Configuring Static Load Balancing

Configuring Static Load Balancing


The load balancing function applies to scenarios where there is a high degree of overlap between APs' coverage ranges. If APs engaged in load balancing are far from each other, a STA may connect to a distant AP, which affects wireless experience of users.

When the load difference between APs reaches the load difference threshold, some STAs may access the network slowly because the APs will reject access requests of STAs according to the load balancing algorithm. If a STA continues sending association requests to an AP, the AP allows the STA to associate when the number of consecutive association attempts of the STA exceeds the maximum number of rejection times.

In static load balancing mode, APs providing the same services are manually added to a load balancing group. When a STA needs to access a WLAN, it sends an Association Request packet to an AC through an AP. The AC determines whether to permit access from the STA according to a load balancing algorithm. The implementation of static load balancing must meet the following conditions.
  • 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.


  1. Run system-view

    The system view is displayed.

  2. Run wlan ac

    The WLAN view is displayed.

  3. Run sta-load-balance static-group name group-name

    A static load balancing group is created and the static load balancing group view is displayed.

    By default, no static load balancing group is available in the system.

  4. Run member { { ap-name ap-name | ap-id ap-id } [ radio radio-id ] } &<1-16>

    An AP radio is added to the static load balancing group.

    By default, no AP radio is added to a static load balancing group.

  5. (Optional) Run start-threshold start-threshold-value

    The start threshold for load balancing in the static load balancing group is configured.

    By default, the start threshold for load balancing in a static load balancing group is 10.

  6. (Optional) Run gap-threshold gap-threshold-value

    The load difference threshold is configured for the static load balancing group.

    By default, the load difference threshold in a static load balancing group is 20%.

  7. Run quit

    Return to the WLAN view.

  8. Run commit { all | ap-name ap-name | ap-id { ap-id1 [ to ap-id2 ] } &<1-10> }

    Configurations are delivered to APs.

Verifying the Configuration

  • Run the display sta-load-balance static-group { all | name group-name } command to check information about a static load balancing group.
