Description

This command configures AP radio settings for the 2.4 GHz frequency band, including the Adaptive Radio Management (ARM) profile and the high-throughput (802.11n) radio profile. Channels must be valid for the country configured in the AP regulatory domain profile (see ap regulatory-domain-profile on page 1).To view the supported channels, use the show ap allowed-channels command.

APs initially start up with default ack-timeout, cts-timeout and slot-time values. When you modify the maximum-distance parameter in an rf dot11a radio profile or rf dot11g radio profile, new ack-timeout, cts-timeout and slot-time values may be derived, but those values are never less then the default values for an indoor AP.

Mesh radios on outdoor APs have additional constraints, as mesh links may need to span long distances. For mesh radios on outdoor APs, the effect of the default maximum-distance parameter on the ack-timeout, cts-timeout and slot-time values depends on whether the APs are configured as mesh portals or mesh points. This is because mesh portals use a default maximum-distance value of 16,050 meters, and mesh points use, by default, the maximum possible maximum-distance value.

The maximum-distance value should be set correctly to span the largest link distance in the mesh network so that when a mesh point gets the configuration from the network it will apply the correct ack-timeout, cts-timeout and slot-time values. The values derived from the maximum-distance setting depend on the band and whether 20Mhz/40MHz mode of operation is in use.

Parameter

Description

<profile>

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

Default: default

airmatch-mode-aware

If enabled, AirMatch turns off radios in high density deployment.

Default: Disabled

am-scan-profile <profile-name>

Configure an Air Monitor (AM) scanning profile.

am-tx-mute

Mute the radio transmission when in AM mode.

Default: D isabled

arm-profile

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

Default: default

assoc-boost

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.

Default: disabled

beacon-period

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 milliseconds

beacon-regulate

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

cap-reg-eirp <cap-reg-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.

Range: 1–31 dBm

cell-size-reduction
<cell-size-reduction>

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

Channel number for the AP 802.11g/802.11n.802.11ac physical layer. The available channels depend on the regulatory domain (country). This parameter is only supported on a standalone controller, and is not available in the Mobility Conductor command-line interface.

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

clone

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

csa

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

csa-count

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

Range: 1-16

Default: 4

channel-reuse

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

channel-reuse-threshold

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

deploy-hour <0-23>

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 802.11g radio profile, the setting in the 802.11g radio profile will take precedence.

Range: 0-23

Default: 5

disable-arm-wids-functions

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

dot11b-protection

Enable or disable protection for 802.11b clients. This parameter is enabled by default. Disabling this feature may improve performance if there are no 802.11b clients on the WLAN.

WARNING: Disabling protection violates the 802.11 standard and may cause interoperability issues. If this feature is disabled on a WLAN with 802.11b clients, the 802.11b clients will not detect an 802.11g client talking and can potentially transmit at the same time, thus garbling both frames.

Default: enabled

dot11h

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

Default: disabled

eirp-max

Maximum effective isotropic radiated power (EIRP) from 3 to 33 dBm in 3 dBm increments. 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: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33 or 127

Default: 9

eirp-min

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: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33 or 127

Default: 6

eirp-offset

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

energy-detect-threshold

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)

Range: 0, 1-12

Default: 0 (disabled)

frame-bursting-mode

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 AOS 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.

high-efficiency-enable <radio>

Enables high-efficiency (802.11ax) features on a radio using the 2.4 GHz frequency band.

Default: enabled

high-throughput-enable

Enables high-throughput (802.11n) features on a radio using the 2.4 GHz frequency band.

Default: enabled

ht-radio-profile

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

interference-immunity

 

Set a value for 802.11 interference immunity. This parameter sets the interference immunity on the 2.4 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 HPE Aruba Networking 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

iot-coex-enable

Enables WLAN co-existence feature with IoT and avoids simultaneous transmissions.

Default: enabled

max-channel-bandwidth

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: 20MHz

NOTE: 80Mhz and 160MHz are not valid options for the 802.11g radio profile.

min-channel-bandwidth

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

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.

The upper limit for this parameter varies, depending on the 20/40 MHz mode for a 2.4GHz frequency band radio:

  • 20MHz mode: 54km
  • 40MHz mode: 24km

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: 0-24km (40MHz mode), 0-54km (20MHz mode)

Default: 0 meters

mgmt-frame-throttle-
interval

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

mgmt-frame-throttle-limit

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

mode

One of the operating modes for the AP.

Default: ap-mode

ap-mode

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

am-mode

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

spectrum-mode

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

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

no

Negates any configured parameter.

rts-mode

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

radio-enable

Enables or disables radio configuration.

Default: enabled

scheduler-mode <fairness|latency>

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 channel|radio

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

slb-threshold

If the spectrum load balancing feature is enabled, this parameter controls the percentage difference between number of clients on a channel that triggers load balancing. The default value is 20%, meaning that spectrum load balancing is activated when there are 20% more clients on one channel than on another channel used by the AP radio.

Range: 1-100%

Default: 20%

slb-update-interval <secs>

Specify how often spectrum load balancing calculations are made (in seconds). The default value is 30 seconds.

Range: 1-2147483647 seconds

Default: 30 seconds

smart-antenna

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

Range: enabled, disabled

Default: enabled

spectrum-load-bal-domain

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 802.11g radio profile but the spectrum load balancing domain is not defined, AOS uses ARM to calculate RF neighborhoods.
  • If spectrum load balancing is enabled in a 802.11g 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.

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

Default: disabled

spectrum-monitoring

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

spectrum-profile <profile>

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

transmit

Enable or disable transmission of frames on the radio.

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

Range: enabled, disabled

Default: disabled

tx-power

Sets the initial transmit power (dBm) on which the AP operates, unless a better choice is available through calibration.

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: This parameter is only supported on a standalone controller, and is not available in the Mobility Conductor command-line interface.

Range: -51 dBm to 51 dBm

Default: 14 dBm

very-high-throughput-rates-enable

This feature enables Very High Throughput (VHT) rates on the 2.4 GHz band, providing 256-QAM modulation and encoding that allows for 600 Mbit/sec performance over 802.11n networks. Maximum data rates are increased on the 2.4 GHz band through the addition of VHT Modulation and Coding Scheme (MCS) values 8 and 9, which support the highly efficient modulation rates in 256-QAM. Starting with AOS 6.4.2.0, VHT is supported on 220 Series access points on both 20 and 40 MHz channels.

Using the controller’s CLI or WebUI, VHT MCS values 0-9 are enabled, overriding the existing high-throughput (HT) MCS values 0-7, which have a lower maximum data rate. However, this feature should be disabled if individual rate selection is required.

Default: disabled

  • Adaptive Noise Immunity: Adjust noise and spur immunity levels based on PHY errors.
  • Preemption mode: The radio stops current reception and restarts the receiver when a new signal which is above the threshold of the current signal is found. This allows the radio to switch signals when it locks onto interference or weaker 802.11 signal, when a valid 802.11 signal with a higher signal strength is detected.
  • Low Noise Amplifier: Enables radio saturation at lower signal levels resulting in better performance in the presence of interference. Disabling LNA avoids radio saturation at lower signal levels. However, it may reduce range and throughput.
  • Interference Sensitivity Reduction: Reduces the sensitivity to both Wi-Fi and non Wi-Fi interference signals. This makes the radio deaf to signals in which the SNR is below the threshold.
  • Force Noise Floor (for 2.4 GHz radio only): Forces the radio to use the configured value as the absolute noise floor value. This makes the radio ignore signals of weaker amplitude.
