NORTEL-NETWORKS-RAPID-SPANNING-TREE-MIB
AI MIB Summary
The NORTEL-NETWORKS-RAPID-SPANNING-TREE-MIB provides SNMP access to monitor and configure Rapid Spanning Tree Protocol (RSTP) instances, topology states, and port parameters on Nortel Networks switching hardware. It enables the retrieval of specific RSTP metrics including port roles, bridge IDs, path costs, and state transitions to detect and resolve Layer 2 loop conditions.
