Clock Default Data Set
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.

• Device Type
• One-Way
• 2 Step Flag
• Ports
• Clock Identity
• Dom
• Clock Quality

• Protocol
Description
Indicates the Type of the Clock Instance. There are five Device Types.

P2p Transp - clock's Device Type is Peer to Peer Transparent Clock.

E2e Transp - clock's Device Type is End to End Transparent Clock.
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.
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.
Priority [1..255] used in the 8275.1 BMCA.
