The MIB module for managing devices that support Multiple &
Rapid Spanning Trees Protocol and algorithm. It is dedicated
to reflect IEEE Std 802.1s.
Note: This contains the MIB objects defined in MSTP-MIB of
ruzin-mstp-mib-02.txt.
wRootBridge trap indicates that the
sending agent has become the new root of the
Spanning Tree in the CIST or in any MSTI; 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. Implementation of this trap is
optional.
mstpNewRootPort
.1.3.6.1.4.1.6027.20.2.0.2
wRootPort trap indicates that the
sending agent has changed the root Port of the
Spanning Tree in the CIST or in any MSTI. If the instance
has become a root one, the sending value of the
parameter mstpXstPortIndex is equal to zero. The
trap is sent by a bridge soon after its election
as the new root Port, e.g., upon expiration of the
Topology Change Timer immediately subsequent to
its election. Implementation of this trap is
optional.
mstpTopologyChange
.1.3.6.1.4.1.6027.20.2.0.3
logyChange trap is sent by a bridge when
any of its configured ports n any instance (CIST or MSTI)
transitions from the Learning state to the Forwarding
state, or from the Forwarding state to the Blocking
state. The trap is not sent if a mstpNewRootBridge trap
is sent for the same transition. Implementation of this
trap is optional.
