mscAal1CesBufferUnderflows
Module: Nortel-MsCarrier-MscPassport-CircuitEmulationServiceMIB
OID (symbolic): Nortel-MsCarrier-MscPassport-CircuitEmulationServiceMIB::mscAal1CesBufferUnderflows
OID (numeric): 1.3.6.1.4.1.562.36.2.1.119.14.1.4
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: This attribute counts the number of times the AAL1 reassembly buffer underflows. In the case of a continuous buffer starvation, a single buffer underflow event will be counted. The counter wraps when the maximum value is exceeded.
What is mscAal1CesBufferUnderflows?
Counts how many times the AAL1 reassembly buffer has run dry (starved for cells); a continuous starvation event only increments this once, so a rising count indicates repeated, distinct loss-of-cells events rather than one long outage.
