V7122 Gateway User Guide

To set up a RADIUS server:
1
Define the gateway as an authorized client of the RADIUS server, with a predefined
‘shared secret’ (a password used to secure communication) and a vendor ID. Figure 121
displays an example of the file clients.conf (FreeRADIUS client configuration).
Figure 113
Example of the File clients.conf (FreeRADIUS Client Configuration)
#
# clients.conf - client configuration directives
#
client 10.31.4.47 {
secret = FutureRADIUS
shortname = tp1610_master_tpm
}
2
If access levels are required, set up a VSA dictionary for the RADIUS server and select
an attribute ID that represents each user's access level. The following example shows a
dictionary file for FreeRADIUS that defines the attribute ‘ACL-Auth-Level’ with ID=35.
Figure 114
Example of a Dictionary File for FreeRADIUS (FreeRADIUS Client Configuration)
#
# 3Com VSA dictionary
#
VENDOR 3Com 5003
ATTRIBUTE ACL-Auth-Level 35 integer 3Com
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
In the RADIUS server, define the list of users authorized to use the gateway, using one
of the password authentication methods supported by the server implementation. The
following example shows a user configuration file for FreeRADIUS using a plain-text
password.
Figure 115
Example of a User Configuration File for FreeRADIUS Using a Plain-Text Password
# users - local user configuration database
john Auth-Type := Local, User-Password == "qwerty"
Service-Type = Login-User,
ACL-Auth-Level = ACL-Auth-SecurityAdminLevel
larry Auth-Type := Local, User-Password == "123456"
Service-Type = Login-User,
ACL-Auth-Level = ACL-Auth-UserLevel
4
Record and retain the IP address, port number, ’shared secret’, vendor ID and VSA
access level identifier (if access levels are used) used by the RADIUS server.
