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.
