Configuring User CAC

Configuring User CAC

Context

On WLANs where many users exist, such as WLANs in high density scenarios, users compete fiercely to occupy the channels as the number of online users increases. As a result, network quality deteriorates. To ensure network access experience of online users, configure the user CAC function. The user CAC function allows an AP to control user access based on the thresholds specified according to the radio channel usage, number of online users, or terminal SNR, which enables provisioning of high-quality network access services.

CAC is implemented in three modes:
  • CAC based on channel usage uses a complex algorithm but is accurately implemented to ensure service quality. This mode is recommended when service types and traffic volumes differ greatly among users.

  • CAC based on the number of users is less accurate but uses a simple algorithm. This mode is recommended when most users have the same type of services and similar service traffic volumes.

  • SNR-based CAC controls access from weak-signal users, This mode is recommended when the WLAN has good signal coverage and weak signals only at the edge of WLAN coverage areas.

Pre-configuration Tasks

Before configuring user CAC, perform the task of WLAN Service Configuration.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    wlan

    The WLAN view is displayed.

  3. Run:

    rrm-profile name profile-name

    The RRM profile view is displayed.

  4. Configure the CAC implementation mode and threshold, and enable CAC.

    You can configure any of the preceding CAC implementation modes as required.

    CAC based on channel usage and CAC based on the number of access users cannot be configured simultaneously, but either of them can be configured together with CAC based on terminal SNR.

    • CAC based on the number of users

      1. Run the uac client-number enable command to enable CAC based on the number of users.
      2. Run the uac client-number threshold access access-threshold [ roam roam-threshold ] command to configure the CAC threshold based on the number of users.
        NOTE:

        By default, the user CAC access and roaming thresholds based on the number of users are both 64.

    • CAC based on channel usage

      1. Run the uac channel-utilization enable command to enable CAC based on channel usage.
      2. Run the uac channel-utilization threshold access access-threshold [ roam roam-threshold ] command to configure the CAC threshold based on channel usage.
        NOTE:

        By default, the user CAC access and roaming thresholds based on channel usage are both 80%.

    • CAC based on terminal SNR

      1. Run the uac client-snr enable command to enable CAC based on terminal SNR.
      2. Run the uac client-snr threshold threshold command to configure the CAC threshold based on terminal SNR.
        NOTE:

        By default, the user CAC threshold based on terminal SNR is 20 dB.

  5. (Optional) Run:

    uac reach-access-threshold hide-ssid

    The AP is configured to automatically hide its SSID when the CAC threshold is reached.

    By default, an AP does not hide its SSID when the CAC threshold is reached.

  6. Run:

    quit

    Return to the WLAN view.

  7. Bind the RRM profile to a radio profile.
    1. Run the radio-2g-profile name profile-name or radio-5g-profile name profile-name command to enter the 2G or 5G radio profile view.
    2. Run the rrm-profile profile-name command to bind the RRM profile to the 2G or 5G radio profile.
    3. Run the quit command to return to the WLAN view.
  8. Bind the radio profile to an AP group or a specific AP. For the detailed procedure, see Binding a Radio Profile.
  9. Run:

    quit

    Return to the WLAN view.

  10. 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 rrm-profile name profile-name command to check settings of user CAC parameters.
  • Run the display radio-2g-profile name profile-name command to check the RRM profile referenced by a 2G radio profile.
  • Run the display radio-5g-profile name profile-name command to check the RRM profile referenced by a 5G radio profile.
