Chapter 8 Establishing Cisco Secure ACS System Configuration
CiscoSecure Database Replication
from the burden of propagating the replicated components to every other
Cisco Secure ACS. For an illustration of cascade replication, see
Figure 8-1
.
–
Every X minutes—Cisco Secure ACS performs, on a set frequency,
database replication to the configured list of secondary
Cisco Secure ACSes. The unit of measurement is minutes, with a default
update frequency of 60 minutes.
–
At specific times...—Cisco Secure ACS performs, at the time specified
in the day and hour graph, database replication to the configured list of
secondary Cisco Secure ACSes. The minimum interval is one hour, and
the replication takes place on the hour selected.
•
Partner Options—You can specify the secondary Cisco Secure ACSes for
this primary Cisco Secure ACS. The options that control the secondary
Cisco Secure ACSes to which a primary Cisco Secure ACS replicates appear
in the Partners section of the Outbound Replication table.
Note
The items in the AAA Server and Replication lists reflect the AAA
servers configured in the AAA Servers table in Network Configuration.
To make a particular Cisco Secure ACS available as a secondary
Cisco Secure ACS, you must first add that Cisco Secure ACS to the AAA
Servers table of the primary Cisco Secure ACS.
–
AAA Server—This list represents the secondary Cisco Secure ACSes
that this primary Cisco Secure ACS does not send replicated components
to.
–
Replication—This list represents the secondary Cisco Secure ACSes
that this primary Cisco Secure ACS does send replicated components to.
Note
Cisco Secure ACS does not support bidirectional database replication. A
secondary Cisco Secure ACS receiving replicated components verifies that the
primary Cisco Secure ACS is not on its Replication list. If not, the secondary
Cisco Secure ACS accepts the replicated components. If so, it rejects the
components.
