ieee8021AsCurrentDSOffsetFromMasterHs
IEEE8021-AS-MIB ·
.1.3.111.2.802.1.1.20.1.2.2
Object
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.
