Hierarchical management
Hierarchical management helps administrators manage large-scale access networks. It reduces the
administrator workload, and ensures each service group's independence and security.
• The IMC platform supports hierarchical management of users and devices.
• UAM supports hierarchical management of services.
System configuration
The system configuration is a general policy for UAM operation.
The system configuration includes the following settings:
• Global parameter settings—Specify whether to enable the self-service and preregistration service,
set the log storage period, and other global settings.
• Client upgrade configuration—Restrict the iNode client version that can be used by each user
group.
• Client secure configuration—Upgrade and maintain the iNode dictionary to prevent illegal clients
from accessing the network.
Self service
At the UAM self-service center, access users can view and modify user information, view access details,
modify user passwords, and clear the online information.
