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
the Polycom RealPresence Manageability Instrumentation Solution Guide.
This section includes the following topics:
● SNMP Framework
● SNMP Notifications
● SNMP Versions
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
