Configuring the BAS-IP or BAS-IPv6 attribute

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.

After this attribute is configured, the source IP address for unsolicited notification portal packets the device sends to the portal authentication server is the configured BAS-IP or BAS-IPv6 address. If the attribute is not configured, the source IP address of the portal packets is the IP address of the packet 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 address specified on the portal authentication server.

You must configure the BAS-IP or BAS-IPv6 attribute on a portal authentication-enabled interface if the following conditions are met:

• The portal authentication server is an HPE IMC server.

• The portal device IP address specified on the portal authentication server is not the IP address of the portal packet output interface.

3. Configure the BAS-IP or BAS-IPv6 attribute.

   IPv4:

   portal bas-ip ipv4-address

   By default, the BAS-IP attribute of an IPv4 portal reply packet is the source IPv4 address of the packet. The BAS-IP attribute of an IPv4 portal notification packet is the IPv4 address of the packet's output interface.

   IPv6:

   portal bas-ipv6 ipv6-address

   By default, the BAS-IPv6 attribute of an IPv6 portal reply packet is the source IPv6 address of the packet. The BAS-IPv6 attribute of an IPv6 portal notification packet is the IPv6 address of the packet's output interface.
