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.

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.
