Fibre Alliance MIB Object Types
connUnitEventIndex [connUnitEventTable]
Syntax
Integer of size 1 to 2147483647
Access
Read-only
Status
Mandatory
Description
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 is no longer available.
The index value is an incrementing integer starting from one (1) every time there is a table reset.
On table reset, all contents are emptied and all indices are set to zero (0). 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 causes the index value to roll
over and start at one (1) again.
Note:
connUnitEventId [connUnitEventTable]
Syntax
Integer
Access
Read-only
Status Deprecated
Description The internal event ID. Incremented for each event, ranging between 0 and connUnitMaxEvents.
Not used as table index to simplify the agent implementation. When this reaches the end of the
range specified by connUnitMaxEvents, the Id rolls over to start at zero. This value is set back to
zero at reset. The relationship of this value to the index is that internal event ID may represent a
smaller number than a 32 bit integer (for example, max 100 entries) and would only have a value
range up to connUnitMaxEvents.
Note:
2-46
Mapped to swEventIndex.
Same as connUnitEventIndex.
