User Guide for Cisco Secure ACS for Windows Server

To configure distributed system features for a given Cisco Secure ACS, you must
first define the other AAA server(s). For example, all Cisco Secure ACSes
involved in replication, remote logging, authentication proxying, and RDBMS
synchronization must have AAA server configurations for each other; otherwise,
incoming communication from an unknown Cisco Secure ACS is ignored and the
distributed system feature will fail.
Tip If the AAA Servers table does not appear, click Interface Configuration, click
Advanced Options, and then select the Distributed System Settings check box.
This section contains the following topics:
• AAA Server Configuration Options, page 4-22
• Adding a AAA Server, page 4-24
• Editing a AAA Server, page 4-26
• Deleting a AAA Server, page 4-28
AAA Server Configuration Options
A AAA server configuration enables Cisco Secure ACS to interact with the AAA
server that the configuration represents. A AAA server that does not have a
corresponding configuration in Cisco Secure ACS, or whose configuration in
Cisco Secure ACS is incorrect, does not receive AAA services from Cisco Secure
ACS, such as proxied authentication requests, database replication
communication, remote logging, and RDBMS synchronization. Also, several
distributed systems features require that the other Cisco Secure ACSes included
in the distributed system be represented in the AAA Servers table. For more
information about distributed systems features, see
About Distributed Systems,
page 4-2 .
The Add AAA Server and AAA Server Setup pages include the following options:
• AAA Server Name—The name you assign to the AAA server configuration.
The AAA server hostname that is configured in Cisco Secure ACS does not
have to match the hostname configured on a network device. We recommend
that you adopt a descriptive, consistent naming convention for AAA server
names. Maximum length for a AAA server name is 32 characters.
