The HA sync frequency for A-A or A-P FortiAuthenticator Cluster is 4 seconds.
This can be analyzed by following the steps below:
1) Upload the debug kit provided by TAC.
2) connect to the FortiAuthenticator via SSH and run the following commands:
# get system status <----- Check the HA status.
shell
haop shmview
When haop shmview is run multiple times, the value to the extreme right goes up to 4 seconds and then starts again. This confirms that the HA replication frequency is 4 seconds.
The following logs are for an A-A cluster:
Load Balancer status:
Primary node status:
