WLAN radio load balancing commands

 

display wlan radio-load-balance status service-template

Use display wlan radio-load-balance status service-template to display load balancing information for radios that are bound to a service template.

Syntax

display wlan radio-load-balance status service-template template-name client mac-address

Views

Predefined user roles

network-admin

network-operator

Parameters

template-name: Specifies a service template by its name, a case-insensitive string of 1 to 63 characters.

client mac-address: Displays information about radios that have detected the specified client. The mac-address argument represents the MAC address of the client and is in H-H-H format.

Examples

# Display load balancing information for radios that are bound to service template st1 and that detect the client with MAC address 702d-2249-33bf.

<Sysname> display wlan radio-load-balance status service-template st1 client 702d-2249-33bf

Field

Description

Current radio load-balance mode

Session mode.

Threshold

Session threshold.

Gap

Session gap threshold. (This field is displayed only when the session gap threshold is configured.)

Band ratio (5G/2.4G)

Ratio of clients associated with 5 GHz radios to clients associated with 2.4 GHz radios.

(This field is displayed only when the ratio of clients associated with 5 GHz radios to clients associated with 2.4 GHz radios is configured.)

APID

AP ID.

RID

Radio ID

Session

Number of clients associated with the radio.

Balanced(Y/N)

Load balancing status:

·         Y—The radio has been load balanced.

·         N—The radio has not been load balanced.

 

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

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 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.

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
