WLAN radio load balancing commands

The AP models and serial numbers in this document are used only as examples. Support for AP models and serial numbers depends on the AC model.

wlan radio-load-balance access-denial

Use wlan radio-load-balance access-denial to set the maximum number of denials for association requests.

Use undo wlan radio-load-balance access-denial to restore the default.

Syntax

wlan radio-load-balance access-denial access-denial

undo wlan radio-load-balance access-denial

Default

The maximum number of denials is 3 for association requests.

Views

System view

Predefined user roles

network-admin

Parameters

access-denial: Specifies the maximum number of denials for association requests, in the range of 2 to 10.

Usage guidelines

If the number of times that a radio rejects a client reaches the specified maximum number of denials for association requests, the radio accepts the association request from the client.

Examples

# Set the maximum number of denials to 4 for association requests.

<Sysname> system-view

[Sysname] wlan radio-load-balance access-denial 4

wlan radio-load-balance enable

Use wlan radio-load-balance enable to enable WLAN radio load balancing.

Use undo wlan radio-load-balance enable to disable WLAN radio load balancing.

Syntax

wlan radio-load-balance enable [ mode session value [ gap gap-value | band-ratio 5g-proportion 2.4g-proportion ] [ report-time time ] ]

undo wlan radio-load-balance enable

Default

WLAN radio load balancing is disabled.

Parameters

session value: Specifies the session threshold value in the range of 1 to 120.

gap gap-value: Specifies the session gap threshold value in the range of 1 to 12. The session gap is the gap between a radio and the radio that has the fewest clients within the same AC.

band-ratio 5g-proportion 2.4g-proportion: Specifies the ratio of clients associated with all 5 GHz neighbor radios to clients associated with all 2.4 GHz neighbor radios of a client. The value range is 1 to 5 for both the 5g-proportion and 2.4g-proportion arguments.

report-time time: Specifies the time to wait before an AP reports information about a client for the first time. The value range for the time argument is 500 to 5000 milliseconds and the default value is 1000 milliseconds.

Usage guidelines

The AC supports session-mode radio load balancing and the following radio load balancing types:

·     Session gap threshold based—The AC performs radio load balancing when the following conditions are met:

¡     The number of clients associated with a radio reaches the session threshold.

¡     The session gap between the radio and the radio that has the fewest clients reaches the session gap threshold.

·     Band ratio based—The AC performs radio load balancing in the following scenarios:

Scenario 1

¡     A client requests to associate with a 5 GHz radio.

¡     The number of clients associated with the 5 GHz radio reaches the session threshold.

¡     The ratio of clients associated with all 5 GHz neighbor radios to clients associated with all 2.4 GHz neighbor radios of the client is larger than the band ratio.

Scenario 2

¡     A client requests to associate with a 2.4 GHz radio.

¡     The number of clients associated with the 2.4 GHz radio reaches the session threshold.

¡     The ratio of clients associated with all 5 GHz neighbor radios to clients associated with all 2.4 GHz neighbor radios of the client is smaller than the band ratio.

When an AP receives the probe request from a client for the first time, the AP waits for the specified time period before it sends the client information to the AC. The AC creates a neighbor radio table for a client based on the information received from APs. To ensure data accuracy and save resources, set an appropriate wait time period.

If you do not specify a radio load balancing type, the session gap threshold based type is used. The session threshold is 50, and the session gap threshold 10.

 

 

NOTE:

Neighbor radios of a client refer to all radios that receive requests from the client.

Examples

# Enable WLAN radio load balancing.

<Sysname> system-view

[Sysname] wlan radio-load-balance enable mode session 4 gap 3

wlan radio-load-balance overload-5g ssid-hide

Use wlan radio-load-balance overload-5g ssid-hide enable to enable overloaded 5 GHz radios to hide SSIDs.

Use wlan radio-load-balance overload-5g ssid-hide disable to disable overloaded 5 GHz radios from hiding SSIDs.

Use undo wlan radio-load-balance overload-5g ssid-hide to restore the default.

Syntax

wlan radio-load-balance overload-5g ssid-hide { disable | enable [ session value [ gap gap-value ] ] }

undo wlan radio-load-balance overload-5g ssid-hide

Default

In AP view, an AP uses the configuration in AP group view.

In AP group view, overloaded 5 GHz radios do not hide SSIDs.

Parameters

session value: Specifies the session threshold value in the range of 1 to 120. The default value is 40.

gap gap-value: Specifies the session gap threshold value in the range of 1 to 24. The default value is 10.

Usage guidelines

After you configure this command, a 5 GHz radio hides its SSID in beacon frames when the following conditions are met:

·     The number of clients associated with the 5 GHz radio reaches the session threshold.

·     The session gap between the 5 GHz radio and another 5 GHz radio on the same AP reaches the session gap threshold.

The 5 GHz radio stops hiding its SSID in beacon frame when either of the following conditions are met:

·     The number of clients associated with the 5 GHz radio falls below the session threshold.

·     The session gap between the 5 GHz radio and another 5 GHz radio on the same AP falls below the session gap threshold.

As a best practice, enable this feature when a large number of clients exist in the network.

This feature takes effect only when an AP has multiple 5 GHz radios.

Examples

# Enable overloaded 5 GHz radios of AP ap1 to hide SSIDs.

<Sysname> system-view

[Sysname] wlan ap ap1 model WA4320i-ACN

[Sysname-wlan-ap-ap1] wlan radio-load-balance overload-5g ssid-hide enable session 20 gap 5

# Enable overloaded 5 GHz radios of APs in AP group group1 to hide SSIDs.

wlan radio-load-balance rssi-threshold

Use wlan radio-load-balance rssi-threshold to set the received signal strength indicator (RSSI) threshold.

Use undo wlan radio-load-balance rssi-threshold to restore the default.

Syntax

wlan radio-load-balance rssi-threshold rssi-threshold

undo wlan radio-load-balance rssi-threshold

Default

The RSSI threshold is 25.

Views

System view

Predefined user roles

network-admin

Parameters

rssi-threshold: Specifies the RSSI threshold in the range of 5 to 100.

Usage guidelines

If a radio detects that the RSSI of a client is lower than the specified RSSI threshold, the radio ignores the association requests of the client.

Examples

# Set the RSSI threshold to 40.

<Sysname> system-view

[Sysname] wlan radio-load-balance rssi-threshold 40
