AI MIB Summary

The ALCATEL-IND1-VLAN-STP-MIB monitors Spanning Tree Protocol (STP) parameters and port states specifically for VLANs on Alcatel-Lucent AOS network devices. This module provides mandatory visibility into STP topology changes, bridge port configurations, and VLAN-aware spanning tree instances to ensure loop-free network operations.

The Spanning Tree parameters for Vlans and ports that support the Spanning Tree protocol. Large percentage of this group is lifted from rfc1493.
