Configuring The Portal Fail-Permit Feature; Configuring Bas-Ip For Portal Packets Sent To The Portal Authentication Server - HP FlexNetwork 10500 Series Security Configuration Manual

Configuring the portal fail-permit feature

Perform this task to configure the portal fail-permit feature 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
1. Enter system view.
2. Enter VLAN interface
view.
3. Enable portal
fail-permit for a portal
authentication server.
4. Enable portal
fail-permit for a portal
Web server.
Configuring BAS-IP for 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.
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 or IPv6 address
specified on the portal authentication server.
To configure the BAS-IP attribute for portal packets sent to the portal authentication server:
Step
1. Enter system view.
