Description
An internal instance id (0..3)
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
Static member: defined by the system, true if two-step Sync events and Pdelay_Resp
events are used
The total number of physical ports in the node
It shows unique clock identifier
Clock domain [0..127].
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).
Clock priority 1 [0..255] used by the BMC master select algorithm.
Clock priority 2 [0..255] used by the BMC master select algorithm.
Transport protocol used by the PTP protocol engine
ethernet PTP over Ethernet multicast
ip4multi PTP over IPv4 multicast
ip4uni PTP over IPv4 unicast
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.
Enables the VLAN tagging for the PTP frames.
VLAN Identifier used for tagging the VLAN packets.
Priority Code Point value used for PTP frames.
Description
Steps Removed : It is the number of PTP clocks traversed from the grandmaster to the
local slave clock.
Time difference between the master clock and the local slave clock, measured in ns.
The mean propagation time for the link between the master and the local slave
