The uac enable command enables user CAC.
The undo uac enable command disables user CAC.
By default, user CAC is disabled.
| Parameter | Description | Value |

client-snr |
Controls user access based on the terminal SNR. |

Usage Scenario
On WLANs where many users exist, such as WLANs in high density scenarios, users compete fiercely to occupy resources 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 number of online users or terminal SNR, which enables provisioning of high-quality network access services.
User CAC based on the number of users uses a simple algorithm. This mode is recommended when most users have the same type of services and similar service traffic volumes.
SNR-based user CAC controls access from weak-signal users, and is applicable to scenarios where the WLAN has good signal coverage and weak signals only at the edge of WLAN coverage areas.
CAC based on the number of users can be configured together with SNR-based CAC.
Follow-up Procedure
Run the uac client-number threshold command to set the user CAC threshold based on the number of users.
Run the uac client-snr threshold command to set the user CAC threshold based on terminal SNR.
Run the uac reach-access-threshold hide-ssid command to configure the AP to automatically hide its SSID when the number of users reaches the user CAC threshold for new users.
