configurationSyncStateSummary

The configuration sync state for the firewall. This summarizes the Config settings in the SyncStates for this firewall status object.

When you create a firewall or update its configuration, for example by adding a rule group to its firewall policy, Network Firewall distributes the configuration changes to all Availability Zones that have subnets defined for the firewall. This summary indicates whether the configuration changes have been applied everywhere.

This status must be IN_SYNC for the firewall to be ready for use, but it doesn't indicate that the firewall is ready. The Status setting indicates firewall readiness. It's based on this setting and the readiness of the firewall endpoints to take traffic.
