Bulk Statistics Object Lists

Bulk Statistics Object Lists
To group the MIB objects to be polled, you need to create one or more object lists. A bulk statistics object
list is a user-specified set of MIB objects that share the same MIB index. Object lists are identified using a
name that you specify. Named bulk statistics object lists allow the same configuration to be reused in different

bulk statistics schemas.

All the objects in an object list must share the same MIB index. However, the objects do not need to be in the
same MIB and do not need to belong to the same MIB table. For example, it is possible to group ifInOctets
and a CISCO-IF-EXTENSION-MIB object in the same schema, because the containing tables for both objects
are indexed by the ifIndex.
Bulk Statistics Schemas
Data selection for the Periodic MIB Data Collection and Transfer Mechanism requires the definition of a
schema with the following information:
• Name of an object list.
• Instance (specific instance or series of instances defined using a wild card) that needs to be retrieved for
• How often the specified instances need to be sampled (polling interval). The default polling interval is
A bulk statistics schema is also identified using a name that you specify. This name is used when configuring
the transfer options.

Bulk Statistics Transfer Options

After configuring the data to be collected, a single virtual file (VFile or bulk statistics file) with all collected
data is created. This file can be transferred to a network management station using FTP or TFTP. You can
specify how often this file should be transferred. The default transfer interval is once every 30 minutes. You
can also configure a secondary destination for the file to be used if, for whatever reason, the file cannot be
transferred to the primary network management station.
The value of the transfer interval is also the collection period (collection interval) for the local bulk statistics
file. After the collection period ends, the bulk statistics file is frozen, and a new local bulk statistics file is
created for storing data. The frozen bulk statistics file is then transferred to the specified destination.
By default, the local bulk statistics file is deleted after successful transfer to an network management station.

Benefits of Periodic MIB Data Collection and Transfer

Periodic MIB data collection and transfer (bulk statistics feature) allows many of the same functions as the
bulk file MIB (CISCO-BULK-FILE-MIB.my), but offers some key advantages. The main advantage is that
this feature can be configured through the CLI and does not require an external monitoring application.
