Configuring Periodic MIB Data Collection and Transfer
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.
Periodic MIB data collection and transfer is mainly targeted for medium to high-end platforms that have
sufficient local storage (volatile or permanent) to store bulk statistics files. Locally storing bulk statistics files
helps minimize loss of data during temporary network outages.
This feature also has more powerful data selection features than the bulk file MIB; it allows grouping of MIB
objects from different tables into data groups (object lists). It also incorporates a more flexible instance selection
mechanism, where the application is not restricted to fetching an entire MIB table.
4arg
4arg is Cisco's implementation of Object Size Checking (OSC). OSC is a useful static analysis utility and a
critical runtime defense for the detection and prevention of buffer overflows. 4arg captures buffer overflows
(at runtime) that are otherwise undetected by code analysis tools and human review. 4arg also carries a reporting
and logging component.
4arg refers to a theoretical fourth argument to a string copy function representing the destination buffer size.

How to Configure Periodic MIB Data Collection and Transfer
Configuring a Bulk Statistics Object List
The first step in configuring the Periodic MIB Data Collection and Transfer Mechanism is to configure one
or more object lists.
