lpOamEnetExtendedStatistics
lp Oam Enet Extended Statistics
This attribute specifies if extended statistics are to be collected for the OamEthernet component. The extended statistics include: singleCollisionFrames, multipleCollisionFrames, lateCollisions, excessiveCollisions, carrierSenseErrors, and clearToSendSignalLoss. These statistics all require extra processing to gather and store which may have a negative impact on the overall performance of the OAM Ethernet port. If extendedStatistics is set to disabled, then these particular statistical attributes will be suppressed from display operations.
