undo access-limit 
View 
ISP domain view 
Parameter 
disable: No limit to the supplicant number in the current ISP domain. 
enable max-user-number: Specifies the maximum supplicant number in the current 
ISP domain, ranging from 1 to 2312. 
Description 
Use the access-limit command to configure a limit to the amount of supplicants in the 
current ISP domain. 
Use the undo access-limit command to restore the limit to the default setting. 
By default, there is no limit to the amount of supplicants in the current ISP domain.  
This command limits the amount of supplicants contained in the current ISP domain. 
The supplicants may contend with each other for the network resources. So setting a 
suitable limit to the amount will guarantee the reliable performance for the existing 
supplicants. 
Example 
# Set a limit of 500 supplicants for the ISP domain, huawei163.net. 
[Quidway-isp-huawei163.net] access-limit enable 500
