Description: Number of bad frames (due to Transmit FIFO underrun) transmitted.
What is etherPortStatsTxBadFifoUnderrun?
This counts frames transmitted with errors caused by a Transmit FIFO underrun, meaning the hardware's output buffer ran dry mid-frame before all data was ready. An admin sees this rise when the port's transmit path can't keep data flowing fast enough, often pointing to a hardware or bus-bandwidth issue on that card. Persistent underrun errors on a specific port are a strong hint to check that card's health rather than the cabling.
