Entity MIB Implementation Report

September 2003

1.0 Introduction

This report documents implementation experience with the Entity MIB, most recently published as draft-ietf-entmib-v3-03.txt. This report consists of three parts: this summary page, MIB walks that demonstrate the compliance of each implementation, and vendor reports that describe the state of each vendor’s implementation.

.

2.0 Implementation Summary

Three implementations are described in this report:

  • Cisco’s implementation – Complete implementation
  • Nortel’s implementation – Implementation of the Entity MIB Physical Table and related objects
  • Wind River’s implementation – Implementation of the Entity MIB Logical Table and related objects

Between them, these three implementations represent two independent, interoperable implementations of each Entity MIB object.

The following table summarizes the Entity MIB objects supported by each implementation:

There were logical-to-physical and alias mapping tables included in earlier versions of the Entity MIB that were not implemented by multiple vendors. Those tables have been deprecated to allow the Entity MIB to progress to Draft Standard.
