44.7.1 About SNMP
Simple Network Management Protocol (SNMP) is an application layer protocol used to manage and
monitor TCP/IP-based devices. SNMP is used to exchange management information between the
network management system (NMS) and a network element (NE). A manager station can manage and
monitor the OLT through the network via SNMP version 1 (SNMPv1), SNMP version 2c or SNMP version 3.
The next figure illustrates an SNMP management operation. SNMP is only available if TCP/IP is
configured.
Figure 225 SNMP Management Model
An SNMP managed network consists of two main components: agents and a manager.
