Setting Up A Third-Party Radius Server - AudioCodes Mediant 3000 User Manual

16.2.1 Setting Up a Third-Party RADIUS Server

The following procedure provides an example for setting up the third-party RADIUS sever,
FreeRADIUS, which can be downloaded from www.freeradius.org. Follow the instructions
on this Web site for installing and configuring the server. If you use a RADIUS server from
a different vendor, refer to its appropriate documentation.

To set up a third-party RADIUS server (e.g., FreeRADIUS):
1. Define the AudioCodes device as an authorized client of the RADIUS server, with the
following:
•
Predefined shared secret (password used to secure communication between the
device and the RADIUS server)
•
Vendor ID
Below is an example of the clients.conf file (FreeRADIUS client configuration):
#
# clients.conf - client configuration directives
#
client 10.31.4.47 {
}
2. If access levels are required, set up a Vendor-Specific Attributes (VSA) dictionary for
the RADIUS server and select an attribute ID that represents each user's access level.
The example below shows a dictionary file for FreeRADIUS that defines the attribute
"ACL-Auth-Level" with "ID=35". For the device's user access levels and their
corresponding numeric representation in RADIUS servers, see Configuring Web User
Accounts.
#
# AudioCodes VSA dictionary
#
VENDOR AudioCodes 5003
ATTRIBUTE ACL-Auth-Level 35 integer AudioCodes
VALUE ACL-Auth-Level ACL-Auth-UserLevel 50
VALUE ACL-Auth-Level ACL-Auth-AdminLevel 100
VALUE ACL-Auth-Level ACL-Auth-SecurityAdminLevel 200
3. Define the list of users authorized to use the device, using one of the password
authentication methods supported by the server implementation. The example below
shows a user configuration file for FreeRADIUS using a plain-text password:
# users - local user configuration database
john
sue
4. Record and retain the IP address, port number, shared secret code, vendor ID, and
VSA access level identifier (if access levels are implemented) used by the RADIUS
server.
