docsRphyPtpCcapParentDataSetPhaseChangeRate
Module: DOCS-RPHY-PTP-MIB
OID (symbolic): DOCS-RPHY-PTP-MIB::docsRphyPtpCcapParentDataSetPhaseChangeRate
OID (numeric): 1.3.6.1.4.1.4491.2.1.32.1.2.3.5
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: This attribute represents the value of Phase Change Rate, which is an estimate of the parent clock's phase change rate as observed by the slave clock. If the estimate exceeds the capacity of its data type, this value is set to 0x7FFF FFFF. A positive sign indicates that the parent clock's phase change rate is greater than the rate of the slave clock. The computation of this value is optional, but if not computed,the value of parentStats is FALSE.
What is docsRphyPtpCcapParentDataSetPhaseChangeRate?
This OID reports the estimated phase change rate of the parent clock as observed by this slave CCAP, in nanoseconds, saturating at 0x7FFFFFFF if it overflows, with a positive value meaning the parent's rate exceeds the slave's; like ClockOffset, it's only meaningful when ParentStats is true. Admins check it when diagnosing why timing appears to be drifting relative to the parent clock.
