.

Range: enabled, disabled

Default: disabled

Sets the initial transmit power (dBm) on which the AP operates, unless a better choice is available through calibration. This parameter is only supported on a standalone controller, and is not available in the Mobility Conductor command-line interface. This parameter can be set from -51 to 51 in 0.1 dBm increments, or set to the regulatory maximum value of 127 dBm. Transmission power may be further limited by regulatory domain constraints and AP capabilities.

NOTE: Use this parameter to set transmit power levels for APs associated to a stand-alone controller not using ARM.

Range: -51 dBm to 51 dBm

Default: 14 dBm
