• 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
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
