Establishing Cisco Secure ACS System Configuration

With regard to database replication, we make the following distinctions about

Cisco Secure ACSes:

A Cisco Secure ACS can be both a primary Cisco Secure ACS and a secondary

Cisco Secure ACS, provided that it is not configured to be a secondary

Cisco Secure ACS to a Cisco Secure ACS for which it performs as a primary

Cisco Secure ACS.

Bidirectional replication, wherein an Cisco Secure ACS both sends database

components to and receives database components from the same remote

Cisco Secure ACS, is not supported. Replication fails if an Cisco Secure ACS is

configured to replicate to and from the same Cisco Secure ACS.

All Cisco Secure ACSes involved in replication must run the same release of the

Cisco Secure ACS software. For example, if the primary Cisco Secure ACS is

running Cisco Secure ACS version 3.0, all secondary Cisco Secure ACSes should

be running Cisco Secure ACS version 3.0. Because patch releases can introduce

significant changes to the CiscoSecure database, we strongly recommend that

Cisco Secure ACSes involved in replication use the same patch level, too.

Primary Cisco Secure ACS—A Cisco Secure ACS that sends replicated

CiscoSecure database components to other Cisco Secure ACSes.

Secondary Cisco Secure ACS—A Cisco Secure ACS that receives

replicated CiscoSecure database components from a primary

Cisco Secure ACS. In the HTML interface, these are identified as replication
