Trap Name
Trap Description
OID
newRoot
The newRoot trap indicates that the sending agent has become
the new root of the Spanning Tree; the trap is sent by a bridge
soon after its election as the new root, e.g., upon expiration of the
Topology Change Timer, immediately subsequent to its election.
Implementation of this trap is optional.
1.3.6.1.2.1.17.0.1
topologyChange
A topologyChange trap is sent by a bridge when any of its
configured ports transitions from the Learning state to the
Forwarding state, or from the Forwarding state to the Blocking
state. The trap is not sent if a newRoot trap is sent for the same
transition. Implementation of this trap is optional.
1.3.6.1.2.1.17.0.2
dot1agCfmFaultAlarm
A MEP has a persistent defect condition. A notification (fault
alarm) is sent to the management entity with the OID of the MEP
that has detected the fault. Whenever a MEP has a persistent
defect, it may or may not generate a Fault Alarm to warn the
system administrator of the problem, as controlled by the MEP
Fault Notification Generator State Machine and associated
Managed Objects. Only the highest-priority defect, as shown in
Table 20-1, is reported in the Fault Alarm. If a defect with a higher
priority is raised after a Fault Alarm has been issued, another
Fault Alarm is issued. The management entity receiving the
notification can identify the system from the network source
address of the notification, and can identify the MEP reporting the
defect by the indices in the OID of the
dot1agCfmMepHighestPrDefect variable in the notification:
dot1agCfmMdIndex - Also the index of the MEP's Maintenance
Domain table entry (dot1agCfmMdTable). dot1agCfmMaIndex -
Also an index (with the MD table index) of the MEP's Maintenance
Association network table entry (dot1agCfmMaNetTable), and
(with the MD table index and component ID) of the MEP's MA
component table entry (dot1agCfmMaCompTable).
dot1agCfmMepIdentifier - MEP Identifier and final index into the
MEP table (dot1agCfmMepTable).
Binding:
1.dot1agCfmMepHighestPrDefect
1.3.111.2.802.1.1.8.0.1
dot3OamThresholdEvent
A dot3OamThresholdEvent notification is sent when a local or
remote threshold crossing event is detected. A local threshold
crossing event is detected by the local entity, while a remote
threshold crossing event is detected by the reception of an
Ethernet OAM Event Notification OAMPDU that indicates a
threshold event. This notification should not be sent more than
once per second. The OAM entity can be derived from extracting
the ifIndex from the variable bindings. The objects in the
notification correspond to the values in a row instance in the
dot3OamEventLogTable. The management entity should
periodically check dot3OamEventLogTable to detect any missed
events.
Binding:
1.dot3OamEventLogTimestamp
2.dot3OamEventLogOui
3.dot3OamEventLogType
4.dot3OamEventLogLocation
5.dot3OamEventLogWindowHi
6.dot3OamEventLogWindowLo
7.dot3OamEventLogThresholdHi
8.dot3OamEventLogThresholdLo
9.dot3OamEventLogValue
10.dot3OamEventLogRunningTotal
11.dot3OamEventLogEventTotal
1.3.6.1.2.1.158.0.1
swPktStormOccurred
This trap is sent when a packet storm is detected by a packet
storm mechanism and a shutdown action is taken.
Binding:
1: swPktStormCtrlPortIndex
1.3.6.1.4.1.171.12.25.5.
0.1
swPktStormCleared
The trap is sent when the packet storm is cleared by the packet
storm mechanism.
Binding:
1: swPktStormCtrlPortIndex
1.3.6.1.4.1.171.12.25.5.
0.2
swPktStormDisablePort
The trap is sent when the port is disabled by the packet storm
1.3.6.1.4.1.171.12.25.5.
