PRVT-SPANNING-TREE-MIB

AI MIB Summary

The PRVT-SPANNING-TREE-MIB provides vendor-specific monitoring and management of Layer 2 loop prevention mechanisms, specifically tracking spanning tree topology states, port roles, and fast ring protocol convergence metrics. This module enables the collection of critical operational data such as bridge ID changes, port state transitions, and ring failure events to ensure network stability and rapid fault recovery.

The private MIB module for management of the spanning tree and fast ring protocols.

stTopologyChangeA 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 Blocking state. The trap is not sent if a newRoot trap is sent for the same transition. Implementation of this trap is optional.
NOTIFICATION-TYPE
.1.3.6.1.4.1.738.1.5.107.0.1
stNewRootThe 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. Implementation of this trap is optional.
