The following list describes the major changes that have been made to the NiagaraAX Snmp Driver since the last version of this document was released.
MIB compiler improvements
The standard MIBs are now built into the snmp driver so you do not need to manually access them or point to them if you require them as dependent MIBs. See About locally generated MIBs.
Create custom MIBs
You can now create a custom MIB on the Local Device. The custom MIB will include entries for the current MIB objects as well as Export Tables. See About locally generated MIBs.
Snmp Servlet
You can now create a custom MIB using a station snmp servlet. See About the SNMP Servlet.
Table Object and Table Manager view
There is now a Table Object and a Table Manager view with a button. See About the Snmp Table Manager view.
Export Table and Export Table Manager view
This new feature allows you to discover existing control points on your Local Device and add them to an export table. Points in the export table are then available for discovery by an SNMP Manager (client) device. See About the Snmp Export Manager (SnmpExportTable).
Export point folders
Nested export folders are available using a button on the Snmp Export Manager view. These folder components can be nested and they adjust OIDs if points are moved between folders. Each folder is represented separately in the MIB as an input and output table, the same way that points in the Points folder are represented. See About the Snmp Export Manager (SnmpExportTable).
Additional data types supported
Added support for enum and boolean MIB objects. See SnmpBooleanExport and SnmpBooleanProxyExt, SnmpBooleanExport, and SnmpNetwork.
Discovery interface updates
New and improved Discovery process that allows you to assign multiple dependent MIBs, if desired. See About SNMP point discovery.
Snmp Objects added with Object Manager view
New SnmpObjects are added to allow values to be exposed as any Snmp ASN data type instead of just the string type supported in the tables. See About the Snmp Object Manager view.
Alarm Table capacity option
An Alarm Table capacity property is available on the SnmpNetwork component. This allows you to specify a maximum number of alarms that are allowed to be stored in memory. See ???.
MIB path property
A MIB path property is now available directly on the NMP Device component so you can specify or modify the path to a custom MIB.
