4.12.2.6 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.

Device Type Indicates the Type of the Clock Instance. There are five Device Types.
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.
2 Step Flag 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.
Local Prio Priority [1..255] used in the 8275.1 BMCA.
Protocol Transport protocol used by the PTP protocol engine
Ethernet PTP over Ethernet multicast
EthernetMixed PTP using a combination of Ethernet multicast and unicast
IPv4Multi PTP over IPv4 multicast
IPv4Mixed PTP using a combination of IPv4 multicast and unicast
IPv4Uni PTP over IPv4 unicast
IPv6Mixed PTP using a combination of IPv6 multicast and unicast. Currently,
this is supported for only One step E2E Transparent clock.
EthIPv4IPv6Combo PTP using any one of Ethernet, IPv4 or IPv6. This is
supported for only one step E2E Transparent clocks.
