Cisco Systems Servers Manuale Utente

To add and configure a AAA server, follow these steps:

In the navigation bar, click Network Configuration.

Result: The Network Configuration section opens.

Do one of the following:

If you are using NDGs, click the name of the NDG to which the AAA server 
is to be assigned. Then, click Add Entry below the [name] AAA Servers 
table.

To add a AAA server when you have not enabled NDGs, below the AAA 
Servers table, click Add Entry.

Result: The Add AAA Server page appears.

If this is a new AAA Server, in the AAA Server Name box, type a name for the 
remote AAA server.

In the AAA Server IP Address box, type the IP address assigned to the remote 
AAA server.

In the Key box, type the shared secret that the remote AAA server and the 
Cisco Secure ACS use to encrypt the data.

The key is case sensitive. If the keys between the two AAA servers are 
not identical when authentication is forwarded, the request is 
incorrectly encrypted and authentication fails.

From the Network Device Group list, select the NDG to which this AAA Server 
belongs.

To enable NDGs, click Interface Configuration, click Advanced 
Options, and then click Network Device Groups.

To enable Watchdog packets, select the Log Update/Watchdog Packets from 
this remote AAA Server check box. Watchdog packets are interim packets sent 
periodically during a session. They serve to enable an approximation of session 
length in the event that no stop packet is received to mark the end of the session.
