Configuring Static Load Balancing

Context

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.

In static load balancing mode, APs providing the same services are manually added to a load balancing group. After a STA connects to a WLAN, the AC uses the load balancing algorithm to measure the dual-band capability of the STA, AP load, and AP signal quality, and steers the STA to a better AP.

If dual-band APs are used, traffic is load balanced among radios working on the same frequency band.
Each load balancing group supports a maximum of 16 APs.
Under the agile distributed network architecture composed of the central AP and RUs, you only need to add radios of the RUs to a static load balancing group.

Procedure

Run system-view
The system view is displayed.
Run wlan
The WLAN view is displayed.
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.
Run member { { ap-name ap-name | ap-id ap-id } [ radio radio-id ] }&<1-8>
An AP radio is added to the static load balancing group.

By default, no AP radio is added to a static load balancing group.
(Optional) Configure the static load balancing mode and related parameters.
Configure static load balancing based on the number of users.
1. Run sta-number start-threshold start-threshold-value
  The start threshold for static load balancing based on the number of users is set.
  
  By default, the start threshold for load balancing in a static load balancing group is 10.
2. Run sta-number gap-threshold { percentage percentage-value | number number-value }
  The load difference threshold for static load balancing based on the number of users is set.
  
  By default, the load difference threshold of a static load balancing group is specified based on the number of users, and the default value is 3.
3. (Optional) Run rssi-threshold rssi-threshold
  The RSSI threshold of members in the static load balancing group is set.
  
  By default, the RSSI threshold of member devices in a static load balancing group is –65 dBm.
4. (Optional) Run rssi-diff-gap diff-gap-threshold
  The RSSI difference threshold of members in the static load balancing group is set.
  
  By default, the RSSI difference threshold of members in a static load balancing group is 5 dB.
5. (Optional) Run btm-fail-times btm-fail-times
  The number of attempts to steer STAs in BTM mode is set.
  
  By default, the maximum number of attempts to steer STAs in BTM mode is 5.
6. (Optional) Run deauth-fail-times deauth-fail-times
  The number of attempts to steer STAs in Deauthentication mode is set.
  
  By default, the maximum number of attempts to steer STAs in deauthentication mode is 2.
7. (Optional) Run steer-restrict probe-threshold probe-threshold
  The number of times non-target APs suppress STA Probe frames during STA steering is set.
  
  By default, the maximum number of times non-target APs suppress probing of STAs during STA steering is 5.
8. (Optional) Run steer-restrict auth-threshold auth-threshold
  The number of times non-target APs suppress STA Authentication frames during STA steering is set.
  
  By default, the maximum number of times non-target APs suppress authentication of STAs during STA steering is 0.
9. (Optional) Run steer-restrict restrict-time restrict-time
  The time for suppressing STA association with non-target APs during STA steering is set.
  
  By default, the duration within which non-target APs suppress association of STAs during STA steering is 5 seconds.

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.
