Module: ACD-PORT-MIB
OID (symbolic): ACD-PORT-MIB::acdPortRxStatsFifoErrors
OID (numeric): 1.3.6.1.4.1.22420.2.9.1.3.2.1.20
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: This is a count of the number of receive packets dropped or aborted due to receive FIFO overflow. The FIFO overflow error takes precedence over all other errors - if this counter is incremented, then none of the other packet type counters is incremented.
What is acdPortRxStatsFifoErrors?
This counter tracks packets dropped because the port's input buffer (FIFO) overflowed, meaning the port couldn't process packets fast enough. Network engineers view FIFO errors as a critical sign of buffer exhaustion, usually caused by sustained traffic exceeding the port's processing capacity. If FIFO errors are incrementing at 1,000 per hour, the port cannot keep up with incoming traffic and you need to reduce load or upgrade the interface.
