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.
