rttMonLatestJitterOperRTTSum2
Module: CISCO-RTTMON-MIB
OID (symbolic): CISCO-RTTMON-MIB::rttMonLatestJitterOperRTTSum2
OID (numeric): 1.3.6.1.4.1.9.9.42.1.5.2.1.3
Node type: OBJECT-TYPE
Type: Gauge32
Access: read-only
Description: The sum of squares of RTT's that are successfully measured (low order 32 bits). The high order 32 bits are stored in rttMonLatestJitterOperRTTSum2High.
What is rttMonLatestJitterOperRTTSum2?
This 32-bit gauge stores the lower portion of the sum-of-squares of round-trip times for successfully measured RTT probes in jitter monitoring. Combined with the high-order 32-bit value, it calculates variance and jitter metrics for voice and video quality assessment. An operator would use this alongside other RTT statistics to compute jitter, latency variance, and MOS (Mean Opinion Score) for VoIP quality monitoring.
