Band navigation commands

wlan band-navigation aging-time

Use wlan band-navigation aging-time to set the client information aging time.

Use undo wlan band-navigation aging-time to restore the default.

Syntax

wlan band-navigation aging-time aging-time

undo wlan band-navigation aging-time

Default

The client information aging time is 180 seconds.

network-admin

Parameters

aging-time: Specifies the client information aging time in the range of 10 to 600 seconds.

Usage guidelines

When an AP receives an association request from a client, the AP records the client's information and starts the client information aging timer. If the AP receives a probe request or association request from the client before the aging timer expires, the AP refreshes the client information and resets the client information aging timer. If the AP does not receive any probe requests or association requests from the client before the aging timer expires, the AP deletes the client's information.

Configure an appropriate client information aging time to ensure both client association and system resource efficiency.

Examples

# Set the client information aging time to 50 seconds.

<Sysname> system-view

[Sysname] wlan band-navigation aging-time 50

wlan band-navigation balance access-denial

Use wlan band-navigation balance access-denial to set the maximum number of denials for 5 GHz association requests.

Use undo wlan band-navigation balance access-denial to restore the default.

Syntax

wlan band-navigation balance access-denial access-denial

undo wlan band-navigation balance access-denial

Default

The maximum number of denials for 5 GHz association requests is 1.

Parameters

access-denial: Specifies the maximum number of denials for 5 GHz association requests, in the range of 1 to 10.

Usage guidelines

If the number of times that a 5 GHz radio rejects a client reaches the specified maximum number, the radio accepts the association request of the client.

Examples

# Set the maximum number of denials to 5 for 5 GHz association requests.

[Sysname] wlan band-navigation balance access-denial 5

wlan band-navigation balance session

Use wlan band-navigation balance session to configure load balancing for band navigation.

Use undo wlan band-navigation balance session to restore the default.

Syntax

wlan band-navigation balance session session [ gap gap ]

undo wlan band-navigation balance session

Default

Load balancing is disabled for band navigation.

network-admin

Parameters

session: Specifies the client number threshold for the 5 GHz radio, in the range of 2 to 255.

gap: Specifies the threshold for the client number gap between the 5 GHz radio and the radio that has the fewest clients. The value range for this argument is 1 to 8 and the default value is 4.

Usage guidelines

If you enable band navigation but do not enable load balancing, the AC directs dual-band clients to the 5 GHz radio.

The AP rejects the 5 GHz association request of a client when the following conditions are met:

·     The number of clients on the 5 GHz radio reaches the specified threshold.

·     The client number gap between the 5 GHz radio and the radio that has the fewest clients reaches the specified threshold.

Examples

# Enable load balancing for band navigation, and set the client number threshold and session gap threshold to 10 and 5, respectively.

<Sysname> system-view

[Sysname] wlan band-navigation balance session 10 gap 5

wlan band-navigation enable

Use wlan band-navigation enable to enable band navigation globally.

Use undo wlan band-navigation enable to restore the default.

Syntax

wlan band-navigation enable

undo wlan band-navigation enable

Default

Band navigation is disabled globally.

Usage guidelines

For band navigation to take effect, make sure fast association is disabled for the wireless service that the clients use.

Band navigation takes effect on a fat AP when you enable band navigation globally.

Examples

# Enable band navigation globally.

[Sysname] wlan band-navigation enable

wlan band-navigation rssi-threshold

Use wlan band-navigation rssi-threshold to set the received signal strength indicator (RSSI) threshold for band navigation.

Use undo wlan band-navigation rssi-threshold to restore the default.

Syntax

wlan band-navigation rssi-threshold rssi-threshold

undo wlan band-navigation rssi-threshold

Default

The RSSI threshold for band navigation is 15.

System view

Predefined user roles

network-admin

Parameters

rssi-threshold: Specifies the RSSI threshold for band navigation, in the range of 5 to 100.

Usage guidelines

A client might be detected by multiple radios. A 5 GHz radio rejects the association request of a client if the client's RSSI is lower than the band navigation RSSI threshold.

Examples

# Set the RSSI threshold for band navigation to 40.

<Sysname> system-view

[Sysname] wlan band-navigation rssi-threshold 40
