tnPtpDConstant
Module: TN-PTP-MIB
OID (symbolic): TN-PTP-MIB::tnPtpDConstant
OID (numeric): 1.3.6.1.4.1.868.2.5.123.1.5.1.16
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The default clock servo uses a PID regulator to calculate the current clock rate. i.e. clockAdjustment = OffsetFromMaster/ P constant + Integral(OffsetFromMaster)/ I constant + Differential OffsetFromMaster)/ D constant [1..10000].
What is tnPtpDConstant?
The Derivative constant (1-10000) in the servo's PID formula, governing how strongly the rate of change of offset feeds into the current clock-rate adjustment.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.868.2.5.123.1.5.1.16 snmpwalk -v2c -c public <target> TN-PTP-MIB::tnPtpDConstant
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.868.2.5.123.1.5.1.16.1 snmpget -v2c -c public <target> TN-PTP-MIB::tnPtpDConstant.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.868.2.5.123.1.5.1.16.1 i <value>
