PTP Clock Mode Descriptions
Auto mode allows the port to operate either in the server or client state depending on whether the GridTime 3000 is
synchronized or not. When the GridTime 3000 is in sync or in holdover, the port will be in the server or passive server
state, when the GridTime 3000 is out of sync the port will be in the client state.
In server only mode, the port will always either be in the server or passive server state depending on whether it has
won the BMCA or not.
In client only mode, the port will always be in the client or listening state depending on whether there is a PTP server
available to sync to.
