Basic Deployment Factors for Cisco Secure ACS
In the small LAN environment, see Figure 2-1, network architects typically place
a single Cisco Secure ACS internal to the AAA client, protected from outside
access by a firewall and the AAA client. In this environment, the user database is
usually small, there are few devices that require access to the Cisco Secure ACS
for AAA, and any database replication is limited to a secondary Cisco Secure
ACS as a backup.
Figure 2-1 Small Dial-up Network
In a larger dial-in environment, a single Cisco Secure ACS with a backup may be
suitable, too. The suitability of this configuration depends on network and server
access latency. Figure 2-2 shows an example of a large dial-in arrangement. In this
scenario the addition of a backup Cisco Secure ACS is a recommended addition.
