Chapter 4 CPE Management Overview
Multi-Instance Object Support
This instruction can be used to keep the RDU up-to-date on such key parameters as the software version
and the model name. These parameters may, in turn, be used to generate other instructions, such as
configuration instructions specific to a given device type.
Table 4-2 lists the default parameters that Cisco BAC discovers.
These parameters can be updated using the API (using the /server/acs/discover/parameters property) or
via the administrator user interface (see Discovering Data from Devices, page 12-11).
Note Even if the device has a different root object, such as Device, instead of InternetGatewayDevice, the
parameters are still discovered.
Multi-Instance Object Support
In this release, the multi-instance object support introduces the ability to discover the multi-instance
object parameters from the device without specifying the actual instance number. Multi-instance object
support is available as an usability improvement in the following BAC modules to aid deployment:
• Configuration Template
• Firmware Rules Template
• Parameter Discovery
• Display Live Data Operation
This feature will be functional only when the RDU and all the DPEs are upgraded to Cisco BAC 3.8. To
configure the configuration template and the firmware template with multi-instance objects the value of
the newly introduced templateVersion attribute value should be 3.0.
