z 

Configuration of authentication subnets applies to only Layer 3 portal authentication. 

z 

In direct authentication mode, the authentication subnet is 0.0.0.0/0. 

z 

In re-DHCP authentication mode, the authentication subnet of an interface is the subnet to which 

the private IP address of the interface belongs. 

 

After you specify the source IP address for portal packets to be sent, the IP address will be used for 

packet exchanging between the access device and the portal server. 

Follow these steps to specify the source IP address for portal packets to be sent: 

Enter system view 

— 

Enter interface view 

interface interface-type 
interface-number 

— 

Specify the source IP address 
for portal packets to be sent 

portal nas-ip ip-address 

Optional 

By default, there is no source IP 
address specified for portal 
packets and the IP address of 
the user login interface will be 
used as the source IP address 
of the portal packets.  

 

Logging out a user terminates the authentication process for the user or removes the user from the 

authenticated users list.  

Follow these steps to log out users: 

Enter system view 

— 

Log out users 

portal delete-user { ip-address 
| all | interface interface-type 
interface-number } 

Required 

 

After you specify a mandatory authentication domain for an interface, the device will use the mandatory 

authentication domain for authentication, authorization, and accounting (AAA) of the portal users on the 

interface, ignoring the domain names carried in the usernames. Thereby, you can specify different 

authentication domains for different interfaces as needed. 

Follow these steps to specify an authentication domain for an interface:
