Method
Synchronize to
System Clock
Click this button to synchronize the System Clock to PTP Time.
Ports
Configuration
Click to edit the port data set for the ports assigned to this clock instance.
Clock Default
Dataset
The clock default data set is defined in the IEEE 1588 Standard. It holds
three groups of data: the static members defined at clock creation time, the
Dynamic members defined by the system, and the configurable members
which can be set here.
ClockId An existing internal Clock instance ID (0-3).
Device Type
Indicates the Type of the Clock Instance. There are five Device Types.
1 . Ord-Bound - Clock's Device Type is Ordinary-Boundary Clock.
2 . P2p Transp - Clock's Device Type is Peer to Peer Transparent Clock.
3 . E2e Transp - Clock's Device Type is End to End Transparent Clock.
4 . Master Only - Clock's Device Type is Master Only.
5 . Slave Only - Clock's Device Type is Slave Only.
2 Step Flag
Static member: defined by the system, true if two-step Sync events and
Pdelay_Resp events are used.
Ports The total number of physical ports in the node.
Clock Identity Shows the unique clock identifier.
Dom
Clock domain [0..127].
Clock Quality
The clock quality is determined by the system, and holds 3 parts: Clock
Class, Clock Accuracy and OffsetScaledLog Variance as defined in
IEEE1588.The Clock Accuracy values are defined in IEEE1588 table 6
(Currently the clock Accuracy is set to 'Unknown' as default).
Pri1 Clock priority 1 [0..255] used by the BMC master select algorithm..
Pri2 Clock priority 2 [0..255] used by the BMC master select algorithm..
Protocol
Transport protocol used by the PTP protocol engine Ethernet PTP over
Ethernet multicast ip4multi PTP over IPv4 multicast ip4uni PTP over IPv4
unicast
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.
