To find the QoS service policies that are applied to a specific interface (more generically referred to as
a target), you must search the entire cbQosServicePolicyTable within the
CISCO-CLASS-BASED-QOS-MIB. This process can be very time consuming in large scale
configurations, and therefore, is not feasible.

CISCO-CLASS-BASED-QOS-MIB. This process can be very time consuming in large scale
configurations, and therefore, is not feasible.
A solution was to create the CISCO-CBP-TARGET-MIB, a more generic MIB that allows any type of
target to be mapped to the service policies that are applied to it.
target to be mapped to the service policies that are applied to it.
The CISCO-CBP-TARGET-MIB maps policy targets to their corresponding attached service policies by
providing a link to the policy instance (service policy) and the policy-map configuration data by using
row pointers to the tables that manage each one. For policy types in the
CISCO-CLASS-BASED-QOS-MIB, the CISCO-CBP-TARGET-MIB maps targets to their
cbQosServicePolicyTable and cbQosPolicyMapCfgTable rows, respectively.
