What is nncVSUnderrunSeconds?
This counter tracks the number of seconds during which the channel declared an underrun condition. Underrun seconds indicate the channel's playout buffer ran dry, typically from network jitter or packet loss, degrading voice quality with audible gaps. An admin seeing underrun seconds climb alongside nncVSBufferUnderflows would look at network jitter or QoS settings for that channel.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.123.3.72.1.2.1.1.3 snmpwalk -v2c -c public <target> NNCVS-MIB::nncVSUnderrunSeconds
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.123.3.72.1.2.1.1.3.1 snmpget -v2c -c public <target> NNCVS-MIB::nncVSUnderrunSeconds.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> nncVSUnderrunSeconds.1
