Chapter 3 Network Configuration
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, choose Restart.
A confirmation dialog box appears.
Step 4 Click OK.
ACS restarts AAA services and the AAA client is deleted.
If you have a configured RADIUS/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 configuring AAA servers in the ACS web interface. For additional
information about AAA servers, see AAA Servers in Distributed Systems, page 3-2.
To configure distributed system features for a given ACS, you must first define 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, chooseInterface Configuration > Advanced Options. Then,
check the Distributed System Settings check box.
