16.1 SNMP Overview
SNMP is an application-layer communication protocol that allows ONS 15454 network devices to
exchange management information among these systems and with other devices outside the network.
Through SNMP, network administrators can manage network performance, find and solve network
problems, and plan network growth. Up to 10 SNMP trap destinations and five concurrent Cisco
Transport Controller (CTC) user sessions are allowed per node.
The ONS 15454 uses SNMP for asynchronous event notification to a network management system
(NMS). Cisco ONS system SNMP implementation uses standard Internet Engineering Task Force
(IETF) management information bases (MIBs) to convey node-level inventory, fault, and performance
management information for generic DS-1, DS-3, SONET, and Ethernet read-only management. SNMP
allows a generic SNMP manager such as HP OpenView Network Node Manager (NNM) or Open
Systems Interconnection (OSI) NetExpert to be utilized for limited management functions.
The Cisco ONS 15454 supports SNMP Version 1 (SNMPv1) and SNMP Version 2c (SNMPv2c). These
versions share many features, but SNMPv2c includes additional protocol operations and 64-bit
performance monitoring support. This chapter describes both versions and gives SNMP configuration
parameters for the ONS 15454.
