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
a
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

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.
