Introduction

The SNMPManager Driver communicates with SNMP agents using the SNMP (Simple Network Management Protocol) protocol. According to SNMP nomenclature, agents are network devices (switches, routers, multiplexers, no-breaks, etc.) that produce information to manage, which are therefore sent to a management system, in this case the SNMPManager Driver.

This Driver currently supports versions V1, V2C and V3 of the SNMP specification, which allows the following resources:

•Communication with up to 50 devices using a single Driver (DLL)

•Importing or creating Tags from devices using MIB files

•Reading variables asynchronously by grouping several requests into a single query (polling)

•Writing parameters synchronously

•Supporting unsolicited messages (receiving SNMP Traps)
