The 9920 MIB Reference Guide for version 21.2.2.0 provides a
comprehensive guide on the Management Information Base (MIB) structure and supported MIB
objects for Extreme Networks' 9920 platform. It covers the hierarchical organization of MIBs,
object identifiers (OIDs), and how to access and query MIB variables using MIB browsers. Key
supported MIBs include the Interface Group MIB, System Group MIB, Entity MIB, and ifXTable
Extended MIB. Each section outlines the specific OIDs, data types, and functions of the MIB
objects, such as interface states, traffic statistics, system information, and entity
descriptions. Detailed descriptions of MIB access levels, including read-only, read-write, and
read-create permissions, enable effective network management and monitoring. This reference is
essential for network administrators managing and troubleshooting Extreme 9920
environments.
