The event table is a list of active Cisco LiveData events.
The SNMP agent constructs the event table at startup and it
fills the table as events are generated.
Events with the same cldEventID value will overwrite existing
events in the table with the same EventID (i.e. only the most
recent will persist).
Event table entries cannot be added to or deleted from the
table by the management station. All objects in this table
are read-only.
