Description

This article describes how to fix the device registration status 'Unknown' error in multi Vdom mode.

Scope

FortiGate, FortiManager.

Solution

The TCP/541 is allowed between FortiGate and FortiManager but device registration is stuck in connection handshake with unknown status.

# diagnose fdsm central-mgmt-status
Connection status: Handshake
Registration status: Unknown

In this scenario, the FortiGate is operating in multi VDOM mode with a FortiManager Fabric connector that is created via GUI console. The system central-management will use 'root' as the default VDOM setting and Ensure the VDOM setting is set correctly with respect to the customer environment by using the CLI console.

# config system central-management
    set type fortimanager
    set fmg <fmg IP>
    set vdom "vdom name" <<<
    set fmg-source-ip <ip address>
    set interface-select-method specify
    set interface <interface name>
end
