Web and MAC Authentication
Setup Procedure for Web/MAC Authentication
Note that when configuring a RADIUS server to assign a VLAN, you can
use either the VLAN’s name or VID. For example, if a VLAN configured in
the switch has a VID of 100 and is named vlan100, you could configure the
RADIUS server to use either “100” or “vlan100” to specify the VLAN.
4. Determine whether to use the optional “Unauthorized VLAN” mode for
clients that the RADIUS server does not authenticate. This VLAN must be
statically configured on the switch. If you do not configure an “Unautho-
rized VLAN”, the switch simply blocks access to unauthenticated clients
trying to use the port.
5. Determine the authentication policy you want on the RADIUS server and
configure the server. Refer to the documentation provided with your
RADIUS application and include the following in the policy for each client
or client device:
• The CHAP-RADIUS authentication method.
• An encryption key
• One of the following:
– If you are configuring Web-based authentication, include the user
name and password for each authorized client.
– If you are configuring MAC-based authentication, enter the
device MAC address in both the username and password fields of
the RADIUS policy configuration for that device. Also, if you want
to allow a particular device to receive authentication only
through a designated port and switch, include this in your policy.
6. Determine the IP address of the RADIUS server(s) you will use to support
Web- or MAC-based authentication. (For information on configuring the
switch to access RADIUS servers, refer to “Configuring the Switch To
Access a RADIUS Server” on page 3-28.)
7. (Optional) For enhanced web authentication, determine the IP address or
host name of the web servers used to store and display customized login
web pages, and the page path on the server where the HTML files (includ-
ing all graphics and HTML frames) used for the login pages are stored.
• Create the customized web pages as described in “Using Customized
Login Web Pages for Enhanced Web Authentication” on page 3-17.
• If necessary, configure the DNS server required to resolve the host
name to its target IP address. For more information, see the “Diagnos-
tic Tools” section in the Troubleshooting chapter of the Management
and Configuration Guide.
