Module: PORT-MIB
OID (symbolic): PORT-MIB::etherPortStatsTxDropFifoOverrun

Description: Number of frames dropped due to Transmit FIFO underrun.
What is etherPortStatsTxDropFifoOverrun?
This counts frames dropped, rather than sent corrupted, because of a Transmit FIFO underrun condition on this port. It complements etherPortStatsTxBadFifoUnderrun, which tracks frames that went out with errors rather than being dropped outright. A rising drop count here means the port is losing outbound traffic entirely, which is more serious for throughput than a badly formed frame.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5812.3.3.1.19 snmpwalk -v2c -c public <target> PORT-MIB::etherPortStatsTxDropFifoOverrun
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.5812.3.3.1.19.1 snmpget -v2c -c public <target> PORT-MIB::etherPortStatsTxDropFifoOverrun.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> etherPortStatsTxDropFifoOverrun.1
