 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
 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.
 VLAN Tag Enable
Enables the VLAN tagging for the PTP frames.
 VID
VLAN Identifier used for tagging the VLAN packets.
 PCP
Priority Code Point value used for PTP frames.
Clock current Data Set
Object
Description
 stpRm
Steps Removed : It is the number of PTP clocks traversed from the grandmaster
to the local slave clock.
 Offset from master
Time difference between the master clock and the local slave clock, measured in
ns.
