SNMP Overview

SNMP is an application-layer protocol that provides a message format for communication between SNMP managers and agents. SNMP provides a standardized framework and a common language used for the monitoring and management of resources in a network.

Support for SNMP and system logging are part of Polycom’s management instrumentation solution. For detailed information on using the manageability instrumentation solution with your Polycom products, see

SNMP Framework

The SNMP framework has three parts:

●An SNMP manager

The SNMP manager is the system used to control and monitor the activities of network hosts using SNMP. A variety of network management applications are available for use with SNMP. It is important to note that you should understand how your SNMP management system is configured to properly configure your Polycom system SNMP transport protocol requirements, SNMP version requirements, SNMP authentication requirements, and SNMP privacy requirements. For information on using SNMP management systems, see the appropriate documentation for your application.

●An SNMP agent

The SNMP agent is the software component within the Polycom system that maintains the data for the system and reports these data, as needed, to managing systems. The agent and MIB reside on the same system.

●A MIB

The MIB (Management Information Base) is a virtual information storage area for network management information, which consists of collections of managed network objects. You can configure the SNMP agent for a particular system MIB. The agent gathers data from the MIB, the repository for information about system parameters and network data. Polycom systems include Polycom-specific MIBs with every system as well as third-party MIBs. Polycom MIBs are
