Once the RADIUS server receives the request, it validates the RADIUS client that
sent the request. A request from a client for which the RADIUS server does not have
a shared secret is discarded. If the client is valid, the RADIUS server consults a
database of users to find the user whose name matches the request. The user entry
in the database contains the required elements for authentication including the
usename, password, access and management privileges.
Client-Server Security
Transactions between the client and server are authenticated through the use of a
shared secret, which is never sent over the network. In addition, any user passwords
are sent encrypted between the client and RADIUS server, to further secure account
passwords.
Radius Client Configuration Procedures
The following paragraphs describe the procedures to configure the RADIUS client
through the command line interface. The RADIUS client is a key-enabled feature and
is not available without a valid key. For more information on adding a key, see “Key
Enabled Features” on page 4-29.
For RADIUS client configuration via the WMI, see “User Lookup Configuration” on
page 8-22.
Secret Configuration
The RADIUS client is authenticated by a RADIUS server through a shared secret.
When configuring the shared secret:
• If multiple RADIUS Servers (a primary and secondary are supported) are
configured, one shared secret is required per server.
• On the command line the primary server is specified as ’1’ and the secondary
server is specified as ’2’. If the server is not specified, the command will, by
default, configure for the primary server.
• Only one shared secret (for primary or secondary server) can be set per
command.
• The shared secret’s composition is an ASCII string up to 64 characters.
• Secrets are never displayed in plain text format and are encrypted during
client-server transactions.
The following command will set the shared secret for the secondary server to noclues.
-> radius set secret 2 noclues
The following command displays the shared secret.
-> rad list secret
