When you log into the FortiGate-6000 GUI or CLI by connecting to the IP address of the MGMT1 or MGMT2 interface, or through a console connection, you are logging into the FortiGate-6000 management board (part of the FortiGate-6000 management plane). The management board is the FortiGate-6000 config-sync primary (or master). All configuration changes must be made from the management board GUI or CLI. In an HA cluster, all configuration changes must be made from the management board of the primary FortiGate-6000. The management board synchronizes configuration changes to the FPCs and makes sure FPC configurations remain synchronized with the management board.
Once you have logged into the management board GUI or CLI and verified that the system is operating normally, you can view and change the configuration of your FortiGate-6000 just like any FortiGate.
For the FortiGate-6000 to operate normally, the configurations of the management board and all of the FPCs must be synchronized. You can use the information in the following sections to make sure that these configurations are synchronized
