tnCesEventThresholdUnderrun
Module: TN-CES-MIB
OID (symbolic): TN-CES-MIB::tnCesEventThresholdUnderrun
OID (numeric): 1.3.6.1.4.1.868.2.5.60.1.4.5
Node type: OBJECT-TYPE

Description: Threshold above which to report underrun errors. When this value is zero, reporting is disabled.
What is tnCesEventThresholdUnderrun?
The count of TDM jitter-buffer underrun errors (0-65535, meaning missing packets caused the buffer to run empty) that must be exceeded before an event is reported; zero disables this specific alert. Underruns directly affect voice/data quality on the circuit, so this is one of the more operationally important CES thresholds to keep enabled.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.868.2.5.60.1.4.5 snmpwalk -v2c -c public <target> TN-CES-MIB::tnCesEventThresholdUnderrun
Get a specific instance (index 1):
