Step Command Remarks
4. (Optional.) Configure the
destination UDP port
number used by the device
to send unsolicited portal
packets to the portal
authentication server.
port port-id
By default, the UDP port number
is 50100.
This port number must be the
same as the listening port
number specified on the portal
authentication server.
Configuring a portal Web server
A portal Web server pushes the authentication page to users during portal authentication. It is also the
Web server to which the device redirects user HTTP requests.
Perform this task to configure the following portal Web server parameters:
• URL of the portal Web server
• Parameters carried in the URL when the device redirects the URL to users
The device supports multiple portal Web servers.
To configure a portal Web server:
Step Command Remarks
1. Enter system view. system-view N/A
2. Create a portal Web server
and enter its view.
portal web-server server-name
By default, no portal Web server is
created.
3. Specify the URL of the portal
Web server.
url url-string By default, no URL is specified.
4. Configure the parameters to
be carried in the URL when the
device redirects it to users.
url-parameter param-name
{ original-url | source-address |
source-mac | value expression }
By default, no redirection URL
parameters are configured.
Enabling portal authentication on an interface
You must first enable portal authentication on an access interface before it can perform portal
authentication for connected clients.
When a portal-enabled interface receives a portal packet, it checks the source IP address of the packet.
If the packet matches a locally configured portal authentication server, the interface regards the packet
valid and sends an authentication response packet to the portal authentication server. Otherwise, the
interface drops the packet. After a user logs in to the device, the user interacts with the portal
authentication server as needed.
Configuration restrictions and guidelines
When you enable portal authentication on an interface, follow these restrictions and guidelines:
• Make sure the interface has a valid IP address before you enable portal authentication on the
interface.
