Entries are automatically created and deleted from this
table, and exist whenever the OAM entity supports Ethernet OAM
events (as indicated by the eventSupport bit in
cdot3OamFunctionsSuppported). Values in the table are
maintained across changes to the value of cdot3OamOperStatus.
Event configuration controls when the local management entity
sends Event Notification OAMPDUs to its OAM peer, and when
certain event flags are set or cleared in OAMPDUs.
