ieee8021AsCurrentDSOffsetFromMasterHs
Module: IEEE8021-AS-MIB
OID (symbolic): IEEE8021-AS-MIB::ieee8021AsCurrentDSOffsetFromMasterHs
OID (numeric): 1.3.111.2.802.1.1.20.1.2.2
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The most significant 32 bits of the offset, signed 96 bit number in 2**-16 ns, an implementation-specific computation of the current value of the time difference between a master and a slave as computed by the slave.
This object MUST be read at the same time as ieee8021AsCurrentDSOffsetFromMasterMs, and ieee8021AsCurrentDSOffsetFromMasterLs, which represents middle and least significant 32 bits of values, respectively, in order for the read operation to succeed.
What is ieee8021AsCurrentDSOffsetFromMasterHs?
The most significant 32 bits of a 96-bit signed value (in units of 2^-16 ns) representing this slave's current time offset from its master; must be read together with the Ms and Ls objects to reconstruct the full offset. Large or growing values across a poll interval flag a sync problem worth investigating.
