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.
Private Traps
swPowerStatus ChangeTrap 1.3.6.1.4.1.259.12.1.2.2.1.0.1 This trap is sent when the power state changes.
swFanFailureTrap 1.3.6.1.4.1.259.12.1.2.2.1.0.17 This trap is sent when the fan fails.
swFanRecoverTrap 1.3.6.1.4.1.259.12.1.2.2.1.0.18 This trap is sent when fan failure has recovered.
swThermalRisingNotification 1.3.6.1.4.1.259.12.1.2.2.1.0.58 This trap is sent when the temperature is over the
switchThermalActionRisingThreshold.
