Advanced configuration 279 Managing node clusters Security does not synchronize incidents and events. Each node maintains this information separately. Automatic synchronization Synchronization occurs automatically at a random interval so that the nodes in a cluster do not expect updates at the same time. When you edit the master node or the network topology, your changes are automatically synchronized across all nodes in the cluster. Because automatic synchronization occurs randomly, rather than immediately, you may want to initiate an immediate synchronization using Force Database Sync. See "Forcing nodes to synchronize" on page 83. Reapplying policy assignments after setting cluster master This section describes setting protection policies to an interface and applying them to multiple interfaces. In a cluster, the master node stores the definitions of protection policies that you apply to slave nodes. If the master node fails or is demoted by setting a new cluster master, the link is broken between applied policies and their definitions. Slave nodes sometimes then appear to have viable policies applied that in reality are disabled. Prevent losing policies through failure by backing up the master node. Prevent losing policies when demoting by reapplying policy definitions to the new master node. Note: SuperUsers can reapply policies to an interface; Administrators, StandardUsers, and RestrictedUsers cannot. See "User groups reference" on page 319 for more about permissions. See "Backing up and restoring" on page 297. See "Setting policies to interfaces" on page 115. Forcing synchronization All software and appliance nodes synchronize with the master node. The Network Security console provides a way to trigger synchronization by restarting or rebooting slave nodes, or by forcing. To force databases to synchronize at any time ◆ In the Network Security console, click Admin > Force Database Sync, and click OK.
