Radius Filter-Id Attribute And Dynamic Policy Profile Assignment - Enterasys D-Series Cli Reference Manual

Overview of Security Methods
on using CLI commands to configure 802.1X, refer to "Configuring 802.1X Authentication" on
page 17‐11.
• MAC Authentication – provides a mechanism for administrators to securely authenticate
source MAC addresses and grant appropriate access to end user devices communicating with
D‐Series ports. For details, refer to "Configuring MAC Authentication" on page 17‐21.
• Multiple Authentication Methods – allows users to authenticate using multiple methods of
authentication on the same port. For details, refer to "Configuring Multiple Authentication
Methods" on page 17‐33.
• Multi‐User Authentication – User + IP Phone. The User + IP Phone authentication feature
supports authentication and authorization of two devices, specifically a PC cascaded with an
IP phone, on a single port on the D2. The IP phone must authenticate using MAC or 802.1X
authentication, but the user may authenticate by any method. This feature allows both the
user's PC and IP phone to simultaneously authenticate on a single port and each receive a
unique level of network access. For details, refer to "Configuring Multi‐User Authentication
(User + IP phone)" on page 17‐33.
• RFC 3580 Tunnel Attributes provide a mechanism to contain an 802.1X authenticated or MAC
authenticated user to a VLAN regardless of the PVID. Refer to "Configuring VLAN
Authorization (RFC 3580)" on page 17‐45.
• MAC Locking – locks a port to one or more MAC addresses, preventing the use of
unauthorized devices and MAC spoofing on the port For details, refer to "Configuring MAC
Locking" on page 17‐51.
• Port Web Authentication (PWA) – passes all login information from the end station to a
RADIUS server for authentication before allowing a user to access the network . PWA is an
alternative to 802.1X and MAC authentication. For details, refer to "Configuring Port Web
Authentication (PWA)" on page 17‐62.
• Secure Shell (SSH) – provides secure Telnet. For details, refer to "Configuring Secure Shell
(SSH)" on page 17‐74.

RADIUS Filter-ID Attribute and Dynamic Policy Profile Assignment

If you configure an authentication method that requires communication with a RADIUS server,
you can use the RADIUS Filter‐ID attribute to dynamically assign a policy profile and/or
management level to authenticating users and/or devices.
The RADIUS Filter‐ID attribute is simply a string that is formatted in the RADIUS Access‐Accept
packet sent back from the RADIUS server to the switch during the authentication process.
Each user can be configured in the RADIUS server database with a RADIUS Filter‐ID attribute
that specifies the name of the policy profile and/or management level the user should be assigned
upon successful authentication. During the authentication process, when the RADIUS server
returns a RADIUS Access‐Accept message that includes a Filter‐ID matching a policy profile name
17-2 Security Configuration
Note: To configure EAP pass-through, which allows client authentication packets to be forwarded
through the switch to an upstream device, 802.1X authentication must be globally disabled with the
set dot1x command.
Notes: The D2 supports up to two authenticated users per port.
The D2 cannot simultaneously support Policy and RFC 3580 on the same port. If multiple users are
configured to use a port, and the D2 is then switched from "policy" mode to "tunnel" mode (RFC-
3580 VLAN to port mapping), the total number of users supported to use a port will be reset to one.
RFC-3580 VLAN authorization is not supported by PWA authentication.
