# Bus Segment table

The Bus Segment table contains information about each bus segment, such as type of bus segment, description, and number of occupied slots. There can be many PCI (or CompactPCI) bus segments.

A busSegmentIndex object, whose value is assigned by the NMS Chassis agent, identifies each busSegmentEntry object.

busSegmentEntry objects are added to the table when a board is added to a new bus segment. If all boards are extracted, that bus segment is deleted from the table.

The objects in the Bus Segment table are:

Object | Description
--- | ---
busSegmentTable | Starts the Bus Segment table.
busSegmentEntry | Starts a row of the Bus Segment table.
busSegmentIndex | Number of this row in the Bus Segment table.
busSegmentType | Bus type.
busSegmentDescr | Describes the bus segment.
busSegmentSlotsOccupied | Specifies the number of occupied slots in this bus segment.
