CiscoSecure Database Replication
– Manually—Cisco Secure ACS does not perform automatic database
replication.
– Automatically Triggered Cascade—Cisco Secure ACS performs
database replication to the configured list of secondary Cisco Secure
ACSes when database replication from a primary Cisco Secure ACS
completes. This enables you to build a propagation hierarchy of
Cisco Secure ACS, relieving a primary Cisco Secure ACS from the
burden of propagating the replicated components to every other
Cisco Secure ACS. For an illustration of cascade replication, see
Figure 9-1 .
Note If you intend to use cascading replication to replicate network
configuration device tables, you must configure the primary
Cisco Secure ACS with all Cisco Secure ACSes that will receive
replicated database components, regardless of whether they receive
replication directly or indirectly from the primary Cisco Secure ACS.
For example, if the primary Cisco Secure ACS replicates to two
secondary Cisco Secure ACSes which, in turn, each replicate to two
more Cisco Secure ACSes, the primary Cisco Secure ACS must have
AAA server configurations for all six Cisco Secure ACSes that will
receive replicated database components.
– 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.
