Description	This article describes how to configure interface speed on FortiGate as it can't be configured on FortiManager.
Scope	FortiManager, FortiGate.

To solve this issue, we can apply either of the below: Configure interface speed on the FortiGate side. FortiManager can keep this config in the DB from auto update or after retrieval, but will not install it. Apply a script run on a remote device, then auto-update the FortiManager device DB.
