RFC 1493 Traps
newRoot 1.3.6.1.2.1.17.0.1 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.
topologyChange 1.3.6.1.2.1.17.0.2 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 Discarding
state. The trap is not sent if a newRoot
trap is sent for the same transition.
SNMPv2 Traps
coldStart 1.3.6.1.6.3.1.1.5.1 A coldStart trap signifies that the
SNMPv2 entity, acting in an agent role,
is reinitializing itself and that its
configuration may have been altered.
warmStart 1.3.6.1.6.3.1.1.5.2 A warmStart trap signifies that the
SNMPv2 entity, acting in an agent role,
is reinitializing itself such that its
configuration is unaltered.
linkDown * 1.3.6.1.6.3.1.1.5.3 A linkDown trap signifies that the SNMP
entity, acting in an agent role, has
detected that the ifOperStatus object for
one of its communication links is about
to enter the down state from some other
state (but not from the notPresent
state). This other state is indicated by
the included value of ifOperStatus.
linkUp* 1.3.6.1.6.3.1.1.5.4 A linkUp trap signifies that the SNMP
entity, acting in an agent role, has
detected that the ifOperStatus object for
one of its communication links left the
down state and transitioned into some
other state (but not into the notPresent
state). This other state is indicated by
the included value of ifOperStatus.
authenticationFailure* 1.3.6.1.6.3.1.1.5.5 An authenticationFailure trap signifies
that the SNMPv2 entity, acting in an
agent role, has received a protocol
message that is not properly
authenticated. While all
implementations of the SNMPv2 must be
capable of generating this trap, the
snmpEnableAuthenTraps object
indicates whether this trap will be
generated.
RMON Events (V2)
risingAlarm 1.3.6.1.2.1.16.0.1 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.
fallingAlarm 1.3.6.1.2.1.16.0.2 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.
