Web and MAC Authentication

Configuring MAC Authentication on the Switch

Using the Restrictive-Filter Option

The restrictive-filter option allows the switch to reply to all HTTP requests to

the switch’s IP address with an HTTP-redirect containing the URL of the

registration server. It is used when there is no registration process and only a

warning or informational page is displayed to the client.

If SSL is not configured, the switch verifies that the MAC address and interface

port parameters are present. If SSL is enabled, the switch ensures that the

HTTP request is to the registration server’s destination IP address.
