Module: ATMF-CES
OID (symbolic): ATMF-CES::atmfCESBufUnderflows
OID (numeric): 1.3.6.1.4.1.353.5.2.2.1.3.1.8
Node type: OBJECT-TYPE
Type: Counter32
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 atmfCESBufUnderflows?
This counter tracks how many times the reassembly buffer in a Circuit Emulation Service (CES) module has run out of data while trying to reconstruct continuous bit rate traffic from ATM cells. It measures buffer underflow events that can cause service degradation or data loss when the incoming cell stream is too slow or interrupted. Network administrators monitor this to diagnose QoS problems and cell loss on ATM-to-TDM circuits.
