Description: Indicates the operational source of QoS provisioning policy for this interface.

When the value of the object qosPrOperPolicySource is local(2), the QoS provisioning policy for this interface is taken from device's local configuration. If qosPrOperPolicySource is configured to cops(3), the current operational source of QoS provisioning policy will depend on the configuration of qosPrIfAdminPolicySource object.

Here is the logic.

IF qosPrOperPolicySource == local(2) THEN qosPrIfOperPolicySource is local(2) ELSE IF qosPrOperPolicySource == cops(3) THEN IF qosPrIfAdminPolicySource == cops(3) THEN qosPrIfOperPolicySource is cops(3) ELSE qosPrIfOperPolicySource is local(2) ELSE qosPrIfOperPolicySource is none(1) END END

For example, if qosPrOperPolicySource shows local(2), although the qosPrIfAdminPolicySource is configured cops(3), the QoS provisioning policy running on this interface is from local device configuration. It means this object will be local(2).

Note that when qosPrIfAdminPolicySource transitions to cops(3) if qosPrOperPolicySource is cops(3), qosPrIfOperPolicySource will normally also transition to cops(3). In this situation, it is possible that qosPrIfOperPolicySource's transition will not occur immediately because the system is initializing the COPS function at the system boot up time, but rather after a small time lag to complete certain operations before going 'cops'.
