ibIfPortStatExcBufOverrunErrs
Module: IB-IF-MIB
OID (symbolic): IB-IF-MIB::ibIfPortStatExcBufOverrunErrs
OID (numeric): 1.3.6.1.3.117.2.1.1.1.14
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of times that OverrunErrors consecutive flow control update periods occurred with at least one overrun error in each period.
What is ibIfPortStatExcBufOverrunErrs?
This counter tracks how many times the port experienced buffer overrun errors in a sustained series of consecutive flow-control update periods. A nonzero count points to persistent buffer exhaustion on the receive side, suggesting the port can't keep up with incoming traffic rate even with flow control active. An admin seeing this counter increase would investigate whether the receiving device or downstream path is undersized for the offered load.
