You can also use SNMP to manage the cluster by configuring a cluster interface for SNMP administrative access. Using an SNMP manager you can get cluster configuration information and receive traps.
Note: You cannot connect to the HA interfaces to manage the cluster or to manage individual
FortiGate units in the cluster.
You can change the cluster configuration by connecting to the cluster and changing the configuration of the primary FortiGate unit. The cluster automatically synchronizes all configuration changes to the subordinate units in the cluster as the changes are made.
The only configuration change that is not synchronized is the FortiGate host name. You can give each cluster unit a unique host name to help to identify cluster members. For information about changing the host name of cluster members, see “Changing cluster unit host names” on page 84.
You can use the
You can manage individual cluster units by using SSH to connect to the CLI of the cluster. From the CLI you can use the execute ha manage command to connect to the CLI of each unit in the cluster. You can also manage individual cluster units by using a

Configuring cluster interface monitoring
Monitor FortiGate interfaces to make sure that they are functioning properly and that they are connected to their networks. If a monitored interface fails or is disconnected from its network, the FortiGate unit stops processing traffic and is removed from the cluster. If you can
