NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB
AI MIB Summary
The NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB enables SNMP-based monitoring and configuration of Multiple Spanning Tree Protocol (MSTP) instances, specifically tracking MST region identifiers, instance-to-VLAN mappings, and port state transitions on Nortel Networks switching hardware. This module facilitates the management of loop-free Layer 2 topologies by exposing MSTP-specific counters and status variables required for validating spanning tree convergence and detecting topology changes across VLAN groups.
