|prod| supports :abbr:`SNMP (Simple Network Management Protocol)` traps. Traps
|
|
send unsolicited information to monitoring software when significant events
|
|
occur.
|
|
|
|
The following traps are defined.
|
|
|
|
.. _traps-ul-p1j-tvn-c5:
|
|
|
|
- **wrsAlarmCritical**
|
|
|
|
- **wrsAlarmMajor**
|
|
|
|
- **wrsAlarmMinor**
|
|
|
|
- **wrsAlarmWarning**
|
|
|
|
- **wrsAlarmMessage**
|
|
|
|
- **wrsAlarmClear**
|
|
|
|
- **wrsAlarmHierarchicalClear**
|
|
|
|
.. note::
|
|
Customer Logs always result in **wrsAlarmMessage** traps. |prod| uses Wind
|
|
River Systems (**wrs**) Enterprise Registration and Alarm MIBs. See
|
|
:ref:`SNMP Overview <snmp-overview>` for details.
|
|
|
|
For Critical, Major, Minor, Warning, and Message traps, all variables in the
|
|
active alarm table are included as varbinds \(variable bindings\), where each
|
|
varbind is a pair of fields consisting of an object identifier and a value
|
|
for the object.
|
|
|
|
For the Clear trap, varbinds include only the following variables:
|
|
|
|
.. _traps-ul-uks-byn-nkb:
|
|
|
|
- <AlarmID>
|
|
|
|
- <EntityInstanceID>
|
|
|
|
- <DateAndTime>
|
|
|
|
- <ReasonText>
|
|
|
|
For the HierarchicalClear trap, varbinds include only the following variables:
|
|
|
|
.. _traps-ul-isn-fyn-nkb:
|
|
|
|
- <EntityInstanceID>
|
|
|
|
- <DateAndTime>
|
|
|
|
- <ReasonText>
|
|
|
|
For all alarms, the Notification Type is based on the severity of the trap or
|
|
alarm. This is done to facilitate the interaction with most SNMP trap viewers
|
|
which typically use the Notification Type to drive the coloring of traps, that
|
|
is, red for critical, yellow for minor, and so on. |
