SNMP MIB Installation and Configuration

This chapter explains how to read and understand SNMP MIB as it relates to the Cisco

ONS 15216 EDFA2. This chapter is a reference of all ONS 15216 EDFA2 SNMP commands that are used in a network management system (NMS). For provisioning the ONS 15216 EDFA2, see Chapter 4, “Provisioning Using ASH and SNMP”.

5.1 SNMP Overview

Simple Network Management Protocol (SNMP) is an application-layer communication protocol that allows network devices to retrieve and modify the value of management information, as well as provide event notification to a NMS.

The ONS 15216 EDFA2 SNMP implementation uses proprietary and standard Internet Engineering Task Force (IETF) MIBs to convey inventory, fault, and performance management information.

SNMP allows limited management of the ONS 15216 EDFA2 by a generic, third-party SNMP manager (for example, HP OpenView Network Node manager [NNM] or Open Systems Interconnection [OSI] NetExpert).

The ONS 15216 EDFA2 supports SNMP Version 1 (SNMPv1) and SNMP Version 2c (SNMPv2c) protocols.

5.1.1 SNMP Components

An SNMP-managed network consists of three primary components:

•Managed devices

•Agents

•Management systems

A managed device is a network node that contains an SNMP agent and resides on an SNMP-managed network. Managed devices collect and store management information and use SNMP to make this information available to management systems that use SNMP. Managed devices include routers, access servers, switches, bridges, hubs, computer hosts, and network elements such as the ONS 15216 EDFA2.
