The clock may be set up in either normal or unicast mode. In unicast mode the
clock must be explicitly told whether it is a master or a slave, and the clock
must never change away from this setup automatically.

The check box is enabled when the interface bit rate is 10 Gbps or less.
Select this check box to start the clock. The settings of the Slave modeSlave mode and
UnicastUnicast check boxes in Setup tab will determine whether the clock runs as a
slave or will become the grandmaster clock.
When the Network Master becomes a grandmaster, and if the internal clock is selected
(or if the GPS is not available), the IEEE 1588 clock is set from the Network Master's
internal time (offset by the selected UTC offset). This action only takes place when the
clock is restarted (e.g. disable/enable the clock will force this).
When the Network Master is grandmaster in unicast mode, only one slave will be
accepted at a time. Other slaves are just ignored.
Ext. LogExt. Log
Used to record the external log. If you select this, the IEEE1588v2 LogIEEE1588v2 Log button
appears in the navigation area of Test Result.
CaptureCapture
Used to capture the packets concerning IEEE 1588 v2 protocol. The captured
packet data are saved to file with extension "pcap" when the measurement has
ended. The destination folder of the captured data file is the same folder where
the measurement result file is saved.
When capturing the packets concerning IEEE 1588v2 protocol, FCS values of Ethernet
frames are not included in the captured packet data file.
FollowsFollows
It is possible to let the Port 2 copy the setup from Port 1 by touching the
FollowFollow button. When this button is displayed in green, Port 2 continues to
follow Port 1 change. This button appears when the Port 1 settings can be copy
to Port 2.
