ieee8021AsPortDSNdownMs
Module: IEEE8021-AS-MIB
OID (symbolic): IEEE8021-AS-MIB::ieee8021AsPortDSNdownMs
OID (numeric): 1.3.111.2.802.1.1.20.1.5.1.34
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: The least significant 32 bits, of unsigned 64 bit fixed point number between 0 and less than 2. For an OLT port of an IEEE 802.3 EPON link, the value is the effective index of refraction for the EPON downstream wavelength light of the optical path (see 13.1.4 and 13.8.1.2.2). The default value is 1.46805 for 1 Gb/s downstream links, and 1.46851 for 10 Gb/s downstream links.
For all other ports, the value is 0.
This object MUST be read or written at the same time as ieee8021AsPortDSNdownLs, which represents the least significant 32 bits of the value 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 ieee8021AsPortDSNdownMs?
Most significant 32 bits of the effective index of refraction for the EPON downstream wavelength on this port (0 on non-EPON ports, roughly 1.46805 for 1Gb/s, 1.46851 for 10Gb/s downstream); combine with the Ls object. Only meaningful on ports terminating an EPON link, for correcting downstream optical delay measurements.
