SNMP Overview

Simple Network Management Protocol (SNMP) is a communication protocol that allows network management systems to manage resources across a network. SNMP can be transmitted over TCP or UDP.

SNMP communication takes place between the management system and SNMP agents, which are the hardware and software that the management system monitors. An agent collects and stores local system information and makes this information available to the management system via SNMP.

The Polycom DMA system software includes an SNMP agent. It translates local system information into the format defined by the Management Information Base (MIB). SNMP access to the DMA system is read-only. SET operations are not supported, but GET, GETNEXT, GETBULK, NOTIFY, and INFORM are.

The DMA system resides on a Polycom-branded Dell server running the CentOS Linux operating system. The DMA software, CentOS, and the Dell server each have their own MIB and SNMP agent. But the default Linux SNMP daemon agent (snmpd) aggregates the information from all three and makes it available to network management systems.
