Initializing
Initializing 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.
Faulty
Faulty 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.
Disabled
Disabled 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.
Listening
Listening 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.
PreMaster
PreMaster 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.
Master
Master The port is behaving as a master port.
Passive
Passive 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.
Uncalibrated
Uncalibrated 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.
Slave
Slave The port is synchronizing to the selected master
port.
GrandMaster
GrandMaster The port is in the Grand Master state (i.e. has
the best clock). The device can become
GrandMaster only if the PTP Mode=Automatic
and there's another device on the network that
was Master.
Error
Error One or more ports have an error state.
