ZYXEL-MRSTP-MIB
AI MIB Summary
The ZYXEL-MRSTP-MIB enables monitoring and management of Multiple Rapid Spanning Tree Protocol (MRSTP) instances, topology states, and port configurations on Zyxel network switches. It provides access to critical metrics such as bridge IDs, root path costs, port roles, and rapid transition timers to ensure loop-free Layer 2 network stability.
