ports. For details on using CLI commands to configure 802.1X, refer to “
•
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
•
Multiple Authentication Methods – allows users to authenticate using multiple methods of
authentication on the same port. For details, refer to “
Configuring Multiple Authentication
•
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 “
•
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 “
•
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 “
•
Secure Shell (SSH) – provides secure Telnet. For details, refer to “
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
configured on the switch, the switch then dynamically applies the policy profile to the physical
port the user/device is authenticating on.
Filter-ID Attribute Formats
Enterasys Networks supports two Filter‐ID formats — “decorated” and “undecorated.” The
decorated format has three forms:
•
To specify the policy profile to assign to the authenticating user (network access
authentication):
Enterasys:version=1:policy=string
where string specifies the policy profile name. Policy profile names are case‐sensitive.
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.
