Configuring the portal fail-permit function
Perform this task to configure the portal fail-permit function on an interface. When the access device
detects that the portal authentication server is unreachable, it allows users on the interface to have
network access without portal authentication.
If you enable fail-permit for both a portal authentication server and a portal Web server on an interface,
the interface disables portal authentication when either server is unreachable and resumes portal
authentication when both servers are reachable. After portal authentication resumes, unauthenticated
users must pass portal authentication to access the network. Users who have passed portal authentication
before the fail-permit event can continue accessing the network.
To configure portal fail-permit:

server-name fail-permit
By default, portal fail-permit is
disabled for a portal Web server.
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.
If you configure the BAS-IP or BAS-IPv6 attribute on an interface, the device uses the configured BAS-IP
or BAS-IPv6 address as the source IP address of the portal notifications sent from the interface to the
portal authentication server. Otherwise, the source IP address is the IP address of the interface.
