etherPortStatsTxUndersize
Module: PORT-MIB
OID (symbolic): PORT-MIB::etherPortStatsTxUndersize
OID (numeric): 1.3.6.1.4.1.5812.3.3.1.15
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: Number of packets less than 64 bytes transmitted.
What is etherPortStatsTxUndersize?
This counts packets transmitted on the port that were smaller than the 64-byte Ethernet minimum. Legitimate traffic should never generate undersized frames, so a nonzero and growing count here usually points to a hardware or driver problem on the sending side. An admin troubleshooting intermittent connectivity issues would check this counter as one sign of a misbehaving NIC or switch port.
Examples
