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.

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

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.
