Pdelay_Resp events are used.
Clock Identity It shows unique clock identifier.
One Way If true, one-way measurements are used. This parameter applies only to a slave.
In one-way mode no delay measurements are performed, i.e. this is applicable
only if frequency synchronization is needed. The master always responds to
delay requests.
Protocol Transport protocol used by the PTP protocol engine
ethernet PTP over Ethernet multicast
ip4multi PTP over IPv4 multicast
ip4uni PTP over IPv4 unicast
Note : IPv4 unicast protocol only works in Master only and Slave only clocks
See parameter Device Type
In a unicast Slave only clock you also need configure which master clocks
to request Announce and Sync messages from. See: Unicast Slave configuration
VLAN Tag Enable Enables the VLAN tagging for the PTP frames.
Note: Packets are only tagged if the port is configured for VLAN tagging.
i.e:
Port Type! = Unaware and Port VLAN mode == None, and the port is member of
the VLAN.
VID VLAN Identifier used for tagging the PTP frames.
PCP Priority Code Point value used for PTP frames.
