Configuring BAS-IP for unsolicited portal packets sent to the portal authentication server
If the device runs Portal 2.0, the unsolicited packets sent to the portal authentication server must carry the BAS-IP attribute. If the device runs Portal 3.0, the unsolicited packets sent to the portal authentication server must carry the BAS-IP or BAS-IPv6 attribute.
If IPv4 portal authentication is enabled on an interface, you can configure the BAS-IP attribute on the interface. If IPv6 portal authentication is enabled on an interface, you can configure the BAS-IPv6 attribute on the interface.
The device uses the configured BAS-IP or BAS-IPv6 address as the source IP address of the portal notifications sent to the portal authentication server. If you do not configure the BAS-IP or BAS-IPv6 attribute, the source IP address is the IP address of the packet's output interface.
During a re-DHCP portal authentication or mandatory user logout process, the device sends portal notification packets to the portal authentication server. For the authentication or logout process to complete, make sure the BAS-IP/BAS-IPv6 attribute is the same as the device IP or IPv6 address specified on the portal authentication server.
To configure the BAS-IP attribute for unsolicited portal packets sent to the portal authentication server:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter interface view. | interface interface-type interface-number | N/A |
3. Configure BAS-IP for IPv4 portal packets sent to the portal authentication server. | portal bas-ip ipv4-address | By default:
|
4. Configure BAS-IPv6 for IPv6 portal packets sent to the portal authentication server. | portal bas-ipv6 ipv6-address | By default:
