uac client-number threshold

Function

The uac client-number threshold command configures the user CAC threshold based on the number of users.

The undo uac client-number threshold command restores the default user CAC threshold based on the number of users.

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

Format

uac client-number threshold access access-threshold [ roam roam-threshold ]

undo uac client-number threshold

Parameters

Parameter	Description	Value
access access-threshold	Specifies the user CAC access threshold based on the number of users.	The value is an integer that ranges from 1 to 512.
roam roam-threshold	Specifies the user CAC roaming threshold based on the number of users. This threshold is the total number of users who can be associate with the AP, including all local and reassociated roaming users.	The value is an integer that ranges from 1 to 512.

Usage Guidelines

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.

The user CAC access threshold is invalid for roaming users. For example, the user CAC access threshold is 20, and the user CAC roaming threshold is 24. If 20 local users have already connected to the network, not more local users can connect to the network but another four roaming users can.

CAC is implemented in the following modes:

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.

Prerequisites

The user CAC function based on the number of users has been enabled using the uac client-number enable command.

Example

# Set the user CAC access threshold based on the number of users to 50 and the roaming threshold to 60.
