= Cisco CBQoS property extender
This property extender is used only in very specific circumstances.
:description: Cisco CBQoS property extender in {page-component-title} to include string properties across `ifXTable` and some MIB tables.

== When to use Cisco CBQoS property extender

The Cisco CBQoS property extender is designed specifically and exclusively to include string properties across `ifXTable` and the several MIB tables that make up the Cisco class-gased QoS MIB.
It is not useful for any other sets of target and source tables.

== Configure Cisco CBQoS extended properties

The complex relationships among the various Cisco CBQoS tables are encapsulated in the code of this property extender class.
As a result, this extender takes only a single parameter, `target-property`, whose value must be one of `policyName`, `classMapName`, `interfaceAlias`, or `interfaceName`.
