Yeastar P-Series PBX System MIB

This topic lists the Yeastar P-Series PBX System MIB objects.

MIB objects can be classified into the following categories:
  • Scalar Objects: Single-instance objects that hold a single value. These objects can be retrieved using SNMP Get.
  • Tabular Objects: Structured objects organized in tables, holding multiple related entries. These objects can be retrieved using SNMP Walk.
  • Notification Objects: Objects that define event notifications in the MIB. These objects are used by PBX to send unsolicited trap messages to the NMS when specific events occur.

The following sections list the MIB objects by category.

Scalar objects (for SNMP Get)

Tip: To quickly add scalar objects to Network Management System (NMS), you can download the Yeastar PBX MIB file, and import the file to NMS.
