Module: NNCVS-MIB
OID (symbolic): NNCVS-MIB::nncVSBufferOverflows
OID (numeric): 1.3.6.1.4.1.123.3.72.1.2.1.1.5
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: This count gives the number of jitter buffer overflows.
What is nncVSBufferOverflows?
This counter tracks the number of times the channel's jitter buffer filled beyond capacity, or overflowed. Overflows happen when packets arrive faster than they can be played out, causing the buffer to discard data and again degrade voice quality, so an admin would use this alongside underflow counts to tune buffer sizing. A card consistently showing buffer overflows on one channel but not others suggests a per-channel jitter-buffer misconfiguration rather than a network-wide issue.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.123.3.72.1.2.1.1.5 snmpwalk -v2c -c public <target> NNCVS-MIB::nncVSBufferOverflows
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.123.3.72.1.2.1.1.5.1 snmpget -v2c -c public <target> NNCVS-MIB::nncVSBufferOverflows.1
