documentation.
l
Test: Click to test communication with the device and the MIB OID number.
l
Operator: Select the operator used to test the condition.

Management Information Base Object Identifiers
A Management Information Base (MIB) is a database of Object Identifiers (OIDs) that can be used to monitor
device objects using SNMP. An MIB OID can point be a printer tray, cartridge or hard disk, or to modem
mode. Using an SNMP condition, PReS Workflow can communicate with a device located at a given IP
address and request the status of the object identified by a given MIB OID number. Object Identifiers are
typically assigned and registered by device manufacturers. They are based on a standard known as
Abstract Syntax Notation One (often referred to as the ASN.1 standard).
On Error Tab
The On Error tab is common to all tasks. Details can be found in the" Task Properties Dialog" on page663.
