mscAtmIfVpcStatsTxCellDiscard
Module: Nortel-MsCarrier-MscPassport-AtmCoreMIB
OID (symbolic): Nortel-MsCarrier-MscPassport-AtmCoreMIB::mscAtmIfVpcStatsTxCellDiscard
OID (numeric): 1.3.6.1.4.1.562.36.2.1.114.4.140.1.42
Node type: OBJECT-TYPE
Type: PassportCounter64
Access: read-only
Description: This attribute counts the number of cells received from the bus on this connection that have been discarded.
Discarded cells are not counted in the txCell attribute.
Cells are discarded due to transmit congestion, Partial Packet Discard (PPD), Early Packet Discard (EPD), and Weighted Random Early Detection (W-RED) mechanisms, or when the connection's interface is disabled.
For CQC-based ATM cards, this attribute is applicable only to connections that relay cells without adaptation. Such connections usually have a connectionPointType of segmentEndPoint or connectingPoint. AAL1 connections are an exception to this rule; although they have a connectionPointType of connectionEndPoint, they do not do adaptation at this point. For Vpts, this attribute provides an aggregated total of all txCellDiscard values for all such connections associated with the Vpt.
For Vccs on CQC-based ATM cards, if the connection segments frames into cells, this attribute is not applicable and is not displayed.
The counter wraps to zero if it exceeds its maximum value of (2**64)-1.
