What is etherDMAUnderruns?
Count of times the Ethernet transmit DMA engine ran out of data to send mid-frame, corrupting the transmission. This is a hardware/bus-throughput symptom, often tied to system load rather than network conditions.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.23.2.11.3.19 snmpwalk -v2c -c public <target> FASTPATH-MIB::etherDMAUnderruns
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.23.2.11.3.19.1 snmpget -v2c -c public <target> FASTPATH-MIB::etherDMAUnderruns.1
