SNMP
This chapter explains Simple Network Management Protocol (SNMP) as implemented by the Cisco ONS
15454.
11.1 SNMP Overview
SNMP is an application-layer communication protocol that allows network devices to exchange
management information. SNMP enables network administrators to manage network performance, find
and solve network problems, and plan network growth.
The ONS 15454 uses SNMP to provide asynchronous event notification to a network management
system (NMS). ONS SNMP implementation uses standard Internet Engineering Task Force (IETF)
MIBs to convey node-level inventory, fault, and performance management information for generic
read-only management of DS-1, DS-3, SONET, and Ethernet technologies. SNMP allows limited
management of the ONS 15454 by a generic SNMP manager, for example HP OpenView Network Node
Manager (NNM) or Open Systems Interconnection (OSI) NetExpert.
The Cisco ONS 15454 supports SNMP Version 1 (SNMPv1) and SNMP Version 2c (SNMPv2c). Both
versions share many features, but SNMPv2c includes additional protocol operations. This chapter
describes both versions and explains how to configure SNMP on the ONS 15454. Figure 11-1 illustrates
a basic network managed by SNMP.
