An authenticationFailure trap signifies that
the sending protocol entity is the address of
a protocol message that is not properly
authenticated.While implementations
the SNMP must be capable of generating
this trap, they must also be capable of
suppressing the emission of such traps via
an implementation- specific mechanism.
The SNMP trap that is generated when an
alarm entry crosses its rising threshold and
generates an event that is configured for
sending SNMP traps.
The SNMP trap that is generated when an
alarm entry crosses its falling threshold and
generates an event that is configured for
sending SNMP traps.
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 action of the Topology
Change Timer immediately subsequent to
its election. Implementation of this trap is
optional.
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.
A lldpRemTablesChange notification is sent
when the value of
lldpStatsRemTableLastChangeTime
changes. It can be utilized by an NMS to
trigger LLDP remote systems table
maintenance polls.
sensing a change in the topology that
indicates that a new remote device
attached to a local port, or a remote device
disconnected or moved from one port to
another.
The trap is sent when any parameter value
exceeds the alarm threshold value or
recovers to normal status depending on the
configuration of the trap action.
The trap is sent when any parameter value
exceeds the warning threshold value or
recovers to normal status depending on the
configuration of the trap action.
