DES-7200(config)# aaa group server radius auth-ll
DES-7200(config-gs-radius)# server 192.168.4.1

4.2.21 Configuring and Managing
Online Users
DES-7200’s devices provide management for authenticated users via SNMP. The
administrator can view the information of the authorized users via SNMP, and forcedly log off a
user. The user forcedly logged off must pass the authentication again before it can use
network resources.
This function calls for no configuration on the device.
4.2.22 Implementing User-IP
Binding
With our clients and by correctly configuring the Radius Server, you can implement unique
user-IP binding. A user must undergo authentication by using the IP address allocated by the
administrator. Otherwise, authentication will fail.
For this function, you do not need to configure the switch. The user needs to use our client and
the administrator needs to configure the Radius Server.
