load-balancing [balance-ap-loads|balance-band-loads|balance-channel-loads [2.4GHz|5GHz]]
load-balancing Configures the following load balancing parameters: ap-loads, band-loads, and channel-loads.
balance-ap-loads Enables neighbor AP load balancing. This option distributes the access point‘s radio load amongst other controller managed access point radios. This option is disabled by default.
balance-band-loads Enables balancing of the total band load amongst neighbors. This option balances the access point‘s radio load by assigning a ratio to both the 2.4 GHz and 5.0 GHz bands. Balancing radio load by band ratio allows an administrator to assign a greater weight to radio traffic on either the 2.4 GHz or 5.0 GHz band. This option is disabled by default.
balance-channel-loads [2.4GHz|5GHz] Enables the following:
  • 2.4GHz – Channel load balancing on 2.4 GHz band. This option is disabled by default.

    Balances the access point‘s 2.4 GHz radio load across channels supported within the country of deployment. This can prevent congestion on the 2.4 GHz radio if a channel is over utilized.

  • 5GHz – Channel load balancing on 5.0 GHz band. This option is disabled by default.

    Balances the access point‘s 5.0 GHz radio load across channels supported within the country of deployment. This can prevent congestion on the 5.0 GHz radio if a channel is over utilized.

 
load-balancing band-control-strategy [distribute-by-ratio|prefer-2.4GHz| prefer-5GHz]
load-balancing band-control-strategy Configures a band control strategy

By default, this option steers 5.0 GHz-capable clients to the 5.0 GHz band. When an access point hears a request from a client to associate on both the 2.4 GHz and 5.0 GHz bands, it knows the client is capable of operation in 5.0 GHz. Band steering steers the client by responding only to the 5.0 GHz association request and not the 2.4 GHz request. Consequently, the client only associates in the 5.0 GHz band.
distribute-by-ratio Distributes clients to either band according to the band-ratio
prefer-2.4GHz Nudges all dual-band clients to 2.4 GHz band
prefer-5GHz Nudges all dual-band clients to 5.0 GHz band. This is the default setting. 
load-balancing band-ratio [2.4GHz|5GHz] [0|<1-10>]
load-balancing band-ratio Configures the relative loading of 2.4 GHz band and 5.0 GHz band.This allows an administrator to weight client traffic load if wishing to prioritize client traffic load on the 2.4 GHz or the radio band. The higher the value set, the greater the weight assigned to radio traffic load on the 2.4 GHz or 5.0 GHz radio band.
2.4GHz [0|<1-10>] Configures the relative loading of 2.4 GHz band
  • 0 – Selecting ‘0‘ steers all dual-band clients preferentially to the other band
  • <0-10> – Configures a relative load as a number from 0 - 10. The default is 0.
5ghz [0|<1-10>] Configures the relative loading of 5.0 GHz band
  • 0 – Selecting ‘0‘ steers all dual-band clients preferentially to the other band
  • <0-10> – Configures a relative load as a number from 0 - 10. The default is 1.
 
load-balancing group-id <GROUP-ID>
load-balancing group-id <GROUP-ID> Configures group ID to facilitate load balancing
  • <GROUP-ID> – Specify the group ID. This option is enabled only when a group ID is configured.
 
load-balancing neighbor-selection-strategy [use-common-clients|use-roam-notification|
use-smart-rf]
load-balancing neighbor-selection-strategy Configures a neighbor selection strategy. The options are: use-common-clients, use-roam-notification, and use-smart-rf
use-common-clients Selects neighbors based on probes from clients common to neighbors. This option is enabled by default.
use-roam-notification Selects neighbors based on roam notifications from roamed clients. This option is enabled by default.
use-smart-rf Selects neighbors detected by Smart RF. This option is enabled by default.
