Specifies dynamically the current PTP state of the device.
(ref: IEEE Std 1588-2008)
The port initializes its data sets, hardware, and
communication facilities. No port of the clock shall place any
PTP messages on its communication path. If one port of a
boundary clock is in the INITIALIZING state, then all ports
shall be in the INITIALIZING state.
The fault state of the protocol. A port in this state shall not
place any PTP messages except for management messages
that are a required response to another management
message on its communication path. In a boundary clock,
no activity on a faulty port shall affect the other ports of the
device. If fault activity on a port in this state cannot be
confined to the faulty port, then all ports shall be in the
FAULTY state.
The port shall not place any messages on its communication
path. In a boundary clock, no activity at the port shall be
allowed to affect the activity at any other port of the
boundary clock. A port in this state shall discard all PTP
received messages except for management messages.
The port is waiting for the announceReceiptTimeout to
expire or to receive an Announce message from a master.
The purpose of this state is to allow orderly addition of
clocks to a domain. A port in this state shall not place any
PTP messages on its communication path except for
Pdelay_Req, Pdelay_Resp, Pdelay_Resp_Follow_Up, or
signaling messages, or management messages that are a
required response to another management message.
The port shall behave in all respects as though it were in
the MASTER state except that it shall not place any
messages on its communication path except for
Pdelay_Req, Pdelay_Resp, Pdelay_Resp_Follow_Up,
signaling, or management messages.
The port is behaving as a master port.
The port shall not place any messages on its communication
path except for Pdelay_Req, Pdelay_Resp,
Pdelay_Resp_Follow_Up, or signaling messages, or
management messages that are a required response to
another management message.
One or more master ports have been detected in the
domain. The appropriate master port has been selected,
and the local port is preparing to synchronize to the
selected master port. This is a transient state to allow
initialization of synchronization servos, updating of data
sets when a new master port has been selected, and other
implementation-specific activity.
The port is synchronizing to the selected master port.
The port is in the GrandMaster state (i.e. has the best
clock). The camera can become GrandMaster only if the PTP
Mode=Automatic and there's another device on the network
that was Master.
One or more ports have an error state.
Specifies the IEEE1588 servo status.
The servo is not yet ready to track the master clock.
The servo is unlocked and synchronizing to the master
clock.
The servo is adjusting (synchronizing) to the master clock.
The servo state is currently not applicable.
Port identity of the current best master. The clock ID is an
Extended Unique Identifier (EUI)-64 64-bit ID, converted
from the 48-bit MAC address, by inserting 0xfffe at the
m iddle of the MAC address.
Dynam ically returns the 64-bit value of the PTP offset with
the m aster. This value is the input for clock corrections for
the slave device clock servo algorithms.
