Usage Guidelines

Usage Scenario

After an air scan profile is created using the air-scan-profile command and bound to a radio profile, and scanning functions are enabled, such as radio calibration, smart roaming, spectrum analysis, WLAN location, and WIDS, the AP periodically scans surrounding radio signals and reports the collected information to an AC or a server. The information is used for radio calibration, smart roaming spectrum analysis, WLAN location, or WIDS data analysis.

Follow-up Procedure

Run the air-scan-profile (radio profile view) command to bind the air scan profile to a 2G radio profile or 5G radio profile so that the air scan profile can take effect.

Example

# Create the air scan profile air-scan01.

Default Level

2: Configuration level

Usage Guidelines

You can run the undo band-steer disable command to configure the band steering function. If an AP and STAs connected to the AP can work at both 2.4 and 5 GHz radios, the band steering function allows radios of the AP to load balance traffic. This helps minimize interference between STAs and improve user experience.

When a STA requests to connect to an AP radio, the AP enabled with band steering will collect statistics about access users on each radio.
  1. If the number of access users on the AP does not exceed start-threshold specified using the band-steer balance start-threshold command, the STA can preferentially associate with the 5 GHz radio.
  2. If the number of access users on the AP exceeds start-threshold, the AP determines the frequency band to which the STA connects based on radio load difference computed according to the formula: (Number of access users on the 5 GHz radio – Number of access users on the 2.4 GHz radio)/Number of access users on the 5 GHz radio * 100%.

For example, if a STA requests to associate with the AP at the 2.4 GHz radio but the number of access users on the AP has exceeded start-threshold, the AP implements load balancing between the 2.4 GHz and 5 GHz radios according to their load difference. If the value obtained based on the formula (Number of access users on the 5 GHz radio – Number of access users on the 2.4 GHz radio)/Number of access users on the 5 GHz radio * 100% is greater than gap-threshold, the AP preferentially associates with the STA on the 2.4 GHz radio; otherwise, the AP preferentially associates with the STA on the 5 GHz radio.

You can run the undo band-steer disable command to configure the band steering function. If an AP and STAs connected to the AP support both radios, the band steering function allows radios of the AP to load balance traffic. This helps minimize interference between STAs and improve user experience.

When a STA requests to connect to an AP radio, the AP enabled with band steering will collect statistics about access users on each radio.

Views

RRM profile view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

After the band steering function is enabled on an AP, the AP records frequency band information of terminals so that the terminals can preferentially access the supported and lightly loaded frequency band.

Users may change terminals' configurations, which causes the supported frequency band of terminals to change. Therefore, the AP needs to update frequency band information of terminals in a timely manner. If the AP keeps receiving Probe frames of a terminal from a specific frequency band, and the number of receiving times exceeds a certain threshold, the AP updates the frequency band information of the terminal and considers that the terminal supports only the frequency band.

For example, the supported frequency bands of a terminal are 2.4 and 5 GHz frequency bands on an AP. If the AP only receives Probe frames of the terminal from the 2.4 GHz frequency band, and the number of times that the AP consecutively receives Probe frames from the 2.4 GHz frequency band exceeds the specified threshold, the AP considers that users change the terminal configuration and the terminal supports only the 2.4 GHz frequency band.

Precautions

If you set the aging condition to a large number of times that an AP consecutively receives Probe frames of a terminal from the same frequency band, the AP detects terminal band change more slowly. A smaller number indicates quicker response. Set the aging condition according to the difference in the number of Probe frames sent from the two frequency bands.

Example

# Configure the supported band information of the terminal huawei to age out when the number of times that an AP consecutively receives Probe frames from a frequency band exceeds 80.

If a STA requests to associate with an AP from the 2.4 GHz frequency band but the AP steers the STA to the 5 GHz frequency band according to the band steering algorithm, the AP will reject the association. However, after the number of rejections exceeds the maximum value specified by the band-steer deny-threshold command, the AP allows the STA to associate from the 2.4 GHz frequency band.

2: Configuration level

Usage Guidelines

Usage Scenario

Compared with the 2.4 GHz frequency band, the 5 GHz frequency band has less interference and more available channels, and provides higher access capability.

Most STAs support both 5 GHz and 2.4 GHz frequency bands and usually associate with the 2.4 GHz radio by default when connecting to the Internet. To connect the STAs to the 5 GHz radio, you must manually select the 5 GHz radio. The band steering function frees you from the manual selection.

After you enable band steering for a specific SSID on the AC, the AP preferentially associates the terminals connected to the SSID with the 5 GHz frequency band. After the 5 GHz frequency band is fully loaded, the AP steers the terminals to the 2.4 GHz frequency band.

Configuration Impact

After the band steering function is enabled, it takes a long time for dual-band terminals to associate or roam. You are advised to disable band steering for delay-sensitive services.

Precautions

If both radios of an AP use the same VAP profile, the band steering function takes effect on both radios as long as the function is enabled for an SSID on one radio of the AP. For example, if band steering is enabled for the SSID huawei on the 2.4 GHz radio but not on the 5 GHz radio, the AP preferentially steers terminals associated with the SSID to the 5 GHz radio.

Single-radio devices do not support the band steering function.

The AP2010DN does not support the band steering function.

Usage Guidelines

Two channel selection modes are available:
  • Automatic mode (enabling automatic channel selection): An AP automatically selects a proper channel based on the WLAN radio environment, removing the need to specify channels manually.
  • Fixed mode (disabling automatic channel selection): Channels must be manually specified.

The automatic mode (automatic channel selection) is recommended because you do not need to specify a channel for each radio. The fixed mode provides users with an alternative way when they want to specify channels by themselves or to avoid frequent channel adjustment (this may cause intermittent service interruption).

If an AP needs radio calibration, automatic channel selection must be enabled.

NOTE:

When automatic channel selection is enabled, the manually configured channels do not take effect to ensure that the radio works in the optimal channel environment.

If the MAC layer of a radio does not receive any ACK packet after sending a packet at the lowest rate, it considers that an error occurs.

The BER threshold determines whether the radio environment is normal. When the BER of a radio reaches the threshold, the system considers that the radio environment deteriorates. When this occurs, the system may start radio calibration or take measures to avoid signal interference.

Usage Guidelines

Usage Scenario

After radio calibration is enabled, an AP uses the Transmit Power Control (TPC) algorithm to calculates the transmit power to be adjusted based on detected neighbor information. If the transmit power to be adjusted calculated using the TPC algorithm is to large, signal interference between APs may occur. You can run the calibrate max-tx-power command to set the maximum transmit power that can be adjusted through TPC.

Precautions

The maximum radio calibration power must be larger or equal to the minimum radio calibration power. You can run the calibrate min-tx-power command to set the minimum calibration power.

You can adjust the maximum and minimum calibration powers using the calibrate max-tx-power and calibrate min-tx-power commands. The valid power after radio calibration is between the two values. If the values are set improperly, the maximum and minimum calibration power settings may fail to take effect.
  • If the maximum calibration power is smaller than the minimum transmit power of an AP, the minimum transmit power takes effect. For example, if the minimum transmit power of an AP on the 2.4 GHz band is 9 dBm and the maximum calibration power is set to 8 dBm, the transmit power on the 2.4 GHz band is 9 dBm after radio calibration.
  • If the minimum calibration power is smaller than the maximum transmit power of an AP, the maximum transmit power takes effect. For example, if the maximum transmit power on the 2.4 GHz band is 21 dBm and the minimum calibration power is set to 25 dBm, the transmit power on the 2.4 GHz band is 21 dBm after radio calibration.

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

The noise floor indicates the noise strength in the current environment. A high noise floor value will make noise drown out valid data, affecting user services.

The noise floor threshold for triggering radio calibration can be used to determine whether the environment noise is normal. When detecting a noise floor value higher than the threshold, an AP reports a high noise floor message to the AC. The AC then performs radio calibration to avoid channels with high noise floor values to improve user experience.

Example

# Set the noise floor threshold for triggering radio calibration to -60 dBm.

Usage Guidelines

Usage Scenario

Radio calibration policies are classified into:
NOTE:

The noise floor, rogue AP and non-Wi-Fi policies take effect only in automatic radio calibration mode.

  • Rogue AP policy: When rogue APs (out of control by an AC) exist on a network, set the radio calibration policy to rogue-ap. The device then immediately takes actions to avoid interference. This policy may lead to frequency channel switchovers. You are advised to use this policy under the instruction of technical support personnel.
  • Load policy: When this radio calibration policy is used, the AP traffic load difference is considered for channel allocation. The device allocates channels with less interference to APs with heavier loads. The AP load changes with times. You are advised to use this policy under the instruction of technical support personnel.
  • Non-Wi-Fi policy: When non-Wi-Fi interference occurs on a network, the device immediately takes actions to avoid interference.
  • Noise floor policy: When the noise floor of APs is high due to special external interference, service experience may deteriorate. With this radio calibration policy, the device takes actions to avoid interference. When detecting that the noise floor of the current channel exceeds the threshold for three consecutive times, an AP notifies the AC of the high noise floor. The AC then allocates another channel to the AP and does not allocate the current channel to the AP in 30 minutes.

Radio calibration triggers channel changes. Some STAs may go offline and then go online again. If these STAs exist on the network, to ensure service experience, you are advised to perform radio calibration when no service is running and disable policies that frequently trigger radio calibration. You can run the display channel switch-record calibrate command to check policies that frequently trigger radio calibration.

The three radio calibration policies can be used together. You can run the command multiple times to configure different radio calibration policies according to service requirements.

Prerequisites

The noise floor threshold for triggering radio calibration has been specified using the calibrate noise-floor-threshold threshold command.

Default Level

2: Configuration level

Usage Guidelines

The CCA mechanism enables a WLAN chip to determine whether the channel is idle before transmitting signals to the air interface. If so, the chip transmits signals. If not, the chip waits until the channel is idle.

The CCA threshold is used by a WLAN chip to determine whether the channel is idle. If the noise on the channel exceeds the threshold, the chip considers the channel busy. Otherwise, the chip considers the channel idle.

When deploying a WLAN, set a proper CCA threshold to reduce signal interference and improve the channel reuse rate.
  • If APs densely are deployed, a high CCA threshold is recommended to narrow down the coverage and skip remote weak signals.
  • If APs are sparsely deployed, a low CCA threshold is recommended to maximize the effective coverage of signals.

# Set the CCA threshold for a 2G radio to -70 dBm.

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

The 5 GHz frequency band has richer spectrum resources. In addition to 20 MHz channels, APs working on the 5 GHz frequency band support 40 MHz and 80 MHz channels. Larger-bandwidth channels mean higher transmission rates. However, at least three channels are required in radio calibration to achieve the optimal calibration effect. When configuring the calibration bandwidth, ensure that enough calibration channels are available for use.

You can use the dca-channel bandwidth command to configure the calibration bandwidth and the dca-channel channel-set command to configure calibration channels as prompted.

Configuration Impact

When the calibration bandwidth is changed, the device recalculates the calibration channels.

Precautions

Only the AP2030DN, AP1050DN-S, AP8050DN, AP8050DN-S, AP8150DN, AP4050DN, AP4050DN-S, AP4051DN, AP4151DN, AP2050DN, AP2050DN-E, AP4030DN, AP4130DN, AP5030DN, AP4030TN, AP4050DN-E, AP4050DN-HD, AP6050DN, AP6150DN, AP7050DN-E, AP5130DN, AP7030DE, AP9131DN, AP9132DN, AD9430DN-24 central AP (including the mapping RUs), AD9430DN-12 central AP (including the mapping RUs), AD9431DN-24X central AP (including the mapping RUs), AP4051TN, AP6052DN, AP7052DN, AP7152DN, AP7052DE, AP8050TN-HD, AP8082DN, AP8182DN, AP9330DN, AP8030DN, AP8130DN-W, and AP8130DN support 80 MHz calibration bandwidth.

When configuring 40 MHz or 80 MHz calibration bandwidth, check whether channels of the corresponding bandwidth exist under the country code.

Example

# Set the calibration bandwidth to 40 MHz.

dca-channel channel-set

Function

The dca-channel channel-set command configures a calibration channel set.

The undo dca-channel channel-set command restores the default calibration channel set.

By default, a calibration channel set contains channels 1, 6, and 11 on the 2.4G radio and contains all channels supported by the corresponding country code on the 5G radio. If the country code is China, the calibration channel set does not contain channels 36 to 64. When configuring the calibration channels, users can specify channels as prompted.

Format

dca-channel { 2.4g | 5g } channel-set channel-value

undo dca-channel { 2.4g | 5g } channel-set

Parameters

Parameter Description Value
2.4g | 5g
Specifies the frequency band on which radio calibration is performed.
  • 2.4g: Radios work on the 2.4 GHz frequency band.
  • 5g: Radios work on the 5 GHz frequency band.

channel-set channel-value

Specifies a calibration channel set.

The value is a character string. You can select calibration channels as prompted. If you select multiple channels, use commas (,) to separate channel names.

Default Level

2: Configuration level

Usage Guidelines

The 5 GHz frequency band has richer spectrum resources. In addition to 20 MHz channels, APs working on the 5 GHz frequency band support 40 MHz and 80 MHz channels. Larger-bandwidth channels mean higher transmission rates. However, at least three channels are required in radio calibration to achieve the optimal calibration effect. When configuring the calibration bandwidth, ensure that enough calibration channels are available for use.

You can run this command to specify a calibration channel set for an AP. The AP selects channels from the channel set to calibrate. This reduces the burden on the AP.

NOTE:

To ensure a good calibration effect, you are advised to configure at least three calibration channels.

To prevent signal interference, ensure that adjacent APs work in non-overlapping channels. The 2.4 GHz frequency band has overlapping channels. When configuring calibration channels, you are advised to configure a non-overlapping calibration channel set containing channels 1, 6, and 11 or containing channels 1, 5, 9, and 13.

To specify a 40 MHz calibration channel, you need to specify two consecutive 20 MHz channels. To specify an 80 MHz calibration channel, you need to specify four consecutive 20 MHz channels. The combinations of 20 MHz channels making up the 40 MHz and 80 MHz channels are fixed.

You can also use the dca-channel bandwidth command to configure the calibration bandwidth and the dca-channel channel-set command to configure calibration channels as prompted.

If no calibration channel set is configured, the device probes channels based on the calibration channels corresponding to the country code.

NOTE:

When configuring a calibration channel set, avoid using radar channels.

The channels you configure must be supported by the terminals; otherwise, the terminals cannot discover wireless signals. For example, when the country code is set to China, 5 GHz channels 36, 40, 44, 48, 52, 56, 60, and 64 can be configured. However, most terminals do not support these channels currently. If these channels are configured, the terminals cannot discover wireless signals. In this case, you can configure 5 GHz channels 149, 153, 157, 161, and 165, which are supported by the terminals.

Channels 184, 188, 192, and 196 on the 4.9 GHz frequency band can be used for radio scanning but cannot be used for channel calibration.

For three 5G radios, configure at least five calibration channels. For two 5G radios, configure at least three calibration channels.

Usage Guidelines

You can run the deny-threshold command to set the maximum number of times an AP rejects association requests of a STA for a static load balancing group. When a STA requests to associate with an AP radio in the static load balancing group, the AP rejects the association request of the STA if traffic is not balanced among radios in the group. When the number of consecutive association attempts of the STA exceeds the configured maximum number of rejection times, the AP allows the STA to associate with it regardless of whether traffic is balanced.

Usage Guidelines

When an AP is working on the manually planned channel, if radar signals are detected, the AP switches to a non-radar channel. The AP channel will be switched back to the manually planned channel after the configured switchback delay and legitimate aging time (30 minutes). A proper delay in switching back the DFS channel will prevent frequent channel switchovers.

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

After the DFS smart selection function is enabled, an AP working on the 5 GHz band detects radar signals. Upon detecting radar channels, the AP automatically switches to another channel to prevent radar interference.

The switched-to channel is a random non-radar channel and therefore may be the same as or close to the channel of surrounding 5 GHz radios, leading to severe interference and poor user experience. The DFS smart selection function is enabled by default to adjust the 5 GHz channel of an AP to one with the least interference.

After the dfs smart-selection disable command is executed, the DFS smart selection function is disabled, affecting user experience. Configure this function as required.

Precautions

The DFS smart selection function is valid only when the air scan is enabled.

Static load balancing group view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

After the load difference threshold for load balancing based on the number of users is configured using the sta-number gap-threshold command, an AP implements load balancing based on the difference between the number of users on different radios. The load balancing algorithm is as follows:

Load balancing algorithm based on the percentage of users: The AC calculates the load percentage of each radio in a load balancing group using the formula: Load percentage of a radio = (Number of associated users on the radio/Maximum number of users allowed on the radio) x 100%. The AC compares load percentages of all radios in the load balancing group and obtains the smallest load percentage value. When a user requests to associate with an AP radio, the AC calculates the difference between the radio's load percentage and the smallest load percentage value and compares the load difference with the threshold. If the difference is smaller than the threshold, the AC allows the user to associate with the radio. If not, the AC rejects the association request of the user. If users continue to send association requests to the AP and the maximum number of times the AP rejects users' association requests that is configured using the deny-threshold command for a static load balancing group, the AP allows user access.

The load balancing algorithm based on the actual number of users is similar to that based on the percentage of users. The only difference is that the former algorithm uses the number of users actually associated with radios to calculate the difference.

Precautions

If you configure the load difference threshold based on both the number of users and the percentage of users, only the latest configuration takes effect.

Example

# Set the load difference threshold for load balancing based on the percentage of users in the static load balancing group to 40%.

Two APs working in the same frequency band interfere with each other. For example, on a large-scale WLAN (a university campus network), different APs often use the same channel. When there are overlapping areas among these APs, co-channel interference exists, degrading network performance.

After the interference detect-enable command is executed to enable interference detection, an AP can detect adjacent-channel interference.

Usage Guidelines

WLAN wireless channels are vulnerable to interference in surrounding radio environments, and the service quality is therefore degraded. If interference detection is configured, a monitor AP can know the radio environment in real time and report alarms to the AC in a timely manner.

Interference detection enables an AP to detect AP co-channel interference, AP adjacent-channel interference, and STA interference.
  • AP co-channel interference: Two APs working on the same frequency band interfere with each other. For example, on a large-scale WLAN (a university campus network), different APs often use the same channel. When there are overlapping areas among these APs, co-channel interference exists, degrading network performance.
  • AP adjacent-channel interference: Two APs with different center frequencies have overlapping areas, resulting in adjacent-channel interference. Therefore, if APs are placed too close to each other or they have strong signals, more noise will be produced, degrading network performance.
  • STA interference: If there are many STAs that are managed by other APs around an AP, services of the STAs managed by the local AP may be affected.

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

You can use this command to add an AP radio to or delete an AP radio from a static load balancing group. When a STA requests to connect to an AP radio in a static load balancing group, the AC compares the load of the radio and other working radios in the load balancing group and determines whether to allow the STA to connect to the radio according to a load balancing algorithm.

Precautions

  • If dual-band APs are used, traffic is load balanced among APs working on the same frequency band.
  • Each load balancing group supports a maximum of 16 AP radios.
  • Under the agile distributed network architecture composed of the central AP and RUs, you only need to add radios of the RUs to a static load balancing group.
  • A radio configured with channel 184, 188, 192, or 196 on the 4.9 GHz frequency band cannot be used for load balancing.

Usage Scenario

The traditional radio power control function sets the power of an AP to a fixed value to keep the power of all STAs connecting to the AP the same.

You can run the power auto-adjust enable command to enable signal-strength-based power adjustment. This function enables an AP to detect the signal strength of a STA in a timely manner. If the AP detects that the signal strength of the STA is strong (for example, the STA is near the AP), the AP reduces its transmit power when sending packets. If the AP detects that the signal strength of the STA is weak (for example, the STA is far from the AP), the AP uses the normal transmit power to send radio signals.

  • If you specify a calibration channel set as the air scan channel set, the AP scans data on a few channels. This reduces the channel scanning time, increases the terminal location accuracy, and reduces burden on the device.
  • If you add only working channels of an AP to the air scan channel set, the AP only scans the working channels.

Example

# Configure an air scan channel set that contains all calibration channels.

Usage Guidelines

Usage Scenario

After the air scan period is configured using the scan-period command, an AP continuously scans surrounding radio signals in the configured period. After the period expires, the AP reports the collected information to an AC or server. The information is used for radio calibration, smart roaming, spectrum analysis, WLAN location, or WIDS data analysis.

Precautions

A longer air scan period indicates more collected data and a more accurate data analysis result. However, if the air scan period is set too large, WLAN services are affected. You are advised to use the default value.

You can run the smart-antenna training-interval command to set the smart antenna training interval. When the period since the last round of smart antenna training exceeds the specified interval, a new round of smart antenna training is triggered.

Configure the smart antenna training interval based on actual situations.
  • A short antenna training interval causes frequency antenna training and affects user services.
  • A long antenna training interval causes the device's failure to switch the antenna combination in time to adapt to WLAN environment changes.

When the default smart antenna training interval is restored, that is, smart antennas are trained in self-adaptation mode, the device adaptively calculates the antenna training interval based on the number of concurrent STAs.

Usage Guidelines

In the smart antenna algorithm, an AP uses different antenna combinations to send training packets for antenna training. During smart antenna training, the transmit end (AP) sends training packets to a receive end (STA). The receive end measures the PER and RSSI in the received packets, and then sends the PER and RSSI to the transmit end. The transmit end collects information about all antenna combinations and corresponding PERs and RSSIs to determine the optimal antenna combination for the receiver.

You can run the smart-antenna training-mpdu-number command to set the number of MPDUs sent by an AP to a STA during smart antenna training.

If the traffic rate, bandwidth, and air interface rate of the STA are high, set a small value. Otherwise, set a large value.

Usage Scenario

During the roaming steering for sticky STAs, real-time information about neighboring APs is required to determine the target AP. If STAs do not support 802.11k radio resource measurement, you can run the undo smart-roam advanced-scan disable command to enable the coordinated scanning function of smart roaming. In this way, APs can collect real-time information about neighboring APs through synchronized radio resource measurement, and generate a neighbor AP table of the STAs.

After the coordinated scanning function of smart roaming is enabled, radios switch channels to scan STA information while ensuring voice and video services. If voice and video services are affected, you can disable this function.

Usage Guidelines

Usage Scenario

On a traditional WLAN, when a STA is farther from an AP, the access rate of the STA becomes lower but the STA still associates with the AP without reinitiating a connection with the AP or roaming to another AP. This degrades user experience. To prevent this situation, configure the smart roaming function. When detecting that the SNR or access rate of a STA is lower than the specified threshold, the AP sends a Disassociation packet to the STA so that the STA can reconnect or roam to another AP.

Follow-up Procedure

Run the smart-roam roam-threshold { check-snr | check-rate } command to configure the trigger mode of smart roaming and the smart-roam roam-threshold { snr | rate } command to configure the smart roaming threshold. After that, APs forcibly disconnect STAs with SNR or access rate lower than the threshold.

Usage Guidelines

Usage Scenario

After smart roaming is enabled, you can run the smart-roam snr-margin command to set the SNR difference threshold that triggers terminal roaming. Before roaming, a STA compares the SNR of the current AP and neighboring AP and roams only when the SNR difference between the two APs is larger than the specified difference threshold.

There are two thresholds: higher and low SNR difference thresholds applicable to good and poor radio environments, respectively. A STA actively roams in good radio environments where the signal strength of the current AP is greater than or equal to 35 dB, and the SNR difference between the current AP and neighbor AP exceeds high-level-margin. In poor radio environments, the STA roams when the SNR of the current AP is smaller than 35 dB and the SNR difference between the current and neighbor APs is larger than low-level-margin.

You are advised to set high-level-margin larger than low-level-margin.

Prerequisites

The smart roaming function has been enabled using the undo smart-roam disable command.

Usage Guidelines

Usage Scenario

After smart roaming is enabled, you can run the smart-roam unable-roam-client expire-time command to set the aging time of "unable to roam" record for terminals. When the AC requests a terminal to roam but the terminal keeps sending association requests to the original AP or does not initiate an association request, the AC records the terminal as unable to roam and does not trigger terminal roaming within the specified time. After the aging time is reached, "unable to roam" record of the terminal is automatically cleared, and the system can trigger roaming of the terminal.

A terminal is recorded as unable to roam due to the following reasons:
  • Due to different software configurations, some terminals preferentially send association requests to APs with which they have once associated.
  • In some environments, terminals cannot scan APs with strong signals.
  • Terminals enter dormancy state and do not roam once they are forcibly disconnected.

The aging time to configure varies for different reasons. A large aging time is used for the software configuration reason so that the AP will trigger roaming of the terminals as less as possible. However, a small aging time is used in other situations so that the AP will attempt to trigger roaming of the terminals marked unable to roam.

Prerequisites

The smart roaming function has been enabled using the undo smart-roam disable command.

Usage Guidelines

Static load balancing limits the maximum number of AP radios to 16 and allows only radios on the same frequency band to join a load balancing group. Additionally, a load balancing group needs to be manually specified. Dynamic load balancing overcomes the limitations of static load balancing.

In dynamic load balancing mode, a STA sends a broadcast Probe Request frame to scan available APs. The APs that receive the Probe Request frame all report the STA information to the AC. The AC adds these APs to a load balancing group, and then uses a load balancing algorithm to determine whether to allow access from the STA.

Views

RRM profile view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

When a user requests to connect to an AP, the AP will count the total number of access users on all radios. If the total number of access users does not exceed the start threshold configured using the sta-load-balance dynamic sta-number start-threshold command, the AP does not implement dynamic load balancing. The AP implements dynamic load balancing only when the total number of access users on all radios exceeds the start threshold.

In dynamic load balancing mode, an AC uses a load balancing algorithm to determine whether to allow a user to associate with a radio. The load balancing algorithm is as follows:

Load balancing algorithm based on the percentage of users: When implementing dynamic load balancing, the AC calculates the load percentage of each radio in a load balancing group using the formula: Load percentage of a radio = (Number of associated users on the radio/Maximum number of users allowed on the radio) x 100%. The AC compares load percentages of all radios in the load balancing group and obtains the smallest load percentage value. When a user requests to associate with an AP radio, the AC calculates the difference between the radio's load percentage and the smallest load percentage value and compares the load difference with the threshold. If the difference is smaller than the threshold, the AC allows the user to associate with the radio. If not, the AC rejects the association request of the user. If the user continues sending association requests to this AP, the AC allows the user to associate with the AP when the number of consecutive association attempts of the user exceeds the maximum number of rejection times configured using the sta-load-balance dynamic deny-threshold command on the AC.

The load balancing algorithm based on the number of users is similar to that based on the percentage of users. The only difference is that the former algorithm uses the number of users actually associated with radios to calculate the difference.

Precautions

If you configure the load difference threshold based on both the number of users and the percentage of users, only the latest configuration takes effect.

Usage Scenario

When dynamic load balancing based on the channel usage is implemented, an AC calculates the channel usage of each member in a dynamic load balancing group. The AC then compares the channel usage values of all members in the dynamic load balancing group and obtains the smallest channel usage value. When a STA requests to associate with an AP radio, the AC calculates the difference between the radio's channel usage and the smallest channel usage value, and compares this difference with the specified threshold. If the difference is smaller than the threshold, the AC allows the STA to associate with the radio. If not, the AC performs dynamic load balancing calculation and allows the STA to associate with the radio with a lower load.

Usage Guidelines

After the RSSI threshold of member devices in a dynamic load balancing group is set an AP compares the RSSI of a STA with the configured RSSI threshold after receiving the Probe Request packet sent by the STA. If the STA's RSSI exceeds the configured RSSI threshold, the AP reports the STA information to the AC, and the AP is added to the dynamic load balancing group. Otherwise, the AP directly filters the STA information and does not report the information to the AC, and the AP will be not be added to the dynamic load balancing group.

Setting an RSSI threshold for member devices in a dynamic load balancing group is to filter APs with weak signals, so that STAs can be load balanced between APs with better signals. This prevents STAs from associating with APs with weak signals but light loads. This function does not affect STAs' going online.

You can run the sta-load-balance mode command to configure the dynamic load balancing mode based on the actual environment to provide better network experience for users.

  • Dynamic load balancing based on the channel usage uses a complex algorithm but is accurately implemented to ensure service quality. This mode is recommended when service types and traffic volumes differ greatly among users.
  • Dynamic load balancing based on the number of users is less accurate but uses a simple algorithm. This mode is recommended when most users have the same type of services and similar service traffic volumes.

Precautions

When configuring RUs to load balance traffic based on the channel usage, run the ap data-collection enable command to enable the RU data buffering function on the central AP. If this function is disabled, dynamic load balancing based on the channel usage does not take effect.

Example

# Configure dynamic load balancing based on the channel usage.

Usage Guidelines

Usage Scenario

When static load balancing based on the channel usage is implemented, an AC calculates the channel usage of each member in a static load balancing group. The AC then compares the channel usage values of all members in the static load balancing group and obtains the smallest channel usage value. When a STA requests to associate with an AP radio, the AC calculates the difference between the radio's channel usage and the smallest channel usage value, and compares this difference with the specified threshold. If the difference is smaller than the threshold, the AC allows the STA to associate with the radio. If not, the AC performs static load balancing calculation and allows the STA to associate with the radio with a lower load.

Example

# Set the channel usage difference threshold for load balancing in the static load balancing group to 30%.

Usage Guidelines

Usage Scenario

After the start threshold is configured for static load balancing based on the channel usage, an AP calculates the channel usage of the radio with which a STA associates when the STA requests to connect to the AP. If the channel usage does not exceed the start threshold, the STA access is permitted. If the channel usage exceeds the start threshold, the AP calculates the load difference for static load balancing based on the channel usage. You can run the channel-utilization gap-threshold command to configure the load difference threshold for static load balancing based on the channel usage.

Example

# Set the start threshold for static load balancing based on the channel usage to 60%.

Usage Guidelines

Usage Scenario

On WLANs where many users exist, such as WLANs in high density scenarios, users compete fiercely to occupy the channels as the number of online users increases. As a result, network quality deteriorates. To ensure network access experience of online users, configure the user CAC function. The user CAC function allows an AP to control user access based on the thresholds specified according to the radio channel usage, number of online users, or terminal SNR, which enables provisioning of high-quality network access services.

  • User CAC based on channel usage uses a complex algorithm but is accurately implemented to ensure service quality. This mode is recommended when service types and traffic volumes differ greatly among users.

  • User CAC based on the number of users is less accurate but uses a simple algorithm. This mode is recommended when most users have the same type of services and similar service traffic volumes.

  • SNR-based user CAC controls access from weak-signal users, applicable to scenarios where the WLAN has good signal coverage and weak signals only at the edge of WLAN coverage areas.

user CAC based on channel usage and user CAC based on the number of access users cannot be configured simultaneously, but either of them can be configured together with user CAC based on terminal SNR.

Prerequisites

The user CAC function based on channel usage has been enabled using the uac enable command.

Example

# Set the user CAC access and roaming thresholds both to 50%.
