Description: This is a count of the number of packets dropped by this port due to an underflow in the transmit FIFO. When an underflow is detected, transmission is immediately aborted after sending a known bad (inverted) CRC sequence. The FIFO underflow error takes precedence over all other errors if this counter is incremented, then none of the other packet type counters are incremented.
What is acdPortTxStatsFifoErrors?
This counter counts packets dropped because the transmit buffer (FIFO) ran out of data mid-transmission, forcing the port to abort and send a corrupted frame. Network engineers watch for this error to detect problems with the system delivering data fast enough to the port—often a sign of CPU overload or memory pressure on the device. If this counter increments frequently (for example, once per second), it signals the device cannot keep up with the port's transmission speed and may need optimization.
