attributes containing configuration information. If the server rejects the user, it returns a negative result. If the server rejects the client or the shared “secrets” differ, the server returns no result. If the server requires additional verification from the user, it returns a challenge, and the request process begins again.

If you use a RADIUS server to authenticate users, you must configure user attributes in the user database on the RADIUS server. The user attributes include the user name, password, and privilege level.

NOTE: To set the privilege level, use the Service-Typeattribute. Do not us any vendor-specific attribute value pairs.

The following example shows an entry in the FreeRADIUS /etc/raddb/users file that allows a user (name: admin) to log onto the switch with read/write privileges, which is equivalent to privilege level 15.

admin

Auth-Type :=

Local,

 

User-Password == "pass1234"

 

Service-Type = NAS-Prompt-User

enable

Auth-Type := Local,

 

User-Password == "pass5678"

 

Service-Type = Administrative-User

The values for the Service-Type attribute are as follows:

NAS-Prompt-Userindicates the user should be provided a command prompt on the NAS, from which nonprivileged commands can be executed.

Administrative-Userindicates the user should be granted access to the administrative interface to the NAS, from which privileged commands can be executed.

RADIUS Configuration Examples

This section contains examples of commands used to configure RADIUS settings on the switch.

Example #1: Basic RADIUS Server Configuration

This example configures two RADIUS servers at 10.10.10.10 and 11.11.11.11. Each server has a unique shared secret key. The shared secrets are configured to be secret1 and secret2 respectively. The server at

10.10.10.10is configured as the primary server. The process creates a new authentication list, called radiusList, which uses RADIUS as the primary authentication method, and local authentication as a backup method in the event that the RADIUS server cannot be contacted.
