users to SNMP views.

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.
