Overview of Authentication and Authorization Methods

both tunnel and policy, also known as hybrid authentication mode. Refer to “Configuring Policy Maptable Response” on page 26‐52.

•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 26‐57.

•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 26‐68.

•Secure Shell (SSH) – provides secure Telnet. For details, refer to “Configuring Secure Shell (SSH)” on page 26‐80.

•IP Access Lists (ACLs) – permits or denies access to routing interfaces based on protocol and inbound and/or outbound IP address restrictions configured in access lists. For details, refer to “Configuring Access Lists” on page 26‐82.

•TACACS+ (Terminal Access Controller Access‐Control System Plus) – a security protocol developed by Cisco Systems that can be used as an alternative to the standard RADIUS security protocol (RFC 2865). TACACS+ runs over TCP and encrypts the body of each packet. Refer to Chapter 27, TACACS+ Configuration, for information about the commands used to configure TACACS+.

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 Networkssupports 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.

•To specify a management level (management access authentication): Enterasys:version=1:mgmt=level

where level indicates the management level, either ro, rw, or su.

•To specify both management level and policy profile: Enterasys:version=1:mgmt=level:policy=string
