Reports this clock's estimate of its parent clock's phase drift rate, i.e. how fast the parent's clock is observed to be drifting.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.248.11.50.1.4.2.1.16
snmpwalk -v2c -c public <target> HM2-TIMESYNC-MIB::hm2Ptp2ObservedParentClockPhaseChangeRate

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.248.11.50.1.4.2.1.16.1
snmpget -v2c -c public <target> HM2-TIMESYNC-MIB::hm2Ptp2ObservedParentClockPhaseChangeRate.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> hm2Ptp2ObservedParentClockPhaseChangeRate.1
