13.1 SNMP Overview

SNMP is an application-layer communication protocol that allows ONS 15600 SDH 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 15600 SDH uses SNMP for asynchronous event notification to a network management system
(NMS). ONS SNMP implementation uses standard Internet Engineering Task Force (IETF) management
information bases (MIBs) to convey node-level inventory, fault, and performance management
information for SDH 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.
