Netgear GSM7228PS - ProSAFE 28 ports Gigabit Ethernet L2 Managed Stackable Switch with PoE Guía De Administador

You can enable captive portal on all the physical ports on the switch. It is not supported for VLAN 
interfaces, loopback interfaces or logical interfaces. The captive portal feature uses 
MAC-aaddress based authentication and not port-based authentication. This means that all the 
clients connected to the captive portal interface must be authenticated before they can get 
access to the network.

Clients connecting to the captive portal interface have three states; unknown, unauthenticated, 
and authenticated. 

Unknown. In the unknown state, the captive portal does not redirect HTTP/S traffic to the 

switch, but instead asks the switch whether the client is authenticated or unauthenticated. 

Unathenticated. The captive portal directs the HTTP/S traffic to the switch so that the 

client can authenticate with the switch. 

Authenticated. After successful authentication, the client is placed in authenticated state. 

In this state, all the traffic emerging from the client is forwarded through the switch.

Captive Portal Configuration

This section introduces the objects that make up the captive portal and describes the 
interaction between the captive portal and the network administrator. It explains what 
configurations are visible to the network administrator and enumerates the events.

All the configurations included in this section are managed using the CLI, the Web Interface, 
and SNMP, with one exception; to customize the captive portal Web page, you must use the 
Web Interface.

The captive portal configuration provides the network administrator control over verification 
and authentication, assignment to interfaces, client sessions, and Web page customization.

You can create multiple captive portal configuration instances. Each captive portal 
configuration contains various flags and definitions used to control client access and content 
to customize the user verification Web page. A captive portal configuration can be applied to 
one or more interfaces. An interface can only be a physical port on the switch. Software 
release 8.0 and newer versions can contain up to 10 captive portal configurations.
