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 or portal Web 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 does the following:
• Disables portal authentication when either server is unreachable.
• 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:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view. interface interface-type interface-number N/A
3. Enable portal
fail-permit for a portal
authentication server.
portal [ ipv6 ] fail-permit server
server-name
By default, portal fail-permit is
disabled for a portal
authentication server.
4. Enable portal
fail-permit for a portal
Web server.
portal [ ipv6 ] apply web-server
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.
