Each connectivity unit has its own event buffer. As it wraps, it may
write over previous events. This object is an index into the buffer. It is
recommended that this table be read using 'getNext's to retrieve the
initial table. The management application should read the event table
at periodic intervals and then determine if any new entries were
added by comparing the last known index value with the current
highest index value. The management application should then
update its copy of the event table. If the read interval is too long, it is
possible that there may be events that may not be contained in the
agent's internal event buffer.
For example, an agent may read events 50-75. At the next read
interval, connUnitEventCurrID is 189. If the management app tries
to read event index 76, and the agent's internal buffer is 100 entries
max, event index 76 will no longer be available.
The index value is an incrementing integer starting from one every
time there is a table reset. On table reset, all contents are emptied and
all indices are set to zero. When an event is added to the table, the
event is assigned the next higher integer value than the last item
entered into the table. If the index value reaches its maximum value,
the next item entered will cause the index value to roll over and start
at one again.

The internal event Id. Incremented for each event, ranging between 1
and connUnitMaxEvents. Not used as table index to simplify the
agent implementation. When this reaches the end of the range
