Sequence ::= { connUnitEventEntry 1 } FC Management MIB B connUnitEventIndex Syntax Access Status Description Sequence INTEGER (1..2147483647) read-only mandatory 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. ::= { connUnitEventEntry 2 } connUnitEventId Syntax Access Status Description INTEGER read-only deprecated 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 Event Group B-39
