ieee8021AsPortDSDelayAsymmetryHs
Module: IEEE8021-AS-MIB
OID (symbolic): IEEE8021-AS-MIB::ieee8021AsPortDSDelayAsymmetryHs
OID (numeric): 1.3.111.2.802.1.1.20.1.5.1.15
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: The most (highest) significant 32 bits, signed 96 bit number in 2**-16 ns. The value is the asymmetry in the propagation delay on the link attached to this port relative to the grandmaster time base, as defined in 8.3. If propagation delay asymmetry is not modeled, then delayAsymmetry is 0.
This object MUST be read or written at the same time as ieee8021AsPortDSDelayAsymmetryMs, and ieee8021AsPortDSDelayAsymmetryLs, which represents middle and least significant 32 bits of values, respectively, in order for the read or write operation to succeed.
The contents of this variable SHALL be maintained across a restart of the system.
What is ieee8021AsPortDSDelayAsymmetryHs?
Most significant 32 bits of the configured link delay asymmetry correction applied relative to the grandmaster time base; zero if asymmetry isn't modeled. Combine with the Ms and Ls objects, and adjust this on links with known unequal transmit/receive delays, e.g. certain optical paths.
