Chapter 8 Establishing Cisco Secure ACS System Configuration
Step 5 To have the primary Cisco Secure ACS server send replication components to its
secondary Cisco Secure ACS servers at regular intervals, under Replication
Scheduling, select the Every X minutes option and in the X box type the length
of the interval at which Cisco Secure ACS should perform replication.
Note
To schedule times at which the primary Cisco Secure ACS server sends its
Step 6
replication components to its secondary Cisco Secure ACS servers, follow these
steps:
a.
b.
Tip Clicking times of day on the graph selects those times; clicking again clears
them. At any time you can click Clear All to clear all hours, or you can click
Set All to select all hours.
Step 7 To have the primary Cisco Secure ACS server send replication components
immediately upon receiving replication components from another
Cisco Secure ACS server, select the Automatically triggered cascade option.
Note
78-13751-01, Version 3.0
Because Cisco Secure ACS is momentarily shut down during
replication, a short replication interval may cause frequent failover of
your AAA clients to other Cisco Secure ACS servers. If AAA clients
are not properly configured to failover to other Cisco Secure ACS
servers, the brief interruption in authentication service may prevent
users from authenticating.
Under Replication Scheduling, select the At specific times option.
In the day and hour graph, click the times at which you want
Cisco Secure ACS to perform replication.
If you specify the Automatically triggered cascade option, you must
configure another Cisco Secure ACS server to act as a primary
Cisco Secure ACS server to this server; otherwise, this
Cisco Secure ACS server never replicates to its secondary
Cisco Secure ACS servers.
