This view provides a convenient way of quickly scanning the network for clock information. The view is in
table format, with the following fields for each device, in columns from the left, as follows:
n
Device Name: The label currently associated with the device.
n
Sync: Indicates the clock sync status for the device. A green light indicates that the device is cur-
rently synced to (or is driving) the network clock. A red light indicates that the device is not currently
synced.
n
Mute: Indicates the mute status for the device. A red icon indicates that the device is currently muted
(usually due to loss of clock sync). No icon in the mute column means that the device is not muted
(audio should be flowing normally).
n
Clock Source: Indicates the clock source for the device. ‘Dante’ means that the device is deriving its
clock from the Dante network, or is acting as master clock (but not deriving its clock from an external
source). ‘External’ means that the device is deriving its clock from an external word clock source.
n
Primary Status: Indicates the state of the PTP clock for the primary network interface. Clock Status
values and their meanings are as follows:
o
Master: Device is PTP master on that network
o
Slave: Device is a PTP slave on that network
o
Passive: Device is not using clock synchronization information from this interface
o
Link Down: The interface is not connected to the network
o
Not Supported: Where the device is non redundant the second interface is Not Supported
o
Not Available: The device does not support clock status reporting
Note: Other transient clock states exist, which are not listed above.
n
Secondary Status: Indicates the state of the PTP clock for the secondary network interface of a
redundant device.
n
AES67 Status: Indicates the state of the PTPv2 clock for AES67-enabled devices. Possible states
are identical to those of Primary and Secondary Status.
n
Preferred Master: Checking 'Preferred Master' raises the priority of the device in the clock master
election. If only one device on the network has this box ticked this ensures that the selected device
becomes clock master. When multiple devices have their Preferred Master box ticked, the master
will be elected from within that group. This is a convenient method of controlling the group of devices
from which the master can be selected.
n
Enable Sync To External: When checked this will force the device to derive its local clock from the
external word clock source. This will also ensure that this Dante device becomes clock master. It is
not normal practice configure more than one device with an external clock source. In this case, the
user is assumed to have synchronized external word clock sources (e.g. house clock). Where a
device does not support slaving to an external Word Clock the value in this column will be N/A.
Master Clock
The Dante network clock master, also called the 'Grand Master', is displayed at all times in the center of
the toolbar of the Network View. This is the device that is providing the time sync source for all devices on
the network.
The clock master is chosen automatically through an election process, though there are user configurable
parameters that allow prioritization of some devices in the clock master election. Configuring a device to
have an external word clock source will force that device to become clock master. Checking the preferred
