Module: HH3C-DOT3-EFM-EPON-MIB
OID (symbolic): HH3C-DOT3-EFM-EPON-MIB::hh3cDot3MpcpRoundTripTime
OID (numeric): 1.3.6.1.4.1.25506.2.42.2.1.1.1.1.9
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: A read-only value that reports the MPCP round trip time in increments of Time Quanta (TQ) 16ns. The value returned shall be (round trip time in ns)/16. If this value exceeds (2^16-1) the value (2^16-1) shall be returned. This attribute is relevant for an OLT and an ONU. For the OLT there is a value per LLID
What is hh3cDot3MpcpRoundTripTime?
A read-only value, in 16ns Time Quanta units (capped at 2^16-1), reporting the measured MPCP round-trip time between an OLT and its ONU on this LLID, used for ranging in the PON's time-division access scheme. Admins can watch this for unusually high round-trip values that indicate a fiber distance or ranging problem on that subscriber link.
