wfAtmCESStatsBufUnderflows
Module: Wellfleet-CES-MIB
OID (symbolic): Wellfleet-CES-MIB::wfAtmCESStatsBufUnderflows
OID (numeric): 1.3.6.1.4.1.18.3.4.23.4.1.2.1.13
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: Number of buffer underflows. This records the count of the number of times the CES reassembly buffer underflows. In the case of a continuous underflow caused by a loss of ATM cell flow, a single buffer underflow should be counted. If the CES IWF is implemented with multiple buffers (such as a cell level buffer and a bit level buffer), then either buffer underflow will cause this count to be incremented.
What is wfAtmCESStatsBufUnderflows?
A running count of times the CES reassembly buffer ran empty (underflowed), typically from a loss of incoming ATM cell flow; a continuous underflow is counted only once rather than repeatedly.
