Not a ptp state. This is an interface status indicated by Dante Controller.

Startup

Initializing

Faulty

There is an issue with the port and the port will try to initialize again after a timeout. The cycle repeats until the port initializes or user changes the port.

Disabled

Port is disabled by user or the network interface is down

Listening

Unable to sync with a leader clock. See Mac OSX shows ‘Listening’ under the Clock Status tab in Dante Controller | Audinate | FAQs if this is an OSX computer.

PreLeader

A transit state before switching to Leader state with a random timeout. Port in this state does not send sync messages. The random timeout allows only one device to remain in Leader state. This is the device with shorter timeout interval. Ports of the remaining devices will jump back to Follower or Passive states after jumping to Leader state. (imagine an existing Leader going away from the network and all the remaining devices competing to become Leader)

Leader

Device is the leader clock for the network, or unable to communicate with other Dante devices on the same network.

Passive

Port is a back-up “Follower” port as another port of the device is in Follower state.

Uncalibrated

Not used.

Follower

Device is synchronized to a clock leader

Standby

For unicast clocking across subnets or VLANs: Back-up unicast port as another device in same subnet has unicast port in Follower state.
