etherPortRxFifoOverrunErrors
Module: PORT-MIB
OID (symbolic): PORT-MIB::etherPortRxFifoOverrunErrors
OID (numeric): 1.3.6.1.4.1.5812.3.3.1.38
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: The total number of packets dropped by the GMAC due to the occurence of a receive FIFO overrun (gig only- supported by GMAC-D2 and later)
What is etherPortRxFifoOverrunErrors?
This counts packets dropped by the GMAC due to a receive FIFO overrun, meaning incoming data arrived faster than the receive buffer could be drained, gigabit-only on GMAC-D2 and later. It's the receive-side counterpart to etherPortRxOverrun and signals the same kind of buffering pressure on inbound traffic. An admin would correlate this with overall port utilization to see if the port is simply oversubscribed.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5812.3.3.1.38 snmpwalk -v2c -c public <target> PORT-MIB::etherPortRxFifoOverrunErrors
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.5812.3.3.1.38.1 snmpget -v2c -c public <target> PORT-MIB::etherPortRxFifoOverrunErrors.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> etherPortRxFifoOverrunErrors.1
