Local Clock Current Time
Object Description
PTP Time Shows the actual PTP time with nanosecond resolution.
Clock Adjustment
Method
Shows the actual clock adjustment method. The method depends on the
available hardware.
Synchronize to System
Clock
Activate 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 Data Set
Object Description
Clock ID An internal instance id (0..3)
Device Type Indicates the Type of the Clock Instance. There are five Device Types.
 Ord-Bound - clock's Device Type is Ordinary-Boundary Clock.
 P2p Transp - clock's Device Type is Peer to Peer Transparent
Clock.
 E2e Transp - clock's Device Type is End to End Transparent
Clock.
 Master Only - clock's Device Type is Master Only.
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 It shows 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
