Module: IEEE8021-AS-MIB
OID (symbolic): IEEE8021-AS-MIB::ieee8021AsParentDSGrandmasterOffsetScaledLogVariance
OID (numeric): 1.3.111.2.802.1.1.20.1.3.7
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: Clock Allan variance of the local clock expressed as a base-2 logarithm multiplied by a scale factor of 256. Hysteresis is applied requiring the underlying computed variance to move by at least 128 before a change is reported. A value of 65535 (0xFFFF) indicates value is too large to be represented or has not been computed. The default value is set to ieee8021AsDefaultDSOffsetScaledLogVariance.
What is ieee8021AsParentDSGrandmasterOffsetScaledLogVariance?
The scaled Allan variance of the current grandmaster's clock, indicating its short-term stability; 65535 means the value is unknown or too large. Mostly consumed internally by the best master clock algorithm rather than read directly.
