SNMP MIB Installation and Configuration
This chapter explains how to read and understand SNMP MIB as it relates to the 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”.
SNMP Overview
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 an NMS.
The ONS 15216 EDFA2 SNMP implementation uses 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.
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.
ONS 15216 EDFA2 SNMP Elements
The following three SNMP elements are used with the ONS 15216 EDFA2:
