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.
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
VID
VLAN Identifier used for tagging the VLAN packets.
PCP
Priority Code Point value used for PTP frames.
DSCP
DSCP value used when transmitting IPv4 encapsulated packets
Clock Time Properties Data Set
The clock time properties data set is defined in the IEEE 1588 Standard. The data set is both configurable and dynamic, i.e.
the parameters can be configured for a grandmaster. In a slave clock the parameters are overwritten by the grandmasters
timing properties. The parameters are not used in the current PTP implementation.
The valid values for the Time Source parameter are:
■ 16 (0x10) ATOMIC_CLOCK
■ 32 (0x20) GPS
■ 48 (0x30) TERRESTRIAL_RADIO
■ 64 (0x40) PTP
■ 80 (0x50) NTP
■ 96 (0x60) HAND_SET
■ 144 (0x90) OTHER
■ 160 (0xA0) INTERNAL_OSCILLATOR
