Configuring AAA Servers

Deleting AAA Clients

To delete AAA clients:
Step 1 In the navigation bar, click Network Configuration.
The Network Configuration page opens.
Step 2 Do one of the following:
•If you are using NDGs, click the name of the NDG to which the AAA client is assigned. Then, click
the AAA client hostname in the AAA Clients table.
•To delete AAA clients when you have not enabled NDGs, click the AAA client hostname in the
AAA Clients table.
The AAA Client Setup for the Name page appears.
Step 3 To delete the AAA client and have the deletion take effect immediately, click Delete + Apply.
Note Restarting ACS services clears the Logged-in User report and temporarily interrupts all ACS
services. As an alternative to restarting when you delete AAA clients, you can click Delete.
However,when you do, the change does not take effect until you restart the system, which you
can do by choosing System Configuration > Service Control. Then, chooseRestart.
A confirmation dialog box appears.
Step 4 Click OK.
ACS restarts AAA services and the AAA client is deleted.
If you have a configuredRADIUS/TACACS source-interface command on the AAA client, ensure that
you configure the client on ACS by using the IP address of the interface that is specified.
Configuring AAA Servers
This section presents procedures for configuringAAA servers in the ACS web interface. For additional
information about AAA servers, see AAA Servers in Distributed Systems, page 3-2.
Toconfigure distributed system features for a given ACS, you must firstdefine the other AAA server(s).
For example, all ACSs that are involved in replication, remote logging, authentication proxying, and
RDBMS synchronization must have AAA server configurations for each other; otherwise, incoming
communication from an unknown ACS is ignored and the distributed system feature will fail.
Tip If the AAA Servers table does not appear,choose Interface Configuration > Advanced Options. Then,
check the Distributed System Settings check box.
