Enabling Layer 3 Portal Authentication; Controlling Access Of Portal Users; Configuring A Portal-Free Rule - HP 3600 v2 Series Configuration Manual

Enabling Layer 3 portal authentication

Before enabling Layer 3 portal authentication on an interface, make sure:
• An IP address is configured for the interface.
The interface is not added to any port aggregation group.
•
The portal server referenced by the interface already exists.
•
Layer 2 portal authentication is not enabled on any ports.
•
Follow these guidelines when you enable Layer 3 portal authentication:
You cannot enable portal authentication on a Layer 3 interface in a port aggregation group. If an
•
interface is enabled with portal authentication, you cannot add it to a port aggregation group.
The destination port number that the device uses for sending unsolicited packets to the portal server
•
must be the same as the port number that the remote portal server actually uses.
• Cross-subnet authentication mode (portal server server-name method layer3) does not require
Layer 3 forwarding devices between the access device and the authentication clients. However, if
Layer 3 forwarding devices exist between the authentication client and the access device, you must
select the cross-subnet portal authentication mode.
In re-DHCP authentication mode, a client can use a public IP address to send packets before
•
passing portal authentication. However, responses to the packets are restricted.
An IPv6 portal server does not support the re-DHCP portal authentication mode.
•
You can enable both an IPv4 portal server and an IPv6 portal server for Layer 3 portal
•
authentication on an interface, but you cannot enable two IPv4 or two IPv6 portal servers on the
interface.
To enable Layer 3 portal authentication:
Step
1. Enter system view.
2. Enter interface view.

3.
authentication on the
interface.
NOTE:
The portal server and its parameters can be deleted or modified only when the portal server is not
referenced by any interface.
