portal server
portal { bas-ip | bas-ipv6 } (interface view)
Use portal { bas-ip | bas-ipv6 } to configure the BAS-IP or BAS-IPv6 attribute carried in the portal
packets sent to the portal authentication server.
Use undo portal { bas-ip | bas-ipv6 } to restore the default.
Syntax
portal { bas-ip ipv4-address | bas-ipv6 ipv6-address }
undo portal { bas-ip | bas-ipv6 }
Default
The BAS-IP attribute of an IPv4 portal reply packet sent to the portal authentication server is the
source IPv4 address of the packet. The BAS-IPv6 attribute of an IPv6 portal reply packet sent to the
portal authentication server is the source IPv6 address of the packet.
The BAS-IP attribute of an IPv4 portal notification packet sent to the portal authentication server is
the IPv4 address of the packet's output interface. The BAS-IPv6 attribute of an IPv6 portal
notification packet sent to the portal authentication server is the IPv6 address of the packet's output
interface.

Parameters
ipv4-address: Specifies BAS-IP for portal packets sent to the portal authentication server. This
attribute must be the IPv4 address of an interface on the device. It cannot be 0.0.0.0, 1.1.1.1, a class
D address, a class E address, or a loopback address.
ipv6-address: Specifies BAS-IPv6 for portal packets sent to the portal authentication server. This
attribute must be the IPv6 address of an interface on the device. It cannot be a multicast address, an
all-0 address, or a link-local address.
Usage guidelines
If the device runs Portal 2.0, unsolicited portal packets (such as a logout notification packet) sent to
the portal authentication server must carry the BAS-IP attribute. If the device runs Portal 3.0,
unsolicited portal packets sent to the portal authentication server must carry the BAS-IP or BAS-IPv6
attribute.
After this command takes effect, the source IP address for unsolicited notification portal packets the
device sends to the portal authentication server is the configured BAS IP address. Otherwise, the
source IP address of the packets is the IP address of the packet output interface.
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 H3C IMC server or the portal authentication mode on the
interface is re-DHCP.
•
The portal device IP address specified on the portal authentication server is not the IP address
of the portal packet output interface.
