CHAPTER1 Introduction Mediant 800 SBC | SNMP Reference Guide

1 Introduction

This document provides you with supplementary information on Simple Network

Management Protocol (SNMP) based management for your AudioCodes device. This

information complements the information provided by the device's User's Manual , and

includes SNMP configuration, SNMP traps (events and alarms), and SNMP performance

monitoring MIBs.

●The SNMP MIB manual is supplied in the Software Release Package delivered

with the device.

●For large deployments (for example, multiple devices in globally distributed

enterprise offices) that need to be managed by central personnel, it is

recommended to use AudioCodes One Voice Operations Center (OVOC). OVOC

is not included in the device's supplied package. Contact AudioCodes for more

information on its OVOC solution for large VoIP deployments.
